Paragangliomas are rare tumors that arise from the extraadrenal chromaffin cells. We report here on a case of retroperitoneal paraganglioma in a 24-year-old young man. Abdomen CT and magnetic resonance imaging showed a hypervascular mass near the left ureter. He had not felt paroxysmal palpitation and his vital signs were within the normal range. An exploratory laparotomy revealed a 7.2×5.5 cm sized mass below the jejunum and near the aorta, and this mass had adhesion to the left ureter. It was histologically diagnosed with a paraganglioma after the surgical resection. Although there was an increase of blood pressure on palpation during surgery, the postoperative course was uneventful. When we consider the unusual locations and the associated operative risk, we should take care to rule out the possibility of a functional paraganglioma in the preoperative differential diagnosis of an abdominal mass.

We retospectively analyzed mammographic changes after excision biopsy in patients with benign breast diseases. We evaluated follow-up mammograms of 30 cases in 22 patients who confirmed as benign breast disease, pathologically. The age distribution of the patients was 29 years in the youngest and 71 years old in the oldest(mean: 45.3). The intervals between pre-biopsy mammography and post-biopsy follow up study was 20 days to 31 months(mean: 286 days). The pathologic diagnosis of the cases were 11 fibrocystic disease patient(50%), 4 adenosis (18.2%), 3 atypical intraductal papillomatosis (8.2%) and I case of atypical ductal hyperplasia, atypical lobular hyperplasia, atrophic breast tissue, fibroadipose tissue and fibrosis. On follow-up mammographies, 15 cases(68.2%) shouled parenchymal changes such as focally increased density, architectural distorsoin, parenchymal retraction, spiculated density 10 cases(45.5%), skin changes such as retraction or thickening but 4 cases did not show any discernible abnormality. Among cases showing parenchymal changes, 6 cases showed different configuration on different projection, which suggesting benign lesion rather than breast cancer. It was suggested that the mammographic findings after excision biopsy in benign diseases be considerably variable, and to know these findings and history of biopsy seem to be mandatory in interpretation of post-biopsy mammograms.
