title: Retroperitoneal granular cell tumor. Computed tomography findings with 5-year follow-up.
abstract: We describe the computed tomography (CT) appearance of an unusual, large retroperitoneal granular cell tumor and provide a 5-year follow-up. The tumor occurred in association with multiple, smaller, subcutaneous granular cell tumors. The CT findings were nonspecific, but the scans delineated the extent of the lesion and its relationship to adjacent vessels well. To our knowledge, this report is the first description of the CT appearance of retroperitoneal granular cell tumor in the medical literature.
