Carcinoma arising in urinary bladder diverticula: imaging findings in six patients.

Objective: Carcinoma arising within urinary bladder diverticula has a poorer prognosis than do neoplasms that originate within the main bladder lumen as a result of early transmural tumor infiltration. Imaging plays an important role in diagnosing and staging the disease. We describe the radiologic findings in six patients with pathologically proved diverticular carcinomas.

Disappearing breast calcifications: mammographic-pathologic discrepancy due to calcium oxalate.

We have reported a case in which breast biopsy was done to study suggestive microcalcifications that were confirmed by specimen radiography but were not evident with standard light microscopy. Examination of the specimen under polarized light revealed calcium oxalate crystals. Awareness of this potential pitfall should minimize the number of radiologic-pathologic discrepancies.

Diffuse lung uptake of technetium-99m sulfur colloid associated with fatty liver disease of pregnancy.

Diffuse pulmonary uptake of sulfur colloid was seen in a 35-year-old postpartum white female with the presumptive diagnosis of fatty liver disease of pregnancy. As the disease process resolved, the pulmonary uptake of sulfur colloid disappeared. To the authors' knowledge, this scan association has not been previously reported.
