Abstract

A 17-year-old male patient complained of acutely developed severe paresthesia, pain, and weakness of the right lower extremity. He fell to the ground during performance of hand-stand physical exercise. Despite administration of conservative treatment for two weeks in a private clinic, motor function of the hip flexor and knee extensor were measured as poor grade. EMG showed femoral nerve and lateral femoral cutaneous nerve injury. Findings on MRI and CT revealed a mass measuring 8x5x7 cm in the iliac fossa. After evacuation of the hematoma(400 cc), neurologic dysfunction and thigh circumference were fully recovered, compared with the contralateral side, after one and half year follow up. This condition rarely occurs in individuals without coagulopathy. We reported on a rare case of iliacus hematoma and femoral neuropathy treated by surgical decompression in a patient with no coagulopathy.
