Abstract

Compressive femoral and lateral femoral cutaneous neuropathies from an iliacus hematoma are unusual presentation. We report a case of a 16-year-old boy who developed right femoral and lateral femoral cutaneous neuropathies as a complication of traumatic ipsilateral iliacus hematoma formation. The patient complained of numbness in the right thigh and calf as well as right leg weakness, and pain in the right inguinal area. Nerve conduction study and needle electromyography identified the neuropathies. After the electrodiagnostic studies, the pelvic bone MRI revealed a large, 9x5x4.5 cm right iliacus hematoma. As a result, diagnosis of a right iliacus hematoma compressing the femoral and lateral femoral cutaneous nerves was made, and the patient underwent an operation to remove the hematoma. Symptoms and neurological signs showed notable improvement after surgical decompression. Subsequent follow-up electrodiagnostic studies after 11 weeks demonstrated regeneration evidence.
