Mixed cavernous angioma and glioma (angioglioma) in the hypothalamus--case report.

A 54-year-old female presented with a huge mixed cavernous angioma and astrocytoma in the hypothalamus manifesting as headache, visual field defect, gait disturbance, and convulsion. Radiological studies revealed a huge suprasellar tumor encasing all the major cerebral vessels. Craniotomy disclosed a hemorrhagic tumor poorly demarcated from the surrounding brain which was partially removed. Histological examination of the operative specimen revealed cavernous angioma with low grade glioma in the periphery. The residual tumor responded to radiation therapy remarkably well. An autopsy conducted 3 years later revealed a small hypothalamic astrocytoma with abundant vasculature.
