Cerebellar pleomorphic xanthoastrocytoma: case report and literature review.

Background: PXA generally has histologic features characteristic of benign biological behavior, although malignant forms have been reported. This neoplasm has also been observed in atypical locations.

Asymptomatic syringomyelia in the course of medulloblastoma.

Syringomyelia is frequently associated with Chiari malformation or one of many other pathological conditions. Its co-occurrence with medulloblastoma is rare, and to our knowledge, only 4 patients have been reported, although some reports have documented on syringomyelia associated with intracranial processes or intramedullary tumor. The authors describe an unusual case of asymptomatic thoracic syringomyelia complicated by an intrasyringal hemorrhage in a child with medulloblastoma.

Multicentric pleomorphic xanthoastrocytoma in a patient with neurofibromatosis type 1. Case report and review of the literature.

The authors report an unusual case of multicentric pleomorphic xanthoastrocytoma (PXA) in a 36-year-old woman with neurofibromatosis Type 1 (NF1). Both lesions were diagnosed as PXA but demonstrated different neuroimaging features and very different outcomes. Although the occipital lesion was cured surgically, the cerebellar tumor recurred three times and underwent malignant transformation into an anaplastic oligodendroglioma.
