"Pilocytic astrocytoma is the most frequent type of brain tumor diagnosed during childhood. It originates from midline structures and is associated with good prognosis, with an estimated survival rate higher than 95%. We presented the case of a male patient diagnosed at the age of 6 with pilocytic astrocytoma located in the right optic nerve with associated chiasm infiltration. Incomplete resection of the tumoral process was performed, without any additional therapy, as association of chemotherapy or radiotherapy is still controversial among specialists. The patient had an unpredictable severe evolution of the disease, with associated leptomeningeal dissemination and extreme worsening of neurological and endocrinologic status. Six years after diagnosis, despite complex medical efforts the patient died. This article raises awareness of leptomeningeal dissemination risk, a rare evolution in cases of pilocytic astrocytoma. Early diagnosis, complete tumoral resection, tumor location and careful long-term follow up are key factors for long-term survival. "

Optic nerve pilocytic astrocytoma is an uncommon but well-known entity; however, intraorbital ancient pilocytic astrocytoma of the optic nerve is extremely rarely reported. To our knowledge, this is the first detailed description regarding the intraorbital ancient pilocytic astrocytoma, reported in available English literature, to date. We presented an extremely unusual neurofibromatosis type 1 case of a 17-year-old male’s sudden ocular pain secondary to intraorbital pilocytic astrocytoma of the optic nerve with markedly cystic degeneration, fluid production, and hemorrhage, due to ancient and possibly ruptured glioma. Future prospective studies are required to validate the significance of intraorbital ancient pilocytic astrocytoma arising from the optic nerve and the close correlation with ruptured cystic degeneration and ocular pain, after collecting and investigating a larger number of its cases examined.

Astrocytic Hamartoma

A clinical and morphological description of a case of pilocytic astrocytoma (astrocytic hamartoma) of the retina and optic nerve in an 11-year old girl is presented. The clinical and instrumental characteristics of the tumor are determined by ultrasound and MRI tests. Detailed cytological and pathomorphological description of the tumor, which is rarely observed, is given. The tumor poses a threat to the eye and requires that the eyeball be removed.
