Schwannoma in the retroperitoneum

Journal of Obstetrics and Gynaecology Research, 2007
AbstractSchwannoma (neurilemmoma) is a peripheral nerve sheath tumor and commonly occurs singularly on the head, neck, and trunk. Giant schwannoma is rarely located on the retroperitoneum and pelvic cavity. The majority of symptoms caused by the tumor are due to the effect of its mass. Surgical resection is enough to treat the tumor.
