Abstract

The patient was a 58 years old male who had complained of left facial paralysis and hoarseness. An autopsy revealed craniopharyngioma which main tumor mass was located at left ventral portin. of the pons.
This tumor has grown up from diaphragm of Sella turcica, not from pituitary gland and pressed and invaded into sinistro-ventral portion of the pons from the left side, invading along dura mata into the surrounding tissues and the both side of tentrium cerebelli and has formed main tumor in it.
This of growth is rare and interesting as craniopharyngioma.
Histologically, the tumor is atypical craniopharyngioma showing the loss of ameloblast layer or incomplete adamantinomous type in most areas and simple squamous epithelioma in some areas.
The relationship between various nervous symptoms and extension of the tumor is discussed. with the literatures.
