Case Discussion

The patient was complaining from low back pain and coccydynia long time ago. Initially he was investigated by plain XR of the lumbosacral spine and coccyx. It suggested erosive lesion of the sacrum. After that the patient underwent pre and post contrast study of the lumboscaral spine and coccyx. It showed a definite sacrococcygeal destructive mass with a large soft tissue component that displaces the rectum.Lastly CT is requested with IV and transrectal contrast to assess the relation of the large associated presacral mass with the pelvic structures specially the rectum. We can also trace the median and two lateral sacral arteries, the main arterail supply of the mass to ensure good hemostasis during surgical intervention. After resection and histopathological examination, it is proved to be giant cell tumor of the sacrum.
