Intracranial Arterial Aneurysms in Infancy and Childhood

Eleven cases of intracranial arterial aneurysms in patients under 15 years of age, treated from 1959 to 1976, are presented. The preponderance of aneurysms at the internal carotid artery bifurcation and the peculiarities of the defects in this location are remarkable.

Chronic spinal subdural hematoma

A 55-year-old woman with chronic spinal subdural hematoma, diagnosed by magnetic resonance (MR) is presented. There was no coagulation defect, anticoagulant therapy, or trauma.

Surgical treatment of unilateral coronal synostosis. Technical notes.

SummaryA modification in the surgical technique for unilateral coronal synostosis is proposed.

Forma tumoral da cisticercose cerebral: diagnostico pela tomografia computadorizada

Solitary granulomatous lesions due to cysticercosis in the brain were found by computed tomography in six patients. The CT images were in all cases very similar to those from brain neoplasms. The cerebrospinal fluid complement fixation test for cysticercosis was negative in all of the cases. The definite etiological diagnosis could only be made by craniotomy in this series.Solitary granulomatous lesions due to cysticercosis in the brain were found by computed tomography in six patients.

Encapsulated spinal epidural hematoma in an octogenarian

An 88-year-old man was found at laminectomy to have an encapsulated spinal epidural hematoma. The surgical result was gratifying and reinforced a recent statement that spinal surgical procedures in the very elderly should not be withheld on the basis of age alone. Moreover, the rarity of this pathology in this age group and the clear identification of the lesion on the computed tomography scan of this case are to be noted.

Tratamento cirúrgico da siringomielia pela Técnica de Gardner

O tratamento cirurgico da siringomielia e, em geral, considerado decepcionante. Varios tipos de drenagem da cavidade siringomielica nao tem fornecido resultados satisfatorios. Gardner, em magnifica serie de trabalhos, mostrou que a siringomielia e as varias malformacoes associadas a hidrocefalia tem fisiopatogenia unica. Baseado em sua teoria, Gardner propos, em 1958, o bloqueio da comunicacao entre o IV ventriculo e o canal central da medula, para o tratamento da siringomielia. Esta tecnica nao tem sido realizada com muita frequencia. Empregamos o metodo proposto por Gardner em 4 pacientes, os quais melhoraram apos a intervencao cirurgica.

Tomografia computadorizada em decúbito ventral e lateral no diagnóstico diferencial entre hematoma subdural e atrofia cortical

The differential diagnosis between brain atrophy versus subdural effusion in children has shown some difficulties in a few cases, mainly when the frontal subarachnoid space is very large on computed tomography. We think that a simple procedure, that is, CT scans in the lateral and prone position following the standard examination, may be worth to clarify those cases of doubtful diagnosis.The differencial diagnosis between brain atrophy versus subdural effusion in children has shown some difficulties in a few cases, mainly when the frontal subarachnoid space is very large on computed tomography.

Papiloma calcificado do plexo coróide: registro de um caso

A case of calcified choroid plexus papilloma in a 7 years old child is reported. The radiologic findings are discussed.A case of calcified choroid plexus papilloma in a 7 years old child is reported. The radiologic findings are discussed.

Tomografia computadorizada no seguimento de pacientes com tumores intracranianos

Computed Tomography (CT) has been very useful in the follow-up of patients with brain tumors. Soon after the craniotomy, CT would show any residual tumor if an incomplete excision was done. CT has been essential when one needs to evalute any deterioration in the patients neurological status post operatively. In such instances, CT may detect brain edema, hematoma, hydrocephalus and the presence of air. CT findings are more accurate than those obtained from conventional neuroradiology or from intracranial pressure monitoring, being also more innocuous than those methods. Later in the post operative follow-up, CT allows, besides precocious diagnosis of tumor recurrences, a good evaluation of the results obtained by chemiotherapy or radiotherapy. When hydrocephalus is accompanieing the primary pathology, ventricular size can be rapidly evaluated by CT. Difficulties may arise when one wishes to differentiate CT images of radionecrosis from tumor recurrences at least in the initial stages.

Anterior communicating artery aneurysms

SummaryA consecutive series of 11 patients with anterior communicating artery aneurysms operated on by a modification of the techniques reported by Poppen and French is presented. The results were good.
