The familial occurrence of brain tumors are exceedingly rare except in cases with phacomatosis. We encountered pituitary adenomas in two sisters of a family, so far presenting no evidence of multiple endocrine adenomatosis (MEA). Case 1, K. O. a 26-year-old woman was admitted to our Hospital on September 10, 1970 with visual acuity and field disturbance, irregular menstruation and acromegaly. Neurological examination: Her visual acuity was Vd 0.6 and Vs 0.3, visual field was bitemporal hemianopsia, and ther was papilledema bilaterally. She had left exophthalmos and left abducens palsy. Roentgenogram of the skull, brain scanning, cerebral angiogram, pneumoencephalogram suggested the presence of a pituitary tumor. On Sep. 17, 1970, through a left frontotemporal craniotomy the tumor was removed subtotally. The pathological diagnosis was pituitary adenoma (chromophobe). Case 2, M. T. a 31-year-old woman, sister of case 1, was admitted to the Hospital on September 19, 1973, with mild headache, left visual field disturbance and amenorrhea. She had a child, and a past history of pulmonary tbc. Neurological examination: Her visual acuity was Vd 1.2 and Vs 0.03, and visual field of the right eye was temporal lower quandrant anopsia. There was optic nerve atrophy in the left eye. Plain X-ray craniogram, brain scanning, cerebral angiogram and pheumoencephalogram suggested the presence of a pituitary tumor. On Sep. 28, 1973, a right frontal craniotomy was performed. The tumor tissue with capsule was removed subtotally. The pathological diagnosis was pituitary adenoma (mixed type). In the literatures about familial brain tumors with histological diagnosis, glioma and glioblastoma are common, meningioma is relatively rare. Pituitary adenoma with no evidence of MEA is exceedingly rare. The two sisters presented in this paper, have no evidence of hyperparathyroidism, pancreas adenoma and peptic ulcer. So, we consider, at present, these cases should not be field in MEA.

Between 1982 and 1988, 174 brains were systematically collected from consecutive, autopsied AIDS patients in a Parisian general hospital without neurology and psychiatry departments. The data obtained under these conditions provide reliable information on the frequency of central nervous system (CNS) involvement in a non-selected population of AIDS patients, most of whom were homosexuals (75.9%). One or several lesions were observed in 148 cases (85%). HIV encephalitis and/or leucoencephalopathy with multinucleated giant cells was found in 33 cases (18.9%). Opportunistic infections were identified in 91 patients (52.3%): toxoplasmosis (65 cases; 37.3%), cytomegalovirus encephalitis (25 cases; 14.3%), cryptococcosis (9 cases; 5.8%), progressive multifocal leukoencephalitis (5 cases; 2.8%), candidosis (1 case) and tuberculosis (1 case). Neoplasias were observed in 23 patients: primary (16 cases; 17.9%) or secondary malignant non Hodgkin's large B-cell lymphoma (3 cas; 1.1%), Kaposi's sarcoma (1 case) and glioma (3 cases; 1.1%). Non-specific lesions (vasculitic, hemorrhagic, metabolic and especially microglial nodules) were common. During the 6 years of study, the rate of CNS involvement was constant. The number of toxoplasmosis cases per year was stable, however, evolutive forms were more prevalent between 1982 and 1986, whereas treated inactive lesions were seen most frequently thereafter. The opportunistic complications were often associated and it should be noted that HIV encephalitis was associated with one of several such infections in 85% of the patients. This high rate of association suggests that these opportunistic infections may play a role in the pathogenesis of HIV encephalitis.

The radiochemical syntheses of methyl 2-[123I]-iodoisonicotinate, 2-[123I]-iodoisonicotinic acid hydrazide and 2-[124I]-iodoisonicotinic acid hydrazide was accomplished. Iodine-123 was incorporated in the methyl ester molecule by an exchange reaction in glacial acetic acid. The average efficiency of iodine exchange reaction was (92.6 +/- 4.5)%. This radiotracer was extracted with ether and the solvent was evaporated. The residue was re-dissolved in anhydrous ethanol and treated with hydrazine under anhydrous conditions to obtain 2-[123I]-iodoisonicotinic acid hydrazide. The overall radiochemical yield was 69%. Biodistribution data of both radio-tracers in male Sprague-Dawley rats were collected. This is the first report of SPECT radiopharmaceuticals which may be useful for differential diagnosis of intracranial masses (tuberculoma vs glioma), and CNS tuberculosis in immunosuppressed subjects.

Information on pre-morbid height and weight from a national screening of tuberculosis between 1963 and 1975 was linked with the registrations in the population-based Norwegian Cancer Registry. For each case with a primary central nervous system (CNS) neoplasm, 10 matched controls were taken from the non-cases. Analyses were done by a Cox regression model for the total group of CNS neoplasms and the various histological groups. In the case of the total group, height emerged as a significant risk factor for both sexes. Within each sex, a similar trend was found for each histological group although statistical significance was retained only for glioblastoma among males and for other types of glioma (astrocytoma, oligodendroglioma, mixed glioma and ependymoma) for females. A significant negative association was revealed between Quetelet's index (weight/height squared) and 'other gliomas' in females. No association with body mass, as expressed by Quetelet's index, was found for patients with meningioma.

The clinical and radiologic findings in 11 patients with brain-stem tuberculoma were reviewed. Clinical manifestations included various combinations of focal signs and symptoms of subacute onset, similar to those produced by other space-occupying lesions of the brain stem. Evidence of systemic tuberculosis was found in six cases (55%). Computed tomography (CT) usually showed an isodense or hyperdense brain-stem mass with abnormal contrast enhancement; associated supratentorial granulomas were found in four cases, and hydrocephalus was found in two cases. Magnetic resonance imaging showed irregular brain-stem lesions with long T1 and short T2 relaxation times. Cerebrospinal fluid findings were also nonspecific, as smears for acid-fast bacilli were most often negative. An incorrect diagnosis of pontine glioma was made in one patient. In contrast, proper integration of data from CT and magnetic resonance imaging findings, cerebrospinal fluid analysis, and x-ray films of the chest permitted an accurate diagnosis in ten cases. Prompt therapy with antituberculous drugs resulted in clinical improvement, documented by CT, in most patients. Brain-stem tuberculoma should be suspected in patients with space-occupying lesions of the brain stem who live in geographic areas where tuberculosis is endemic. Early diagnosis and prompt medical therapy are important in preventing mortality and reducing morbidity.

We studied the occurrence of tumors of the brain and cranial meninges in a cohort of 34,000 California Seventh-Day Adventists who completed a detailed life-style questionnaire in 1976 and who were followed for cancer incidence until the end of 1982. During the period of follow-up, 31 tumors were diagnosed in the cohort (21 gliomas, 10 meningiomas). Increased risk for glioma was associated with rural residence, history of a positive tuberculosis skin test and consumption of pork products; increased meningioma risk was associated with a positive reaction to a tuberculosis skin test, previous stroke, use of tranquillizers and a vegetarian life-style in childhood.

We report a series of 21 patients with basal ganglia and thalamic granulomas or abscesses treated over 7 years. Among them, 15 were tubercular, 5 were pyogenic, and 1 was fungal. Pyogenic abscesses, usually hematogenous, also occurred secondary to osteomyelitis of the skull and chronic otitis media. The fungal abscess developed in a nonimmunocompromised patient with no intercurrent malignancy. Evidence of tuberculosis elsewhere in the body was detected in only 7 patients with tuberculomas. The computed tomographic (CT) image morphology characterizing an abscess or a tuberculoma was present in all except 2 patients with tuberculomas. The fungal abscess resembled a malignant glioma. The only hospital mortality occurred in a deeply unconscious patient with a thalamic pyogenic abscess. A 12-month or longer follow-up in 16 patients showed that 3 continued to be handicapped neurologically, and 2 died 13 and 16 months later, respectively. We conclude that inflammatory lesions at these sites are not uncommon and that CT scans are diagnostic in the great majority. Doubtful diagnosis merits stereotactic aspiration or biopsy of the lesion. Satisfactory results follow adequate medical therapy.

A case of a pontine tuberculoma in a 12-year-old male from Somalia is presented. Cranial magnetic resonance imaging, performed in Abu Dhabi 1 month before admission in Germany revealed a tumorous lesion in the pons with surrounding edema; a presumptive diagnosis of a pontine glioma was made. Chest radiograph disclosed a pulmonary infiltrate with cavitation, as well as hilar and left mediastinal lymphadenopathy, suggestive of active tuberculosis. Tuberculostatic therapy led to an improvement of the patient's clinical status and a significant reduction in the size of the pontine tuberculoma. Intracranial tuberculomas rarely are seen in industrialized countries. They should, however, be considered as an important part of the differential diagnosis of intracranial space-occupying lesions. In most cases, as in this patient, conservative therapy provides good or excellent results.

The radiological abnormalities reported in CNS tuberculosis and their pathological correlates are discussed. Focal tuberculous involvement of the CNS without formation of tuberculoma is rare. The MR features in this case were also distinctly unusual for CNS tuberculosis. Therefore, histological confirmation of all lesions thought to be a low grade glioma is mandatory.

Central nervous system (CNS) tuberculosis (TB), the most dangerous form of TB, remains a public health problem, particularly in developing countries. In the differential diagnosis of intracranial tuberculomas (ICTs), images on radiological findings should be differentiated from other causes of space-occupying lesions. These lesions include malignant diseases such as glioma or lymphoma, pyogenic abscess, toxoplasmosis, neurocysticercosis (NC), sarcoidosis, hydatidosis and late syphilitic involvement of CNS. We present a case with multiple ICTs mimicking NC with similar clinical and imaging manifestations in a young immunocompetent patient. The diagnosis was based on brain magnetic resonance imaging findings. The definitive diagnosis was confirmed mycobacteriologically in cerebrospinal fluid and sputum specimens. Adequate response to anti-TB chemotherapy was achieved while multiple ICTs in the brain disappeared slowly. In the absence of appropriate therapy, these pathologies might be fatal; the possibilities of differential diagnosis would be of great clinical importance, particularly because of the different treatment protocols required for the NC and ICTs.
