Dandy-Walker氏症—成人にみられた一治験例を中心として

A CASE OF THE DANDY-WALKER SYNDROME

緒言

　先天性脳水腫は屡々Luschka及びMagendie氏孔の閉塞により起るが，3孔共閉塞している場合は著明な脳水腫を来たし，成人にみられる事は極めて稀でHolland and Grahamは最近かかる成人の1例を，Walkerの報告に次ぐ第2例目として報告している。

　吾々は成人のかかる1例を経験し，之を手術に依り治癒せしめ得たので茲に報告すると共に，本邦に於ては未だ報告を見ない本症につき些か文献的考察を行つてみた。

An adult case of the Dandy-Walker syndro-me was reported, which was recovered com-pletely by neurosurgical operation.

This disease is considered as the result of the congenital developmental abnormality of the foramina of Luschka and Magendie at the fouth and/or fifth faetal month. Because of that, the adult cases of this disease are rare.

The permeability of the cyst wall would be a large moment which set our case free from any abnormal symptoms nor signs till his 38 years old.

The bibliographical consideration on the pathogenesis, symptomatology and treatment was made on this disease. It is the conclu-sion of this study, that the neurosurgical operation would shows considerably fine re-sult.
