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: Right Neck Mass with Thoracic Extension
Figure 1. Coronal MRI image showing cavitary lesion (1.9 cm, yellow arrow) in the right lower lobe and multiple enlarged mediastinal and hilar lymph nodes with the largest lymph node measuri 2 x 2.5 cm.
Figure 2. Coronal MRI image of neck showing ill-defined infiltrative mass (2.8 x 4.1 x 6.4 cm, yellow star) in the right lateral neck posterior to the sternocleidomastoid muscle and jugular vein.
Figure 3. Right upper lobe endobronchial lesion (yellow arrow). Biopsy showed Coccidioides spherules.
Figure 4. Hematoxylin and eosin (upper panel) and Gomori's methenamine silver stain stains of 4R lymph node showing Coccidioides spherule.
A 28-year-old female with a history of chronic pancreatitis s/p total pancreatectomy and auto-islet cell transplantation developed a progressively enlarging right neck mass of 4 weeks duration. Coccidioides IgM antibodies were negative and IgG antibodies were positive by immunoassay (EIA), with titers 1:4 by complement fixation (CF). Fine needle aspiration with subsequent excisional biopsy of the right neck mass was performed and showed reactive lymphoid hyperplasia without fungal elements. Bronchoscopy with right upper lobe endobronchial biopsy and 4R lymph node endobronchial ultrasound-fine needle aspiration revealed granulomatous inflammation and Coccidioides spherules on Gomori's methenamine silver stain. Fungal cultures from the right neck mass fine needle aspiration, endobronchial biopsy, and 4R lymph node grew Coccidioides after three weeks of culture.
