PURPOSE To study the incidence of cerebellar arteries originating directly from the internal carotid artery, and to discuss the probable embryological origin and clinical implications of this anatomical anomaly. METHODS We reviewed 5500 angiographic studies done at our institution in the last 4 years, searching for these anomalous vessels as well as for(More)
The authors studied 58 patients, under 12 years of age, admitted to the Emergency Room of the Sao Paulo University Hospital between September 1987 and November 1991 with the diagnosis of traumatic extradural hematoma. Emphasis was given to the etiology of injury, the time interval from head injury to emergency room evaluation, the clinical features and the(More)
This study discusses the results from the IAP and its lateralizing and prognostic value in patients with temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS). Eighteen patients were submitted to the IAP. Fifteen had bitemporal and 3 unitemporal lobe epilepsies. All patients had MTS on MRI and in one there was an unrelated lesion in the(More)
Corpus callosum stimulation produced by chronically implanted electrodes, placed either by craniotomy or stereotactically, failed to control refractory generalized epilepsy in humans and also in experimentally produced penicillin epilepsy in cats. However, the patients that suffered craniotomy, frontal lobe retraction or pneumoencephalograms, without(More)
A 44-year-old female presented with Duret hemorrhage due to transtentorial herniation by extradural hematoma as a complication after craniotomy for treatment of spontaneous middle cranial fossa cerebrospinal fluid leakage through the oval window. Brain computed tomography revealed linear hemorrhage in the midbrain and the rostral pons. She awoke after 2(More)
A series of 35 patients have been submitted to microsurgical callosotomy since February 1978, their age ranging from 6 to 42 years. The surgical procedure consisted either of a frontal parasagittal trephination or a larger frontoparietal rectangular craniotomy to allow the investigation of the surgical areas of the hemispheres with electrocorticography(More)
A 30 year old woman with primary hypothyroidism due to an ectopic (sublingual) thyroid, with a pituitary tumour invasive to the sphenoidal sinus presented with hyperprolactinaemia, amenorrhoea and galactorrhoea not corrected by long-term thyroid replacement. High basal TSH and TRH hyperresponsiveness were suppressed by thyroid therapy. After transsphenoidal(More)
Neurosurgical treatment of neuropsychiatric illness has evolved considerably since its inception in 1935. The most common psychiatric indications for the procedure, including obsessive-compulsive disorder and major depression, are conceptualized as disorders involving the basal ganglia and limbic system. In this article, the various operations and their(More)
Nodular intracranial calcifications (NIC) are frequent findings in CT scans of epileptic patients in countries where granulomatous central nervous disease such as neurocysticercosis is endemic. In 34 consecutive epileptic patients with NIC submitted to EEG, CT and CSF analysis, the correlation between the electroclinical localization of the focus and the(More)
Meningiomas are benign tumors arisising from arachnoid cells and represent the commonest asymptomatic intracranial tumors. We analysed 69 supratentorial meningiomas managed by the Neurosurgical Tumor Group of the Clinics Hospital of Medicine School of São Paulo University (September 1995 to September 1997). Age, sex, edema degree, tumor site, surgical(More)
