Spontaneous spinal subdural hematoma is a rare disease. Several predisposing factors are reported including impaired clotting due to therapeutic anticoagulation or hematologic disorder, vascular anomaly, intraspinal tumor, and iatrogenic causes such as lumbar puncture or spinal anesthesia.We report a rare case of spontaneous spinal subdural hematoma developed after weightlifting in a healthy young man treated with conservative treatment.

A forty-one-year-old man who, sought evaluation for a sudden hip flexion contracture and groin pain with a history of mechanical mitral valve replacement, had been misdiagnosed and treated as having lumbar discopathy for two days. This patient finally was diagnosed with compressive femoral neuropathy due to warfarin-induced retroperitoneal hematoma and successfully managed nonoperatively. This case is reported in order to draw attention to this rare presentation.
