Abstract
Purpose: The purpose of this study was to review the clinical characteristics and treatment strategies of patients with retroperitoneal schwannomas adjacent to important abdominal vessels.Case Presentation: A total of three patients with retroperitoneal schwannoma immediately adjacent to important blood vessels in the abdominal cavity underwent successful surgical resection. They all had symptoms of abdominal pain and discomfort, two cases underwent three-dimensional reconstruction. There were no serious complications such as peripheral blood vessels and organ damage in all three cases. One case had chyle leakage after surgery, conservative treatment was successfully discharged.Conclusions: Retroperitoneal schwannomas immediately adjacent to important abdominal vessels have unique clinical characteristics. Preoperative three-dimensional reconstruction can fully show the local vascular relationship of the tumor, which is conducive to surgical planning and risk assessment. Benign tumors with large size and adjacent complex vessels can still be completely resected by surgery. Laparotomy resection is safe and feasible.
Highlights
Retroperitoneal schwannoma is a rare clinical entity, accounting for only 1% of all retroperitoneal tumors [1]. They are soft tissue tumors and originate from Schwann cells in the peripheral nerve capsule. When they are closely adjacent to blood vessels, the tumor may originate from the blood vessel wall, to be precise, from the peripheral nerve fibers on the adventitia of the blood vessel wall [2]
It should be considered tumors that compress blood vessels may themselves originate from blood vessels, because this is critical to the choice of treatment options
We report three cases whose retroperitoneal schwannomas adjacent to important abdominal vessels were completely removed to provide clinicians with experience in diagnosis and treatment
Summary
Retroperitoneal schwannoma is a rare clinical entity, accounting for only 1% of all retroperitoneal tumors [1]. They are soft tissue tumors and originate from Schwann cells in the peripheral nerve capsule. It should be considered tumors that compress blood vessels may themselves originate from blood vessels, because this is critical to the choice of treatment options. They are usually benign, accounting for nearly 8% of retroperitoneal benign tumors [3], and malignancy is rare. Schwannomas usually occur in the peripheral nerves of the head, neck or limbs, only 0.5–5%
