Lipoastrocytoma: A case report

Abstract

Lipidized tumours of the central nervous system are very rare. Lipidization of tumour cells is a histological hallmark of pleomorphic xanthoastrocytoma and cerebellar neurolipocytoma and has been described in some other primary neuroepithelial tumours such as glioblastoma, cerebral primitive neuroectodermal tumour, central neurocytoma and ependymoma. However, a few cases of lipidized low-grade glial tumours that could not be classified to the fore mentioned categories have been reported, as well. We report a new case of such a tumour occupying the right temporal lobe in a 23-year old woman. Histologically, the tumour was composed of GFAP positive glial cells with areas of complete cell lipidization. More than a two years after the surgery, the patient is well and asymptomatic supporting presumed favourable clinical course of these rare tumours. The recommended treatment plan for these presumably benignant tumours should be continued with radiographic surveillance after the gross total resection. © Versita Sp. z o.o.
