左側視床附近を広範に浸潤せる異所性Pinealomaの摘出治験例

A CASE OF ECTOPIC PINEALOMA DIFFUSELY INFILTRATED TO LEFT THALAMIC REGION WITH SUCCESSFUL TOTAL EXTIRPATION

　視床部腫瘍は比較的稀であり，その摘出治験例に至つては極めて少数の報告を見るに過ぎない。最近我々は左側の視床，内包，尾状核，レンズ核を広範に浸し，更に左側側脳室体部を占拠し，側角下壁，第三脳室左側壁を浸潤した大なる異所性pinealomaの摘出に成功したので報告する。

A 10-year-old boy was admitted, complain-ing mental change, diabetes insipidus, puber-tus praecox, sensory and motor disturbances of right side of the face and body. The operation was performed under hypothermic anesthesia. The tumor, histologically pinea-loma, which occupied the left thalamus, nu-culeus caudatus and nuculeus lenticularis, and infilltrated diffusely to the body and lateral horn of the left lateral ventricle and the left wall of the third ventricle, was successfully extirpated. His course was he-rein reported in detail.
