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: Chronic Bilateral Fibrocavitary Pulmonary Coccidioidomycosis
Figure 1. Chest x-ray showing bilateral upper lobe cavitation.
Figure 2. Thoracic computed tomography showed bilateral upper lobe, multiple thick-walled cavities with associated tree in bud opacities and consolidation in the right lower lobe.
Figure 3. Cytology of bronchoalveolar lavage fluid showing coccidioidomycosis spherules (arrows).
A 47-year-old Ethiopian immunocompetent male with no past medical history presented with cough and blood tinged sputum for 1 month with no fever, night sweats, or weight loss. Chest X-ray showed bilateral upper lobe cavitary lesions (Figure 1). Computed tomography of the chest showed bilateral upper lobe, multiple thick-walled cavities with associated tree-in-bud opacities and consolidation in the right lower lobe (Figure 2). TB was ruled out and a bronchoalveolar lavage (BAL) was performed. Cytology on the BAL showed the presence of Coccidioides immitis spherules (Figure 3). Serum coccidioidomycosis by complement fixation 1:64 with positive IgG by immunodiffusion; serum antigen by EIA 0.30; and urine antigen was negative. The patient was started on fluconazole and was discharged with pulmonology follow up. Bilateral cavitary lesions are rare and they can mimic the reactivation of M. tuberculosis, reinforcing the importance of including coccidioidomycosis in the differential diagnosis of bilateral cavitary lung lesions for patients in endemic areas.
