Abstract

Meralgia paresthetica (MP) is a benign entrapment neuropathy which is characterized by sensory impairment and paresthesia in the cutaneous distribution of the lateral femoral cutaneous nerve. A 79-year-old woman presented with intermittent right inguinal burning sensation. The sensory nerve conduction study (NCS) showed decreased right side sensory nerve action potential (SNAP) on lateral femoral cutaneous nerve compared to the contralateral one. Abdomino-pelvic CT showed bilateral huge renal cysts (The size of largest one on right side: about $6.2{\times}5.0cm$). We report a case of MP caused by a huge abdominal renal cyst, which should be considered when conventional examination reveals no responsible etiology.
