Ventral exophytic growth of a spinal intramedullary glioma into the cranial cavity is an unusual condition.
A 16-year-old boy was admitted because of lower cranial nerve dysfunction and acute hydrocephalus. Magnetic resonance images showed an intramedullary mass lesion in the upper cervical spinal cord with exophytic extension into the medullary and prepontine cisterns. The patient underwent suboccipital craniectomy and C1-2 laminectomy for decompression and histologic evaluation. The histopathologic findings were characteristic of astrocytoma grade II. Although radiotherapy was performed, the patient died 7 months later.
This is considered to be a rare case of spinal low-grade astrocytoma with ventral exophytic intracranial extension.
脊髓髓内胶质瘤向颅腔腹侧外生性生长是一种罕见情况。
一名16岁男孩因低位颅神经功能障碍和急性脑积水入院。磁共振成像显示上颈段脊髓有髓内肿块病变，并向外生性延伸至延髓和脑桥前池。患者接受了枕下颅骨切除术和C1-2椎板切除术以进行减压和组织学评估。组织病理学检查结果为II级星形细胞瘤的特征。尽管进行了放疗，但患者7个月后死亡。
这被认为是一例罕见的伴有腹侧外生性颅内延伸的脊髓低级别星形细胞瘤病例。
