Abstract

Spontaneous femoral neuropathy rarely occurs in young, healthy men. Herein, we present the first reported case of bilateral spontaneous femoral neuropathy. A 25-year-old man was admitted to the neuropsychiatric inpatient clinic with drug intoxication and showed bilateral knee extensor weakness. He had taken medication for several years for depression. He took an overdose of medication due to severe stress at the army recruit training center for beginning military service. He had slept for over 24 hours. After waking up, bilateral lower extremity weakness had developed. Magnetic resonance imaging showed a small hematoma between the left psoas and quadratus lumborum muscles, and signal intensity changes in the left femoral nerve–innervated muscles. An electrodiagnostic study demonstrated bilateral femoral neuropathy with axonal injury. Two months later, his weakness had partially recovered, and a follow-up examination revealed partial electrodiagnostic recovery. At a long-term third follow-up visit, both symptoms and electrodiagnostic findings had improved.
