The diagnosis of brain tumour could not be made in 91 cases at the first investigation in a group of 1155 brain tumours. Slowly growing gliomas causing only epileptic fits and no other symptoms are especially difficult to diagnose. Of 21 personal observations of tumour seizures, in which the diagnosis of the neoplasm was missed at the first investigation in hospital, 9 were oligodendrogliomas, 5 astrocytomas, 3 glioblastomas, 2 spongioblastomas, 1 gangliocytoma and 1 a metastasis. They were all located in the frontal or centroparietal region. In most cases the seizures appeared during the third or fourth decade. The average interval between the first epileptic fit and the tumour diagnosis was 8.2 years in cases of oligodendrogliomas and 2.2 years in astrocytomas. 5 patients had major seizures, 2 had psychomotor attacks and all the others suffered from partial epilepsy. Anticonvulsive therapy was often successfull; either the frequency of the fits diminished or, in 2 cases, the character of the seizures changed. 18 patients had a normal neurostatus at time of the first investigation. Only 3 patients had a slight difference of physiological reflexes, but no other pathological signs. In none of the patients did investigation of the CSF, skull X-rays, brain scanning, pneumencephalography or cerebral angiography first lead to the diagnosis of a brain tumour. The EEG alone showed focal signs corresponding to the location of the tumour in about 50% of the cases.

Clinico-pathologic report of a patient with an oligodendroglioma who ran a 22-year course characterized by focal epileptic seizures of the Jaksonian type. The EEG remained normal for many years. Since the tumor had not been influenced by therapeutic measures, the histologic picture permitted considering some basic problems of origin, growth, and differentiation of oligodendrogliomas.

Both naturally occurring disease processes and experimental models of human disease in the Mongolian gerbil were reviewed. The gerbil was highly susceptible to cerebral infarction following unilateral ligation of one common carotid artery and was useful in studies of the pathogenesis of stroke. Spontaneous epileptiform seizures mimicked those of human idiopathic epilepsy, and both seizure-sensitive and resistant strains have been bred. Perhaps because of its more efficient nephron, the gerbil accumulated four to six times as much renal lead as the rat, and the gerbil has been proposed as an experimental model of lead nephropathy. On standard diets, about 10% of the animals became obese, and some showed decreased glucose tolerance, elevated serum immunoreactive insulin and diabetic changes in the pancreas and other organs. Some breeders exhibited hyperactivity of the adrenal cortex associated with hyperglycemia, hyperlipidemia and degenerative vascular disease. Although dietary supplements of cholesterol were toxic and did not induce atherosclerosis, the gerbil was useful in other studies of cholesterol absorption and metabolism. Spontaneous, insidious periodontal disease became evident after about 6 months on standard diets, and dental caries were induced by cariogenic diets or by pathodontic streptococci. Spontaneous neoplasia occurred in 8.4--24% of gerbils, usually after 2 years of life. Adrenal cortical, ovarian and cutaneous tumors were the most consistently reported neoplasms.

Ninety-five out of 100 male Macaca mulatta of varying ages from a restricted habitat in N. India showed no abnormal seizure susceptibility or EEG response to photic stimulation and no electro-clinical features of epilepsy after pentylenetetrazol, 40 mg/kg sc.c. Autopsy studies on the remaining five monkeys with increased seizure proneness revealed depressed skull fractures with cortical trauma in four and a neoplasm in one. Presumably, these factors were responsible for the lowered seizure susceptibility to photic stimulation and pentylenetetrazol activation.

Clinical (prearteriographic) and arteriographic diagnoses were grouped into six categories each for analysis of central nervous system and systemic complications of 5,000 catheter cerebral arteriograms. Within each category, there was no significant difference in complication rate between clinical and arteriographic diagnoses. The highest complication rates (1.2%-1.9%) were in patients with cerebrovascular occlusive disease, posttraumatic or postoperative conditions, and subarachnoid hemorrhage. Significantly lower complication rates (0.2%-0.5%) were found in patients with tumor, seizure or headache, and patients with normal arteriographic findings.

A 27-year-old woman was admitted to other hospital for acute pleuritis in May 1977. She suddenly had a focal epileptic seizure in the face with loss of consciousness on July 10, 1977. The same episodes of seizure occurred on Aug. 8, on Oct. 26, on Nov. 22, 1977. She was admitted to our hospital on Dec. 12, 1977. Neurological examinations showed no abnormality. Chest X-ray film showed bilateral severe thickening of the pleura. Plain skull films showed normal findings. Enhanced CT scanning showed a homogenous irregular contour of high density area surrounded by low density area in the right frontal region. The lateral ventricle was slightly shifted to the left side. 99mTc brain scan also detected a spherical abnormal uptake in this area. Right carotid angiography showed no abnormal vessels and increased vascularities. On Nov. 22, 1977, a craniotomy was made over the right fronto-temporal bone, and a walnut sized tumor in the frontal subcortex was totally removed successfully. Histologically, the tumor was diagnosed as brain tuberculoma. The antituberculous therapy (AB-PC, INAH, Rifampicin), high doses of gammabenin, and steroid were given. About four months later, she was in good health without neurologic deficits and returned to her work. The literature was reviewed, and the value of CT scan and RI scan in the diagnosis of cerebral tuberculoma was emphasized.

An analysis of the structure and frequency of Jackson's seizures during the illness in 27 patients with brain tumors displayed correlation of these parameters with a histological type of a neoformation and a degree of the involved mediobasal brain structures. In the process of development of the disease the epileptic activity in the EEG was replaced by a slow activity. The displayed peculiarities of the structure and the course of Jackson's seizures taking into account other clinical manifestations can be used in preoperational diagnosis of a histological nature of a tumor.

Eighty-five patients were admitted to the hospital under the preliminary diagnosis of epileptic seizures. None of them had more than five seizures before admission. Sixty-five of these 85 patients had a neurological and electroencephalographic follow-up examination 5 to 7 years later. Another 8 had been readmitted before. From these 8 the diagnosis of cerebral tumor was made in 3 patients. In almost half of the remaining 70 cases the etiology of seizures remained uncertain. The leading known etiologic factors were chronic alcoholism, head injury and perinatal brain damage. Before admission seizures recurred once or twice a year in most patients. After discharge from the hospital 25 patients were without further seizures, 15 of the seizure-free group never received anti-epileptic treatment. The remaining 10 were without medication for a period of time before the follow-up. All seizure-free patients were given the diagnosis of very rare grand mal seizures or seizures of uncertain origin. Only two of the untreated group (total of 17) had seizures after discharge. These findings show that recurrence of seizures was predictable, when patients were discharged. Predictors of recurrance were "treatment" or "no treatment" given initially. Antiepileptic medication should be given in cases of one seizure or more a year, when epileptic origin is certain. Very rare seizures and seizures of uncertain origin may stay without antiepileptic treatment. Sporadic seizures are benign in most cases - comparable to seizures of late onset. Both groups overlap.

Seven patients with cancer complicated by nonmetastatic sagittal sinus thrombosis were encountered in a 7-year period. Five had hematologic malignancies and two had solid tumors. There were two different presentations. In the first, neurologic signs and symptoms (e.g., headaches, seizures, hemiparesis, lethargy) occurred suddenly in five patients shortly after initiation of cancer therapy. Four of these five patients recovered with minimal residua; the fifth died as a direct result of the sinus thrombosis. The second presentation occurred in the two patients with terminal cancer who declined gradually without focal signs; both patients died. Only arteriography can reliably establish the diagnosis of sagittal sinus occlusion. In patients with cancer, sagittal sinus occlusion probably results from a "hypercoagulable state" associated with the systemic neoplasm.

Concerning the clinical signs and symptoms, we noticed skin white macula in 87%, adenoma sebaceum in 53%, mental retardation in 75%, retinal phacoma in 54% and seizure in 92%. Numbers of nodules ranged from zero to 11, and showed no correlation with aging. Half of the cases showed slight ventricular dilatation, one quarter showed moderate dilatation and the remainder were normal. There was no definite correspondence between size of the ventricle and number of nodules. There were relatively many cases with normal mental state in the group with normal ventricles. In adult cases a large ventricle does not always mean poor prognosis in mental state. Almost all of the cases with cortical atrophy had mental retardation. In the group with moderate dilatation infantile spasms were the most frequent type of seizure. On the contrary, grand mal was most frequent in the normal group. As for the position of nodules there was no difference between the normal and dilated groups. Nodules were predominantly seen in the lateral aspect of the body, trigone of the lateral ventricle and adjacent to the foramen of Monro. Asymmetrical lateral ventricles were noticed in 18%. Incidence of laterality increased as dilatation proceeded. It was larger on the left side in 9 out of 11 cases. We have no reasonable explanation of this tendency. There was one case with a tumor which was verified by enhanced CT. There were five cases with brain anomalies.
