Sinus Pericraniiの2例

SINUS PERICRANII:A REPORT OF TWO CASES

はじめに

　主として，頭蓋骨正中線上に，やわらかい腫瘤をふれ，しかもその内容が静脈血である一連の疾患に関しては1850年Stromeyerが初めてその2症例を報告^1）し，これをSinus Pericranii （頭蓋骨膜洞）と命名しているが，以来欧米ではその報告も比較的多く，100例以上を数えるに至つている。しかるに一方，本邦における報告例は1962年，伴らの1例の報告^2）のほか，学会における2, 3の発表例が散見されるにすぎない。

　最近まで，東北大学脳研脳神経外科で，この2例を経験，手術，治癒せしめたので報告し，その病因論及び治療につき若干の考察を加える。

Sinus pericranii has been infrequently reported in our country.

We have presented two cases of this disease and discussed the cause and the treatment.

Sinus pericranii is characterized by pericranial blood cyst communicating to the intracranial sinus. However, the pathogenesis of this disease has not been well known at the present stage.

In our cases, one case had slight head injury in the past history, but it could not be directly related to the cause of this disease.

All of our cases were treated with surgical pro-cedure with good results. Angiomatous changes could be found at the time of operation, so it could be suggested that the angiomatous change is more preferable than the trauma as the cause of this dis-ease. As for the surgical treatment, the dissection of pericranial varices was thought to be most use-ful. In addition to describe, venography by direct puncture technique of tumor was available for diagnosis in all our two cases.
