ABSTRACT
Compressive femoral neuropathy is a disabling condition accompanied by difficulty in hip flexion and knee extension. It may result from retroperitoneal hematoma or bleeding, or from complications associated with pelvic, hip surgery, and renal transplants. A 55-year-old female with autosomal dominant polycystic kidney disease presented with proximal muscle weakness in lower extremities. The patient experienced recurrent renal cyst infection, with aggravated weakness during each event. Electromyography and nerve conduction study revealed bilateral femoral neuropathy. Computed tomography and magnetic resonance images were added to further identify the cause. As a result, a diagnosis of femoral neuropathy caused by enlarged polycystic kidney was made. Cyst infection was managed with antibiotics. Renal function was maintained by frequent regular hemodialysis. While avoiding activities that may increase abdominal pressure, rehabilitation exercises were provided. Motor strength in hip flexion and knee extension improved, and was confirmed via electrodiagnostic studies.
