History of present illness

A 31-year-old male fire fighter with a history of recurrent “atypical pneumonia”, environmental and drug allergies, nasal polyps, asthma, and Crohns disease (not on immunosuppressants) was transferred from an outside hospital for management of acute hypoxic respiratory failure with peripheral eosinophilia. Prior to admission he reported a 2-week history of worsening dyspnea, productive cough and wheezing, prompting an urgent care visit where he was prescribed amoxicillin-clavulanate for suspected community acquired pneumonia. Despite multiple days on this medication, his symptoms significantly worsened until he was unable to lie flat without coughing or wheezing. He was ultimately admitted to an outside hospital where his labs were notable for a leukocytosis to 22,000 and peripheral eosinophilia with an absolute eosinophil count of 9700 cells/microL. His blood cultures and urine cultures were negative, and a radiograph of the chest demonstrated bilateral nodular infiltrates. With these imaging findings combined with the peripheral eosinophilia there was a concern for Coccidioidomycosis infection and he was subsequentially started on empirical fluconazole in addition to ceftriaxone and azithromycin. Bronchoalveolar lavage (BAL) was performed revealing 80% eosinophils, 14% polymorphic nuclear cells (PMNs), 4% monocytes and 2% lymphocytes, no pathogens were identified. The patient’s clinical status continued to decline despite antimicrobial therapy, and he was intubated for refractory hypoxia. At this point, the patient was transferred to our hospital for further care.

2. Will be better able to establsh the optimal evaluation leading to a correct diagnosis for patients with pulmonary, critical care and sleep disorders.
3. Will improve the translation of the most current clinical information into the delivery of high quality care for patients.
4. Will integrate new treatment options in discussing available treatment alternatives for patients with pulmonary, critical care and sleep related disorders.

Learning Format: Case-based, interactive online course, including mandatory assessment questions (number of questions varies by case). Please also read the Technical Requirements.

History of Present Illness

Our patient is a 76-year-old gentleman  who was referred based on an abnormal CT scan. He has a history of metastatic melanoma and had begun immunotherapy with pembrolizumab 10 months prior to admission. He had low grade fevers and chills and some dyspnea on exertion and dry cough. He also had a 6-8 pound weight loss over 4 weeks.

PMH, SH and FH

He has a history of hairy cell leukemia since 2009; squamous and basal cell cancers; and diabetes on insulin. He is a retired commercial banker and has a 15 pack-year smoking history.

Physical Examination

Physical examination showed and SpO2 of 90% on room air. His lungs were clear. He had numerous depigmented lesions on his skin.

Radiography

A thoracic CT scan was performed (Figure 1) and compared to a scan done 3 months prior which was considered unremarkable.

Which of the following best describe the CT scan? (Click on the correct answer to proceed to the second of four pages)

1. Normal
2. Mosaic pattern of lung attenuation
3. Numerous bronchial-associated ground glass opacities
