摘要

脑膜播散是一种罕见的朝粒细胞星形细胞瘤表现。髓母细胞瘤、上皮瘤和高级别胶质瘤等高级别肿瘤可能会出现这种情况，但低级别胶质瘤则极为罕见。在医学文献中，有越来越多的病例报告记录了绒毛细胞性星形细胞瘤的脑膜播散：描述了一例世界卫生组织（WHO）I级星状上皮细胞星形细胞瘤伴有脑和脊髓的脑膜外播散，长期随访显示脑膜外结节进展，但肿瘤没有升级。

Suprasellar pilocytic astrocytoma with leptomeningeal dissemination.

Leptomeningeal dissemination is a rare manifestation of pilocytic astrocytoma. It may occur with higher-grade tumours like medulloblastoma, ependymoma and high-grade glioma, but is extremely rare with low-grade glioma. There has been a growing number of reported cases documenting leptomeningeal dissemination of pilocytic astrocytoma in the medical literature.

Contribution: Description of a World Health Organization (WHO) Grade I suprasellar pilocytic astrocytoma with leptomeningeal dissemination in the brain and spinal cord which showed progression of the leptomeningeal nodules without tumour upgrading on long-term follow-up.
