An Unusual Cause Of Acute Atraumatic Hip Pain - Page #4

Working Diagnosis:
Lipoma with cutaneous sensory nerve entrapment.

General surgery excised the lipoma.

One week post-surgically, his pain was greatly improved. By two weeks post-op, his pain had completely resolved. He was cleared to return to hunting without restrictions.

Editor's Comments:
Lipomas are a very common tumor but infrequently cause nerve compression symptoms. (3)
The clinical picture is often similar to entrapment neuropathy. (1)
Ultrasound imaging is useful to define the mass as a nonneural sheath origin tumor; MRI allows a better analysis of the relationship of the tumor with other structures. (1)
Surgical treatment offers good outcomes in pain relief and neurological recovery. (1)
