被膜骨化を認めた慢性硬膜下血腫の1治験例とその文献的考察

Ossified Chronic Hematorna:One Successful Operated Case

Ⅰ．はじめに

　慢性硬膜下血腫の発生あるいはその消長過程に関してはいまだに定説はないが，ひとたび吸収過程に人った血腫被膜には結合織性の成分が増殖し，器質化していき，一部のものでは被膜の石灰化，さらには骨化へと変化が進むものと考えられている．しかし実際には被膜の石灰化や骨化を認める症例は決して多くはなく，特に組織学的に骨化を認めた症例はきわめて稀である．最近我々は血腫被膜に骨化を認めた興味ある慢性硬膜下血腫の1例を経験したので報告し，若干の考察を加える．

A ease of ossified chronic subdural hematoma was reported.

This patient was 56-year-old man, who suffered from mild head traumas two times in 1966 and 1969, and was a drinker. He suddenly complained of speech disturbince on May 17, 1972, and general convulsion with unconsciousness beginning from the right upper limb on May 21. Slight right hemiapresis and mental disturbance appeared gradually since then, and he was admitted to our hospital on August 15. After some examinations, total removal of the ossified cystic chronic subdural hematoma was performed on August 25.
