Large schwannoma of the sciatic nerve

Description

A 40-year-old woman was referred with an 8-month history of fullness of the right posterior thigh. This was associated with pain, primarily on sitting and occasional radicular pain down the ipsilateral leg. On examination a mobile, firm lump was identified that was tender to palpate and which also elicited a shooting pain down the leg on examination. MRI demonstrated a well-defined multiloculated mass 9 cmsx6 cms which appeared to arise from the sciatic nerve, raising suspicion for a schwannoma (figure 1). A biopsy confirmed the diagnosis of schwannoma. Surgical excision was undertaken, carefully dissecting the lesion from the sciatic nerve (figure 2). The patient had an uneventful postoperative recovery without neurovascular deficits.
