Brain scanning is of great value in detecting glioblastomas. Since there is little stress upon the patient by this method it is specially suitable for follow-up after surgical treatment and radiation therapy of this tumour, thus giving the best chance of an early detection of a recurrence. On the other hand angiography is essential if further surgery is necessary. Diagnostic problems may arise when using arteriography in cases of avascular recurrences and lack of space-occupying symptoms due to the following factors: Position and small size of the recurrence, growth into the operation cavity, and postoperative
cerebral atrophy
. Avascular mass lesions of other origin may mimic a tumour recurrence in the angiogram. Thus, a combined use of isotope studies and radiological investigations is necessary for an unequivocal detection of
glioblastoma
recurrences.

On the surgery for malignant gliomas, most cases are beyond the stage for desirable removal of tumors, because of the risk of damage to the normal function of surrounding brain tissue. The restriction of the surgical treatment has inevitably required postoperative radiation therapy. With a protocol aiming at removing tumors extensively and delivering high dose radiation to the tumor area, we treated 107 patients with cerebral
glioblastoma
. Wide removal of the tumor combined with intraoperative radiation therapy (IORT) was applied to expected resectable cases at the first surgery or at the second salvage surgery after conventional external radiation therapy. Thirty patients underwent extensive removal with IORT and demonstrated a 2-year survival rate of 60%. Fifty six patients were treated only by postoperative radiation therapy and a two-year survival rate was only 6.8%. The results apparently indicate that areas adjacent to the margin of almost complete removal should be irradiated with a sufficient dose to sterilize the remaining malignant remnants. As metastatic brain tumors without systemic metastasis seldom develop to multiple lesions, surgical removal followed by local radiation therapy would be ideal in order to prevent
brain atrophy
and dementia induced by whole brain irradiation. IORT would be also useful for its strong local effect to tumors and for shortening the hospital stay of patients.

There are very few recorded instances of brain tumors with ipsilateral secondary
brain atrophy
. All 10 cases in the literature are from Japan. We report a case of primary cerebral hemiatrophy with ipsilateral
glioblastoma
. As far as we are aware, no such case has been described in the literature.
