Granular cell tumor is a rare and usually benign tumor that occasionally involves the breast. The physical examination, the mammographic and ultrasonographic findings and the pathologic findings are often suggestive of carcinoma. We report here a rare case of granular cell tumor of the breast that mimicked carcinoma on the mammography, ultrasonography and MR imaging.

Concurrent occurrence of an adenocarcinoma and carcinoid tumor in the stomach has been observed infrequently; moreover, a gastric collision tumor of both tumor types has rarely been seen. We describe a case of a gastric collision tumor following the differential diagnosis from observing the morphological patterns more closely using CT gastrography. The patient presented with a gastric collision tumor that consisted of an adenocarcinoma and carcinoid tumor in the antrum of the stomach.

OBJECTIVE: We prospectively compared whole-body multidetector computed tomography (MDCT) and 3.0T magnetic resonance (MR) images with autopsy findings. MATERIALS AND METHODS: Five cadavers were subjected to whole-body, 16-channel MDCT and 3.0T MR imaging within two hours before an autopsy. A radiologist classified the MDCT and 3.0T MRI findings into major and minor findings, which were compared with autopsy findings. RESULTS: Most of the imaging findings, pertaining to head and neck, heart and vascular, chest, abdomen, spine, and musculoskeletal lesions, corresponded to autopsy findings. The causes of death that were determined on the bases of MDCT and 3.0T MRI findings were consistent with the autopsy findings in four of five cases. CT was useful in diagnosing fatal hemorrhage and pneumothorax, as well as determining the shapes and characteristics of the fractures and the direction of external force. MRI was effective in evaluating and tracing the route of a metallic object, soft tissue lesions, chronicity of hemorrhage, and bone bruises. CONCLUSION: A postmortem MDCT combined with MRI is a potentially powerful tool, providing noninvasive and objective measurements for forensic investigations.
