✓ A case of lymphomatoid granulomatosis with multiple intracranial lesions is reported. Important aspects of this vasculitis are discussed, including its propensity for lymphomatous transformation, its similarity to Wegener's granulomatosis, its predilection for certain sites, and its resistance to treatment. A correlation is described between the computerized tomography scan and the autopsy findings.

✓ The optimum length of a ventricular catheter to be placed in a particular patient may be difficult to determine when either intraoperative ultrasound is not available or considerable time has elapsed between the diagnostic computerized tomography scan and the operation. An index for estimating ventricular length based on the head circumference of the individual is described. This method was tested clinically and proved to be successful.

✓ This 68-year-old woman underwent a distal gastrectomy for gastric cancer in August 1994. A presumed meningioma of the falx was found incidentally on a staging examination of the gastric cancer, but the meningioma was not treated with surgery. Instead, after gastrectomy the patient received tegafur as adjuvant chemotherapy until February 1996, when she was readmitted to the hospital because of loss of appetite and emaciation but with no recurrence of the gastric cancer. A computerized tomography scan obtained during this second admission showed no change in the meningioma. To improve her general condition, tegafur was discontinued and she was started on a course of the antiestrogen agent mepitiostane. Administration of mepitiostane for approximately 2 years resulted in a marked regression (73%) of the meningioma. This is the first reported case of a presumed meningioma that regressed as a result of use of the antiestrogen agent mepitiostane.

✓ A 55-year-old man presented with dementia and seizures of recent onset. A computerized tomography scan revealed a ring-like lesion in the left occipital lobe, which on resection was found to be a histoplasmoma. Cerebral histoplasmoma is rare and simulates a metastatic brain tumor. Only eight cases of this entity have been reported.

✓ A case of a recurrent hemangiopericytoma of the falx which responded well to radiotherapy is reported. The patient was a 58-year-old woman who received a total of 6000 rads of local Linac irradiation over 6 weeks. One year after completing radiotherapy, a computerized tomography scan showed marked regression of the tumor.

✓ A technique is described for the intraoperative use of ultrasound sector scanning in intracerebral neoplasms (mainly gliomas) for biopsy and for the localization of minor lesions. Altogether, 13 patients underwent sonographic examination: nine had gliomas, one had a meningioma, and three had metastases. Through a trephine hole or a bone flap over the tumor, the ultrasound transducer easily localized the lesion in all cases but one. The striking concordance between the sonogram and the corresponding computerized tomography scan made it easy to take several biopsies from areas where the tumor tissue was suspected to be representative. The results show a close correlation between the biopsy specimen and the specimen obtained at extirpation. In two cases, ultrasonic scanning served as an aid for the surgeon in localizing the tumor prior to removal.

✓ An 18-month-old boy was diagnosed as having a hypothalamic hamartoma. When he was 1 year old, he developed precocious puberty, and at 18 months old, endocrinological tests revealed abnormally high folliclestimulating hormone, luteinizing hormone, and testosterone levels. The center of the hamartoma was subtotally excised, as confirmed on the postoperative computerized tomography scan. Precocious puberty subsided after the operation.
