Imaging
Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary, Critical Care & Sleep publishes case-based articles with characteristic chest imaging and related pathology.
The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Week: Esophageal Cancer

Figure 1. Admission chest x-ray showing hyper-aerated lung fields and consolidation at the left lung base.
Figure 2. Video of selected images from thoracic CT scan in soft tissue windows showing large mediastinal mass with extravasation of contrast.
Figure 3. Views from endoscopy showing a large mass and the perforation site.
A 66-year-old Asian man with no significant past medical history was admitted with 1 week history of worsening retrosternal sharp chest pain, dyspnea on moderate exertion, and cough productive of brownish sputum. He also complained of some difficulty swallowing, decreased appetite and weight loss for the past 3 months. PPD was negative in the past. Vitals signs were significant for tachycardia and low grade fever. On physical exam he was cachectic and lung auscultation revealed bilateral scattered wheezes. Basic labs including complete blood count and comprehensive metabolic panel were unremarkable. EKG showed sinus tachycardia, serial troponin I was negative and chest x-ray revealed bilateral hyper-aerated lung fields and consolidation over the left lung base (Figure 1). He was started on antibiotics and bronchodilators. Since he continued to have chest pain and remained tachycardic, CT angiography of chest and abdomen (with IV and oral contrast) was done which revealed extravasation of contrast material into the mediastinum in the mid esophageal region representing rupture, a large mediastinal mass concerning for an abscess, and extensive infiltrates in the left lower lobe (Figure 2). During left thoracotomy, a large amount of necrotic material and phlegmon was seen in the mediastinum with adjacent area of lung necrosis which was drained and debrided. Upper GI endoscopy revealed a large mass in the mid-esophagus with perforation for which stenting was done (Figure 3). Pathology of phlegmon revealed squamous cell carcinoma with extensive necrosis. Culture of the fluid grew both viridians streptococci and anaerobes and he was started on broad spectrum antibiotics. His post-operative course was complicated and later he elected hospice care.

May 2013 Imaging Case of the Month
Michael B. Gotway, MD
Department of Radiology
Mayo Clinic Arizona
Scottsdale, AZ
Clinical History
A 21-year-old woman presented with complaints of cough. Frontal and lateral chest radiography (Figures 1A & B) was performed. A detail comparison chest radiograph from several years prior (Figure 1C) is presented as well.
Figure 1. Frontal (A) and lateral (B) chest radiography at presentation and a radiograph from several years earlier (C).
Which of the following statements regarding the chest radiograph is most accurate?
- The chest radiograph predominantly shows bilateral linear and reticular abnormalities
- The chest radiograph shows a combination of nodules, masses and thin-walled cysts
- The chest radiograph shows multifocal consolidation with air bronchograms
- The chest radiograph shows multifocal pleural abnormalities
- The chest radiograph shows mediastinal widening & hilar lymphadenopathy
