Case: A 45 year-old woman presented with an obturator nerve schwannoma (ONS), which was originally suspected to be a gynecologic malignancy. After thorough workup, the mass and obturator nerve were resected en bloc, and sural nerve grafting was performed. The patient had minimal deficits with return to baseline activities by 7 weeks postoperatively. Conclusion: We guide the reader through the challenging diagnosis of ONS, which may mimic many other intrapelvic masses. The treatment decision of whether to acutely reconstruct the obturator nerve is also discussed, along with implications and functional importance of the nerve in gait and hip motion.
Apel et al. (Thu,) studied this question.
