RADIOLOGY: GASTROINTESTINAL: GI: Case# 33014: ?DERMOID, FAMALIAL POLYPOSIS. 22-year-old woman with prior history of familial polyposis and left hemicolectomy. There is some question as to the presence of malignancy in the histologic specimen. This procedure was performed 5 years ago. There is a suggestion of small bowel obstruction clinically. There is moderate right-sided hydroureteronephrosis. The ureter is dilated to approximately the pelvic inlet. At this location, there is a large mass measuring over 6.0 cm in diameter. In the left mid and lower abdomen, what appear to be numerous loops of bowel, the interpretation is somewhat hampered by the near complete absence of intra-abdominal fat and the absence of orally administered contrast material. There is no evidence of bowel dilation.
