Primary parenchymal cerebral cystic haemangiopericytoma: a 5-year follow up of disease progression.

Haemangiopericytoma (HPC) is a rare tumour of the central nervous system. Previously, HPCs were thought to originate from meninges and ventricular walls. Currently, they are accepted as distinctive mesenchymal neoplasms unrelated to meningiomas. Imaging appearances, clinical progression and haemorrhage into a cystic tumour is documented in an 18-year-old man where the final diagnosis, with histopathological verification, proved to be a cystic HPC. This interesting and illustrative case is discussed with the relevant literature.

Pilocytic astrocytoma of neurohypophysis.

A case of pilocytic astrocytoma of neurohypophysis is presented. The clinical, pathological and MRI features of a rare tumor of the neurohypophysis are described. A 5-year-old girl presented with a 3 month history of lethargy, imbalance and visual disturbances. A MRI revealed a large suprasellar mass. Histopathological examination demonstrated a pilocytic astrocytoma. Its astrocytic nature was confirmed by positive immunostaining for GFAP and the findings of an electron microscopy.
