Abstract
Schwannoma is a type of tumor originating from Schwann cells of peripheral
nerves. In this study, we report a rare case of two giant connected
retroperitoneal schwannomas. The patient presented to our department with a
1-day history of abdominal pain and without other symptoms. There were no
abnormalities in the patient’s tumor markers. Abdominal plain computed
tomography (CT) revealed two (combined) retroperitoneal masses appearing as soft
tissue-density shadows with uneven internal density, cystic low-density shadows,
and patchy calcification shadows. The larger mass measured approximately
12.0 cm × 12.3 cm in size. The tumors were completely excised by a reasonable
surgical approach while the surrounding organs closely related to the tumor were
preserved. Postoperative pathology confirmed that the tumors were benign
schwannomas. In the 18-month follow-up, the patient had no recurrences and was
asymptomatic. We summarize the diagnosis and treatment of two rare combined
giant retroperitoneal schwannomas in a single patient. Laparotomy for the
management of retroperitoneal giant schwannomas may be safe and effective.
