Cases of lateral ventricular ectopic schwannomas (LVES) are extremely rare, with only 23 cases reported thus far. This study aimed to obtain a better understanding of the disease.
We reported a rare case of LVES, in which the patient was admitted to our hospital, and reviewed the relevant literature on LVES to summarize and analyze the clinical manifestations, pathologies, imaging features and progress.
Of the 23 patients, LVES was more common in men (74%, 17/23) than in women and was mostly located on the right side (78%, 18/23). The average age at clinical presentation was 28 years, with an age range between 8 and 68 years. Moreover, most cases were histologically benign, except in one case of malignancy. In all the benign cases, there were 2 cases of subtotal resection, but no recurrence was found during follow-up.
The origin of LVES could be the tumor transformation of autonomic nerve tissue in the perivascular choroid plexus. For lateral ventricle tumors,which are rare benign lesions with good prognosis after surgical resection, LVES should be considered in the differential diagnosis. Moreover, whether LVES could be considered for gamma knife treatment, similar to a small acoustic neuromas,requires further investigation.
侧脑室异位神经鞘瘤（LVES）病例极为罕见，迄今为止仅报道了23例。本研究旨在更好地了解该疾病。
我们报告了1例罕见的LVES病例，该患者入住我院，并复习了LVES的相关文献，以总结和分析其临床表现、病理、影像学特征及进展。
23例患者中，LVES在男性中更为常见（74%，17/23），女性较少，且大多位于右侧（78%，18/23）。临床表现的平均年龄为28岁，年龄范围在8至68岁之间。此外，除1例恶性病例外，大多数病例组织学上为良性。在所有良性病例中，2例次全切除，随访期间未发现复发。
LVES的起源可能是血管周围脉络丛自主神经组织的肿瘤转化。对于侧脑室肿瘤，这是一种罕见的良性病变，手术切除后预后良好，在鉴别诊断中应考虑LVES。此外，LVES是否可像小型听神经瘤一样考虑伽玛刀治疗，需要进一步研究。
