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 Month: Emphysematous Cystitis
Figure 1. Abdominal CT with contrast showing a thickened, trabeculated bladder wall containing pockets of gas consistent with emphysematous cystitis due to E. coli infection.
Emphysematous cystitis is a rare infection of the urinary bladder caused by gas producing organisms which can be bacterial or fungal characterized by gas collections inside the bladder wall (1). Most common organisms are E. coli, Klebsiella and Proteus are also commonly isolated. Fungi, such as Candida, have also been reported as causative organisms. Presentation range from asymptomatic up to septic shock.

Medical Image of the Week: Pancreatic Abscess
Figure 1. CT scan of the abdomen showing fluid collections (arrows).
Figure 2. Ultrasound of the abdomen showing a distended pancreatic duct, which communicates to an inferior fluid collection, likely a pseudo-cyst.
Figure 3. Coronal CT of the abdomen and pelvis showing pelvic abscess (arrow).
A 55 year old woman, with a history of alcohol abuse and necrotizing pancreatitis, was readmitted for worsening abdominal pain and acute respiratory failure. A CT scan of the abdomen and pelvis showed an atrophic pancreas and multiple fluid collections. Along the inferior surface of the pancreas, there is a fluid collection with an evolving loculated rim, which is asymmetric, the larger component measure 2.9 cm x 4.7 cm (Figure 1, large arrow). Anterior to the body of the pancreas, there is an additional 2.2 cm x 2.4 cm with evolving loculated rim (Figure 1, short arrow), both compatible with a pseudocyst. Ultrasound of the abdomen showed a distended pancreatic duct that communicates to the smaller fluid collection (Figure 2). Coronal CT of the abdomen and pelvis showed a 12.4 cm pelvic abscess (Figure 3). CT guided drainage of the pelvic abscess was performed with positive culture of the fluid for E. coli. She developed secondary peritonitis and had a successful exploratory laparotomy.
