title: Deep renal ectopia causing sciatic mononeuropathy.
abstract: BACKGROUND
  Sciatic mononeuropathy resulting from compression by an adjacent pelvic ectopic kidney has not been reported in the literature. Here, the authors present a case of a patient presenting with unilateral lower extremity paresthesia correlating to the sciatic nerve distribution.
  
  
  RESULTS
  MRI examination demonstrated lumbosacral plexus compression by a very unusual deeply situated renal ectopia. Physicians should consider other rare causes of mechanical lumbosacral plexus compression in patients with sciatic symptomatology.
