Schwannoma is a tumor arising from Schwann's cells forming the neural sheath of peripheral nerves. Most common locations are cranial nerves (expecially the 8th pair) and in peripheral nerve system, neck, mediastinum and extremities. Abdominal location is very rare. The case of a 70 year-old woman presenting aspecific symptoms and a retroperitoneal peri-aortic mass is reported. The diagnosis and treatment are described. Abdominal and pelvic location as well as the retroperitoneal one are unusual and, when suspected, a differential diagnosis with other retroperitoneal neoplasms is necessary. The low frequency of this tumor and the lack of specific instrumental signs and objective symptoms make presurgical diagnosis very difficult. Surgical resection is the appropriate treatment and only after surgery and definitive histological examination the diagnosis can be confirmed. A regular follow-up is useful.
