Abstract

Intramuscular injections are probably the most common causes of sciatic nerve injury in developing countries. Piriformis syndrome, primary tumors of sciatic nerve, metastatic tumors invading or compressing the nerve, endometriosis, vascular malformations, prolonged immobilization or specific positions are rarer causes of sciatic neuropathy. Although the most reliable methods are nerve conduction studies and electromyography for diagnosis, and prognosis, magnetic resonance imaging is also suggested to be an alternative investigation method to determine the type of lesion, to establish its site and the level of nerve involvement.
Here, we present a case with sciatic neuropathy which developed after intramuscular injection during a prolonged lithotomy position under sedation.
