BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015213013 DESCRIPTION Pilocytic astrocytoma (PA) is a benign tumour of childhood, often located in deep midline structures such as the brainstem and the cerebellum. Gross surgical resection is curative in the majority of patients. We report a case of recurrent PA di...

Comparative metabolic profiling of paediatric ependymoma, medulloblastoma and pilocytic astrocytoma.

Brain tumours are the most common solid tumours in children and a major cause of childhood mortality. The most common paediatric brain tumours include ependymomas, cerebellar astrocytomas and medulloblastomas. These brain tumours are highly heterogeneous regarding their histology, prognosis and therapeutic response. Subtle biochemical changes can be detected in intact tissues by High-Resolution...

Unusual Presentation of Pilocytic Astrocytoma

Pilocytic astrocytoma (PA) is the benign variant of astrocytic tumours. Pilocytic(Greek word Pilos=hair) refers to frequent presence of cells with bipolar hairlike processes. Pilocytic tumours are juvenile astrocytomas commonly presenting during first two decades of life with a lowered occurrence in adults. Cerebellum is the favoured site. Spinal cord is the rare site of presentation. We report...

Supratentorial pilocytic astrocytoma in children.

Brain tumors hold second place in tumoral pediatric pathology and have a complex etiopathogeny. The authors describe the case of a child aged 2 years and 4 months with increased intracranial pressure, symptomatology accompanied by rapid deterioration of general condition. Head CT imaging examination showed intra-nevraxial replacement space process, supratentorial. Histopathological examination ...
