Abstract:
PURPOSE: To evaluate the imaging findings of abdominal extraosseous plasma cell neoplasm. MATERIALS AND METHODS: From April 2000 to January 2005, eight patients (four men, four women; mean age, 50.6 years) with pathologically proved, extraosseous plasma cell neoplasm involving the abdominal organs were included in this study. The diagnoses were based on consensus agreement between two radiologists who retrospectively reviewed CT, ultrasonography, and enteroclysis findings. We evaluated the findings by focusing on the location, size, margin, and enhancement pattern of the lesion, and lymphadenopathy on each image. RESULTS: There were multiple myeloma in four patients and extramedullary plasmacytoma in the remaining four. Involved abdominal organs were the liver (n = 4), spleen (n = 4), lymph node (n = 3), stomach (n = 1), small bowel (n = 1), and colon (n = 1). The hepatic involvement of plasma cell neoplasm presented as a homogeneous, well-defined, solitary mass (n = 1), multiple nodules (n = 1), and hepatomegaly (n = 2). Its involvement of the spleen and lymph node appeared as splenomegaly and lymphadenopathy, respectively. Its involvement of the gastrointestinal tract including the stomach, small bowel, and colon, presented as a homogeneous, diffuse wall thickening or mass in the gastrointestinal tract. CONCLUSION: Abdominal extraosseous plasma cell neoplasm involves occasionally the liver, spleen, and lymph node, and rarely the gastrointestinal tract. When we encounter a well-defined, homogeneous lesion of the abdominal organs in patients diagnosed or suspected as having plasma cell neoplasm, we should consider its involvement of the abdominal organs.
