Bilateral sciatic neuropathy as a complication of craniotomy performed in the sitting position: localization of nerve injury by using magnetic resonance imaging.

INTRODUCTION: Sciatic neuropathy is a rare but serious complication following surgery performed in the sitting position. METHODS: We report a case of a 12-year-old boy who developed bilateral sciatic neuropathy after a 9-h-long craniotomy while in the sitting position. RESULTS: Magnetic resonance imaging for the lower extremities revealed bilateral swelling of the sciatic nerves near the ischial tuberosities. CONCLUSION: A heightened awareness of sciatic nerve injury during prolonged surgery in the sitting position may make early diagnosis possible and allow prevention of further neurologic injury.
