These symptoms were resolved by conservative treatment. Histopathology reported a low grade glial proliferation, with an extensive fibrillar matrix, small cells without atypia, extensive calcifications and piloid areas consisting of bipolar fusiform cells, and some Rosenthal fibres.

Neuropathological spectrum of pilocytic astrocytoma: It is a well-circumscribed, slow growing tumour. Spectroscopy of untreated pilocytic astrocytomas: Magnetic resonance of the skull. Pilocytic astrocytoma is more frequent in paediatric patients and in the posterior quiztico.

The patient received treatment with platelet apheresis, corticosteroids and immunoglobulin. The long-term prognosis is good, but it is necessary to perform a follow-up, particularly in adult patients because of a higher risk of recurrence. astrocitomw
