BACKGROUND
Schwannoma is a tumor arising from peripheral nerve sheaths and commonly occurs in the head, neck, and upper and lower extremities. Schwannoma in the presacral space is relatively rare and is often misdiagnosed before pathologic diagnosis is made.
CASE DESCRIPTION
Here we discuss a case of giant presacral schwannoma in a 34-year-old man with an emphasis on imaging findings.
CONCLUSIONS
Solid and encapsulated, round or oval, with rich blood supply may be the characteristic imaging findings of presacral schwannoma, which may narrow the differential diagnosis of hypervascular pelvic lesions.
背景
神经鞘瘤起源于外周神经鞘，常见于头颈部和上下肢。发生于骶前间隙的神经鞘瘤较为罕见，在病理诊断做出之前常被误诊。
病例描述
本文讨论了 1 例 34 岁男性的巨大骶前神经鞘瘤病例，重点介绍了影像学表现。
结论
骶前神经鞘瘤的特征性影像学表现为实性和包膜完整、圆形或椭圆形、富血供，这可能有助于缩小富血管性盆腔病变的鉴别诊断范围。
