Abstract

Background: Intracerebral schwannoma is an extremely rare disease, accounting for fewer than 1% of intracranial schwannomas. The most common site for this type of schwannoma is the cerebral hemisphere, especially the frontal and temporal lobes; brainstem schwannoma is infrequent. Case Description: Here, we report a 51-year-old man with a monthlong history of blurred vision and weakness in his left lower limb. Magnetic resonance imaging showed a heterogeneous cystic tumor with a solid nodule arising from the brainstem. The patient underwent a craniotomy with complete resection of the tumor, which was confirmed to be a brainstem schwannoma by histopathological examination. We also performed a literature review of the 19 reported cases of brainstem schwannoma. Conclusions: Brainstem schwannomas predominated in children and young adults (60% of cases occurred in patients ≤ 30 years of age), and were more common in females (65%). Most of these schwannomas exhibited heterogeneous intensity, containing cystic (78%) and solid-enhanced components. The vast majority of reported cases (94.9%) followed a benign course, with an improved prognosis following tumor resection.
脑干神经鞘瘤1例报告及临床和影像学特征回顾
背景:脑内神经鞘瘤是一种极为罕见的疾病,占颅内神经鞘瘤的不到1%。这种类型的神经鞘瘤最常见的部位是大脑半球,尤其是额叶和颞叶;脑干神经鞘瘤并不常见。病例描述:在此,我们报告一位51岁的男性,他有一个月的视力模糊和左下肢无力的病史。磁共振成像显示脑干的非均匀囊性肿瘤伴实性结节。患者行开颅手术并完全切除肿瘤,经组织病理学检查证实为脑干神经鞘瘤。我们也对19例脑干神经鞘瘤的报道进行了文献回顾。结论:脑干神经鞘瘤以儿童和青壮年为主(60%的病例发生在≤30岁的患者中),在女性中更为常见(65%)。大多数神经鞘瘤表现出不均匀的强度,包含囊性(78%)和固体增强成分。绝大多数报告病例(94.9%)为良性病程,肿瘤切除后预后改善。
