Subject: Pelvic mass

Dear All,

A female 18 years old a year ago sustained high two column acetabular fracture treated by ORIF. 6 months later - no Trendelenburg, no limp, returned to work - a dancer in a gypsy ensemble.

A week ago suddenly marked pain in the limb, irradiation to the foot, numbness/paresthesia of the tibia, lumbalgia. Neurosurgeon examined her and found no pathology. Xrays of the pelvis and lumbar spine show nothing unexpected. CT scans revealed some volume in the pelvis

THX in advance.

Best regards,

It could be blood, pus, or a tumor. Do you have any more films?

Regarding case of large soft tissue mass in the pelvis 6 months after ORIF of acetabulum fracture. I would consider an ultrasound to see if it is solid or fluid filled and an MRI. It looks big and round and is suggestive of fluid. Keep in mind possible pseudo-aneurysm (careful about biopsy), or abscess. Soft tisssue neoplasia unrelated to the fracture possible.
