The Performance of Radiographic Criteria for Bone Malignancy When Applied to Computed Tomography and Magnetic Resonance Imaging.

Background: The conventional radiologic features that differentiate benign from malignant bone lesions were originally described using radiography (x-ray [XR]). When evaluating sectional imaging studies such as magnetic resonance imaging (MRI) and computed tomography (CT), one may apply these principles to identify malignant bone lesions. The aim of this study was to evaluate the performances of these radiographic features for detecting malignity when applied to CT and MRI.

Unusual magnetic resonance image of an insulinoma with extensive desmoplastic reaction.

Context: Unlike other islet-cell tumors, insulinomas are usually benign. Most insulinomas have a high signal intensity on T2-weighted images and a low signal intensity on T1-weighted images, and are hyperintense on immediate post-gadolinium images. However, in rare cases, insulinomas may be hypointense on T2-weighted images and on immediate post-gadolinium images, mimicking a ductal adenocarcinoma.

Colitis cystica profunda (CCP) is an uncommon benign condition characterized by mucin-filled cysts located in the submucosa, frequently associated with the solitary ulcer and rectal prolapse syndromes. The diagnosis of this entity is important as it can mimic rectal cancer and therefore may result in unnecessary surgical resection. Endoscopic examination and barium enema findings are suggestive but not specific, neither are superficial biopsy findings.
