Review Case Reports
Abdominal imaging findings in gastrointestinal basidiobolomycosis.
To describe the abdominal imaging findings of patients with gastrointestinal Basidiobolus ranarum infection. ⋯ Radiologists should consider GIB when a patient from an arid climate presents with abdominal pain, weight loss, and an inflammatory abdominal mass on CT. Abdominal masses of the colon or liver, bowel wall thickening, and abscesses are the most common imaging findings.

Assess the utility of CT and MRI in patients with acute pancreatitis (AP) presenting to emergency department (ED). ⋯ Early imaging is common in patients with AP, even when the diagnosis can be established based on non-imaging criteria, rarely demonstrating pancreatic necrosis. Reducing overuse of early imaging in patients with confident diagnosis of AP may improve quality and reduce waste.

To assess the clinical benefit of 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (18F-FDG-PET/CT) in evaluating pelvic lymph nodes in patients with early stage cervical cancer (FIGO stage 1a–1b1), who have magnetic resonance imaging (MRI)-defined lymph node negative disease, with histopathologic results as the reference standard. ⋯ Pathologic validation of 18F-FDG-PET/CT imaging demonstrates little value for 18F-FDG-PET/CT in patients with early stage (FIGO stage 1a–1b1) MRI-defined lymph node negative cervical carcinoma. Since the likelihood of metastatic nodal disease is very low in women with stage 1a–1b1 cervical cancer, we believe that 18F-FDG-PET/CT should not have a role in the routine pre-treatment evaluation of these women.

To determine if transit time for excretion of gadoxetate into major bile ducts and duodenum correlates with clinical models of hepatocellular function. ⋯ The transit time for gadoxetate to appear in extrahepatic duct is a reasonable indicator of liver function, and may be included in radiology reports. The appearance in the duodenum, however, may depend on factors other than liver function, such as the physiology of the gallbladder and sphincter of Oddi.

Ketamine is a commonly abused recreational drug in Southeast Asia. There are emerging reports on ketamine abuse causing liver injury and biliary dilatation. This retrospective study aims to investigate the clinical and radiological features of this condition. ⋯ Ketamine-related cholangiopathy manifested as fusiform dilatation of the CBD without evidence of obstructive lesions. Severity of CBD dilatation appears to be correlated with the duration of ketamine, and the condition is potentially reversible in abstinent patients.
