ABSTRACT
OBJECTIVE AND IMPORTANCE: Ganglioglioneurocytoma is not yet a well defined clinical and histopathological entity; recent reports outline the histopathological features of this very rare trimorphous tumor, under different names with its basic components of gangliocytoma, neurocytoma and glioma. Four previous reports described this tumor in eleven patients. This is the first case report describing ganglioglioneurocytoma in the posterior fossa. CLINICAL PRESENTATION AND INTERVENTION: A 31-year old male with midline posterior fossa ganglioglioneurocytoma is described, providing the neuroimages and histopathological studies. CONCLUSION: Ganglioglioneurocytoma is a rare mixed neuronal and glial tumor that can also occur in the posterior fossa.

The authors report a case of chiasmal compression resulting from hemorrhage into a pituitary adenoma following minor head trauma. The adenoma was still confined to the pituitary fossa and only in retrospect had caused any endocrine effects prior to the accident. The diagnosis in this case was established by computerized tomography, angiography, subsequent surgery, and pathological examination of the specimen. There was significant but partial recovery of vision following surgery.
