September 2023 Medical Image of the Month: Aspergillus Presenting as a Pulmonary Nodule in an Immunocompetent Patient

Figure 1. Chest CT showing 11 x10 mm nodule in the anterior segment of the left upper lobe in the background of emphysematous and basal sub segmental atelectatic changes.

Figure 2. Lung biopsy low power (A) showing chronic inflammatory infiltrate in the interstitium along with a collection of fungus (arrow) (H&E: x40). Fungus with an area of necrosis (B) (H&E: x100). Numerous thin, narrow-angle, and branching hyphae with septa morphologically consistent with Aspergillus (C) (H&E: x400). Collection of Aspergillus (D). (Periodic acid–Schiff stain: x400).

A 32-year-old nonsmoking woman presented with complaints of recurrent hemoptysis for 5 months and dyspnea on exertion for 1 month. She denied any history of fever, cough, or COVID infection. She has hypothyroidism controlled on thyroxine 25mcg. During the evaluation, she was found to have an enhancing solitary pulmonary nodule (11 x 10 x 9mm) in the anterior segment of the left upper lobe (Figure 1). The patient was given a course of oral antibiotics (amoxicillin /clavulanic acid) and supportive treatment for hemoptysis. Sputum for Ziehl–Neelsen stain and cartridge based nucleic acid amplification test (CBNAAT) was negative. CT- guided biopsy of the nodule was performed. Histopathology showed fungal organisms which were thin, septate with acute angle branching and focal necrotic areas, morphologically consistent with Aspergillus (Figure 2). Serum-specific IgG against aspergillus antigen was normal. The patient was started on oral itraconazole 200mg BID. Follow-up after 1 month showed both symptomatic and radiological improvement. Repeat chest CT showed a significant decrease in size of the nodule.

There is a large spectrum of pulmonary aspergillosis. From this spectrum, pulmonary nodules are a less common manifestation of chronic pulmonary aspergillosis (CPA), especially in immunocompetent individuals. Aspergillus nodules are defined as small, round, discrete, and focal opacities on chest imaging. It can be further classified on basis of internal cavitation (i.e., non-cavitary nodules and cavitary nodules). Differentiating these nodules from other lung pathology may be difficult on CT findings alone and may demand further investigation like image-guided needle aspiration cytology or biopsy, blood investigations like serum Aspergillus precipitin IgG antibody and/or serum Aspergillus galactomannan. Delay in diagnoses may lead to persistence of pulmonary symptoms, and cavitation of the nodule. This entity has a favorable prognosis if managed accordingly. Although there is data regarding surgical management of aspergillus nodules, but data regarding the benefits of anti-fungal therapy in the same is limited.

Diagnosing aspergillus nodules in an immunocompetent individual is a challenge to all pulmonologists. Literature shows limited case reports and small case series on CPA presenting as non-cavitating SPN on radiology. Usually, in such cases, the diagnosis is made following removal or biopsy of the nodule(s), presuming it to be malignant. Patients diagnosed with Aspergillus nodules can’t be differentiated from lung malignant conditions based on demographics, which are usually similar. In the largest case series of Aspergillus nodules done by Muldoon EG et al. (6), 33 patients were reviewed constituting less than 10 % of the cohort of patients with CPA.  In a study done by Kang et al. (4) 77% of patients with aspergillus nodules were symptomatic and the most common symptom reported was hemoptysis. Similarly in our case hemoptysis was the chief complaint of the patient. Our patient is a woman and non-smoker similar to previous case reports and series.

In the current guidelines, the detection of serum Aspergillus precipitin IgG antibody is a key diagnostic criterion for CPA. Literature is unclear if the presence of Aspergillus IgG antibody could be considered a supportive finding in the making the diagnosis of Aspergillus nodules. Similarly, in our case also serum specific IgG against Aspergillus fumigatus was negative. Azoles are the primary treatment option in all subtypes of CPA including aspergillus nodule. Our patient also showed disease regression during itraconazole treatment. Another option for management is surgical, though it is associated with significant postoperative complications and recurrence of disease at other sites and must be reserved for selected patients.

July 2022 Medical Image of the Month: Pulmonary Nodule in the Setting of Pyoderma Gangrenosum (PG)

Figure 1. Unenhanced lung window chest CT images in the axial (A) and sagittal (B) planes show a solid, non-calcified irregular left upper lobe mass (arrow) with spiculated margins. The nodule demonstrates enhancement on soft tissue windows (C) with associated mediastinal adenopathy (arrowhead). The mass and adenopathy are FDG-avid on axial fused PET-CT image (D).

Figure 2.  (A) Photograph of one of the patient’s skin lesions.  (B) Hematoxylin and Eosin stained low-power pathological image of a biopsy specimen from a skin lesion demonstrates dense mixed neutrophilic dermal inflammation. Extensive infectious and neoplastic workup was negative. The histopathologic diagnosis was consistent with pyoderma gangrenosum.

A 70-year-old man presented with persistent cough productive of clear sputum which had persisted approximately 12 months after COVID-19 infection.  The patient reported a more recent history of night sweats and had also recently developed what he described as “blisters” on his chest wall and right shoulder starting 4 weeks prior to presentation that “opened up” giving off a bloody discharge.  The patient had been treated with trimethoprim-sulfamethoxazole and doxycycline without improvement and reported a 10-pound weight loss over the past several months.  The patient was a never-smoker with no significant travel history and a past medical history of asthma, GERD, gout, and chronic rhinitis. He had no history of autoimmune/inflammatory diseases or malignancy.

Vital signs and physical exam were normal, except for a 1 cm open wound in the center of the patient’s chest [Figure 2A].  A chest CT performed as part of the patient’s workup demonstrated a spiculated mass in the left upper lobe with adjacent mediastinal adenopathy [Figure 1A-C].  This prompted an FDG PET-CT, which demonstrated some increased uptake in the mass and adjacent lymph nodes [Figure 1D].  The mass was biopsied via bronchoscopy, pathology was nondiagnostic with rare groups of benign-appearing bronchial epithelial cells and blood.  The skin lesion was biopsied next demonstrating dense mixed neutrophilic dermal inflammation  [Figure 2B].  The diagnosis of pyoderma gangrenosum was made and the patient was treated with NSAIDs and a systemic glucocorticoid (40 mg/day, tapered over 10 weeks).steroid taper, The pulmonary mass , mediastinal lymph nodes and skin lesions all resolved over time.

Pyoderma gangrenous (PG) is a misnomer in every sense as it is neither infectious nor gangrenous.  It is a rare (3-10 cases/million/year) disorder of skin characterized by neutrophilic dermatosis which usually presents as a with inflammatory and ulcerative disorder of the skin lesions and is usually a diagnosis of exclusion (1).  PG has no pathognomonic clinical or histological findings. Majority of the cases have an underlying systemic disease, commonly inflammatory bowel disease (41%), inflammatory arthritis (20.5%) and oncologic or hematologic disorders (17.2%). While it can in any age group including children, the peak age of onset is 40-60 years. There is a slight female preponderance (2). The most common presentation is inflammatory papule or pustule that progress to a painful ulcer with violaceous undermined borders and a purulent base. The lesions commonly occur in surgical wounds within 2 weeks of surgery, a phenomenon known as pathergy, and often lead to wound dehiscence (3). The lesions may also be peristomal in patients with IBD. Extracutaneous lesions have been reported in liver, intestine, spleen, cornea, bones, muscles, CNS and rarely, in the lungs (4-6).

There have been <50 cases of pulmonary PG ever described in literature (7,8). The patients may present with non-specific symptoms of cough, dyspnea, fever, weight-loss, malaise and occasionally hemoptysis. Chest imaging may show cavitary infiltrates. The diagnosis is established by cutaneous or extracutaneous lesion biopsy of the ulcer edge showing neutrophilic infiltrate. Extensive testing should be performed , extensive testing to rule out alternative causes including infection, and malignancy, in setting of underlying inflammatory bowel disease or inflammatory arthritisautoimmune and inflammatory conditions associated with PG. Presence of pathergy and response to anti-inflammatory therapy also support the diagnosis (9). Treatment includes systemic or intralesional glucocorticoids and/or calcineurin inhibitors (3). Use of TNF alpha inhibitor, infliximab and anti-neutrophil antimicrobial dapsone has also been described in case reports (10). Most patients achieve remission within 6 months to 3 years.

Editor’s Note: Parts of this presentation were used in the June 2020 Pulmonary Case of the Month.

History of Present Illness: An 82-year-old man presented to his physician for general health maintenance as well as a complaint of persistently poor quality sleep and poor appetite with weight loss. The patient had undergone robotic-assisted radical left nephroureterectomy and cystectomy with pelvic lymph node dissection and urinary diversion for left clear cell renal cell carcinoma (staged T2a, grade 2) and transitional cell carcinoma of the bladder (carcinoma in situ at surgery), approximately 9 months earlier. The patient’s bladder malignancy was initially treated with transurethral resection, with histopathology at that procedure showing high-grade papillary urothelial malignancy with lamina propria invasion, but no muscular invasion; this procedure was followed by formal complete resection approximately 3 months later. The patient’s post-operative course was complicated by significant bleeding which required transfusion of 3 units of blood. He had undergone inferior vena caval filter placement prior to surgery when preoperative testing revealed lower extremity deep venous thrombus and pulmonary embolism.

Past Medical History: The patient’s past medical history was remarkable for atrial fibrillation treated with anticoagulation and hypertension. He also had a history of coronary artery disease and myocardial infarction with moderate systolic dysfunction His medical list included warfarin (for his atrial fibrillation), acetaminophen, vitamin supplementation, hydrochlorothiazide, atorvastatin, ramipril, metoprolol, and zolpidem. He denied allergies. The patient was a former smoker, previously smoking 2 packs-per day for 35 years, quitting over 30 years prior to presentation.

His past surgical history was remarkable for laminectomy in addition to the recent urinary surgery. He also had a history of rectal laceration complicating previous prostatectomy for prostate carcinoma (Gleason 3 + 4, T2).

Physical Examination: showed the patient to be afebrile with normal heart and respiratory rates and blood pressure. Her room air oxygen saturation was 99%. The physical examination did not disclose any salient abnormalities.

Initial Laboratory: The patient’s complete blood count and serum chemistries showed largely normal values, with the white blood cell count was normal at 6.7 x 10⁹ /L (normal, 4-10 x 10⁹ /L). His liver function testing and renal function testing parameters were also within normal limits. Echocardiography showed mildly decreased left ventricular systolic function, but this finding was stable. The patient underwent frontal chest radiography (Figure 1A).

Figure 1. A: Frontal chest radiography. B: Frontal chest radiography performed just over 1 year prior to A shows no specific abnormalities.

Which of the following represents an appropriate interpretation of his frontal chest radiograph? (Click on the correct answer to be directed to the second of fourteen pages).

1. Frontal chest radiography shows no specific abnormalities
2. Frontal chest radiograph shows a nodule
3. Frontal chest radiography shows bilateral interstitial thickening
4. Frontal chest radiography shows bilateral pleural effusions
5. Frontal chest radiography shows mediastinal and peribronchial lymph node enlargement

A 58-year-old woman with a history of orthotopic heart transplant, performed for Adriamycin-induced cardiomyopathy, treated with mycophenolate and tacrolimus, presented for routine interval follow up. The patient’s past medical history was significant for follicular thyroid carcinoma treated with total thyroidectomy and bilateral breast carcinoma in remission as well as hypothyroidism and type II diabetes mellitus. In addition to tacrolimus and mycophenolate, the patient’s medications included aspirin, insulin, itraconazole (for anti-fungal prophylaxis), levothyroxine, prednisone (tapering since transplant), and valganciclovir. The patient recently complained of rhinorrhea and cough productive of brown-tinged sputum, improving over the previous 2 weeks; she denied fever, chills, shortness of breath, night sweats chest pain, or gastrointestinal symptoms.

Physical examination showed the patient to be afebrile with normal heart and respiratory rates and blood pressure. Her room air oxygen saturation was 99%.

The patient’s complete blood count and serum chemistries showed largely normal values, with the white blood cell count at the upper normal at 9.7 x 10⁹ /L (normal, 4-10 x 10⁹ /L). Her liver function testing and renal function testing parameters were also within normal limits. Echocardiography showed normal left ventricular systolic function. The patient underwent frontal chest radiography (Figure 1).

Clinical History: A 79-year-old man with a past medical history significant for mild, intermittent asthma since childhood and mild aortic stenosis presents to the Emergency Room with fevers and chills for 5 days, associated with dry cough and dyspnea on exertion. His past medical history was otherwise relatively unremarkable, with coronary artery disease as evidenced by coronary artery calcium at a calcium scoring CT, hypothyroidism, and dyslipidemia. The patient has allergies to dust and penicillin, and his only medications included thyroid replacement, aspirin, and an albuterol inhaler as needed. He was a 15-pack-year smoker, quitting 30 years ago. His past surgical history was remarkable only for tonsillectomy, inguinal hernia repair, meniscal repair, and sigmoid colon resection for diverticular abscess 14 years earlier. The patient was afebrile, his heart rate was 96 beats / minute and regular, decreased breath sounds at the lung bases was noted, and the white blood cell count was normal. Electrocardiography showed no abnormalities. Oxygen saturation was 92% on room air. Frontal chest radiography (Figures 1A and B) was performed.

Figure 1. Frontal (A) and lateral (B) chest radiography.

Which of the following represents the most accurate assessment of the frontal chest imaging findings? (Click on the correct answer to proceed to the second of nineteen pages)

1. Chest frontal imaging shows bilateral pleural fluid collections
2. Chest radiography shows bilateral lower lobe bronchial wall thickening and patchy consolidation
3. Chest radiography shows cavitary lung disease
