Abstract

The following two cases represent unusual causes of coccygodynia that were initially believed to be functional in origin. (1) MRI showed an enhancing ovoid presacral soft tissue mass which was removed and identified as an epidermoid cyst. (2) Repeat abdomen/pelvis CT with oral and IV contrast revealed a 13 x 10 cm presacral mass. Sigmoidoscopy showed an area of extrinsic compression at the rectum. After removal the mass was identified as an Ewing's Sarcoma. It appears that CT scan with IV and rectal contrast may be of value when performing further radiological testing.
