title: Spinal hemangioblastoma combined with pilocytic astrocytoma.
abstract: The combination of vascular anomalies with gliomas is rarely seen in the CNS, and is defined as "angioglioma". However, the definition, category, and histopathogenesis of angiogliomas remain controversial. Here, we present an unusual case of spinal hemangioblastoma (HB) combined with pilocytic astrocytoma (PA). Spinal MRI revealed lesions extending from T9 to T12 segments, in a "sandwich-like" fashion. After resection of the tumor, histopathologic study confirmed the diagnosis of HB as well as PA. A comprehensive review of the literature was further conducted. We describe a case of spinal HB combined with PA, in addition we discuss the clinicopathological relationship between HB and PA under these conditions, which may facilitate the understanding of the histogenesis of an angioglioma and guide its diagnosis and treatment.
