X線が著効を示した視床部細網肉腫の1例

A CASE OF PRIMARY INTRACRANIAL RETICULUM CELL SARCOMA

緒言

　原発性脳肉腫の症例は，Bailey （1929）^1）の報告を最初とし，以来現在まで100例程が報告されており，本邦においても10数例の報告をみるが，多くは急性の経過をとり予後が不良とされている。

　最近当教室において，手術およびX線治療により著効をおさめた脳内原発性細網肉腫の1症例を経験したので若干の考察を加えて報告する。

A case of primary intracranial reticulum cell sarcoma was reported.

The patient was a 39 years-old male who com-plained of headache, nuchal pain and difficulty in walking for a month prior to admission, and these symptomes aggravated gradually.

The patient was in the state of somnolence at the time of admission, and he had left spastic hemiparesis and disorientation. The right carotid angiography revealed a thalamic tumor with tern-poral extension.

The right temporal craniotomy was performed, and reddish yellow mass in the anterior temporal lobe was removed. The tumor extended further medially and posteriorly and appeared to infiltrate in thalamus.

Further operative intervention was not performed, because the removal of anterior temporal lobe in-cluding tumor tissue was thought to achieve satis-factory.

After the operation the patient had been semi-comatous for a week but gradually regainedconsciousness by two weeks. Radiation therapy of cobalt 60 was markedly effective, which was confirmed by the carotid angiography prior to and after the radiation therapy.

The histological examinations revealed reticulum cell sarcoma.

No tumor was found in any other parts of the body.

The patient has been well for 8 months after the operation up to the present and no sign of recurrence is found.
