Abstract Sciatic schwannomas (SSs) are extremely rare, and most are benign. Herein, we report a case of giant SSs in a woman who presented with abdominal pain. Because of the pain pattern and auxiliary examination findings, the patient was initially diagnosed with an ovarian cystadenoma. Magnetic resonance imaging (MRI) revealed an intrapelvic tumor. Histopathological examination confirmed that the mass was a benign intrapelvic schwannoma. Two days after complete tumor resection, the patients experience impaired mobility of the right lower limb. The tumor was 7 × 5.5 × 5 cm 3 in size and in contact with the sacrum. The patient was followed up for up to 2 years. No evidence of recurrence was observed in the MRI scan. Severe damages to the sciatic nerve during surgery resulted in permanent neurological deficits. Hence, we also discuss the diagnostic tools and treatments for intrapelvic SSs, as well as the importance of careful radiological examination and multidisciplinary collaboration.
