    Notes: Abstract During a 15-year period 37 patients with primary low-grade astrocytoma have been operated upon twice in our institute. CT and histological data at the time of the first and second operations were compared. The majority of primary astrocytomas showed as a low-density area without contrast enhancement; minimal, mainly marginal enhancement was present in six cases. At reoperation 10 tumours were histologically unchanged; the corresponding CT studies displayed a nonenhancing lesion, although insignificant contrast uptake could be seen in three cases. There were 18 tumours which had transformed into anaplastic astrocytoma: CT before repeat surgery showed more or less marked enhancement. In all nine cases which progressed into glioblastoma multiforme strong contrast enhancement was seen on CT at the time of recurrence. Although the grade of contrast uptake varied, the appearance of or increase in enhancement was a sign of some degree of anaplastic change, particularly convincing in cases of dedifferentiated glioblastoma multiforme.

    Notes: Summary A case of malignant melanoma with multiplex brain metastases is described, where both surgical and radiosurgical treatment was applied. Due to CNS manifestations the patient was operated on in two sessions. First the symptomatic large tumor was removed, and the other, small lesion which could not be reached from the same approach was operated later. The primary skin lesion was discovered and removed between the two operations. A CT scan three months after the second operation revealed recurrence at the site of the first operation, and the appearance of two new tumors. The intracranial neoplasms were treated in one session by stereotactic radiosurgery using a linear accelerator. Six months after this treatment a new skin lesion was removed and the patient received DTIC therapy. Successive CT scans after the irradiation showed a steady regression of the radiosurgically treated tumors, and more than one year after the irradiation no tumor could be detected on the CT scans.
