ABSTRACT
Onze pacientes com lesões expansivas do forame jugular associadas ou não a componente extradural foram submetidos a ressecção cirúrgica no Hospital das Clínicas da Universidade Estadual de Campinas (UNICAMP) entre 1998 e 2001. Foi utilizada cirurgia combinada com dissecção do pescoço, mastoidectomia sem transposição do nervo facial e técnica de reconstrução miofascial da base do crânio desenvolvida por um dos autores. Quatro pacientes foram operados via craniectomia retrosigmoidea. Ressecção total foi feita em 9 pacientes, subtotal em um e parcial em outro. Nenhum dos 11 pacientes teve progressão da doença em 2 anos de acompanhamento. Não houve mortalidade. Cinco pacientes tiveram déficits adicionais de nervos cranianos baixos. Nove pacientes mantiveram ou melhoraram suas pontuações de acordo com a escala de Karnofsky. Para adequada abordagem do paciente com tumor de forame jugular, são necessários bom conhecimento anatômico da região, exposição cirúrgica ampla, e técnica de reconstrução eficiente para obter cura com baixas taxas de complicações pós-operatórias.

We studied the clinical, EEG and MRI findings in 19 patients with epilepsy secondary to congenital destructive hemispheric insults. Patients were divided in two groups: 10 with cystic lesions (group 1), and 9 with atrophic lesions (group 2). Seizure and EEG features, as well as developmental sequelae were similar between the two groups, except for the finding that patients of group 2 more commonly presented seizures with more than one semiological type. MRI showed hyperintense T2 signal extending beyond the lesion in almost all patients of both groups, and it was more diffuse in group 2. Associated hippocampal atrophy (HA) was observed in 70 percent of group 1 patients and 77.7 percent of group 2, and it was not correlated with duration of epilepsy or seizure frequency. There was a good concordance between HA and electroclinical localization. The high prevalence of associated HA in both groups suggests a common pathogenesis with the more obvious lesion. Our findings indicate that in some of these patients with extensive destructive lesions, there may be a more circumscribed epileptogenic area, particularly in those with cystic lesions and HA, leading to a potential rationale for effective surgical treatment

Eighteen patients (mean age of 66.5 years) with normal pressure hydrocephalus (NPH) underwent a ventrículo-peritoneal shunt surgery. Prior to operation a cerebrospinal fluid tap-test (CSF-TT) was performed with measurements of gait pattern and psychometric functions (memory, visuo-motor speed and visuo-constructive skills) before and after the removal of 50 ml CSF by lumbar puncture (LP). Fifteen patients improved and 3 were unchanged after surgery. Short duration of disease, gait disturbance preceding mental deterioration, wide temporal horns and small sulci on CT-scan were associated with good outcome after shunting. There was a good correlation between the results of CSF-TT and shunt surgery (X2=4,11, phi=0.48, p<0.05), with gait test showing highest correlation (r=0.99, p=0.01). In conclusion, this version of CSF-TT proved to be an effective test to predict improvement after shunting in patients with NPH.
