[Dilatation of Virchow-Robin spaces in patients with migraine]. / Dilatação dos espaços de Virchow-Robin em pacientes com migrânea.

The Virchow-Robin spaces (VRS) are subpial invaginations making a tubular revestment scabbard that contains a vase between the subarachnoid and subpial spaces. The magnetic resonance imaging (MRI) is the only imaging method able for evaluate this anatomic detail. We studied the possible association between dilated VRS and migraine. Seventy patients with ages ranging from 13 to 54 years (mean, 36.5 years), with clinical diagnosis of migraine were studied and compared with a control group, without past of headache, composed by the same number of patients with ages ranged from 14 to 64 years (mean, 42 years). We observed widening of VRS in 28 cases (40%) of the migraine patients. In the control group this feature was demonstrated in only 5 cases (7.1%). Alert for the importance of detecting and recognizing the VRS, as well as, the differentiation from lacunar infarctions and choroid fissure cysts.

[EPI-FLAIR sequence in the evaluation of mesial temporal sclerosis]. / Uso da sequência FLAIR-EPI na análise da esclerose mesial temporal.

The purpose of this study is to evaluate morphological and signal intensity changes in the hippocampus in patients with medically intractable temporal lobe epilepsy. We studied 8 patients with mesial temporal sclerosis using a 1.5 -T MR and the following sequences Spin Eco- SE, Fast Spin Echo- FSE, Fluid Attenuation Inversion Recovery Echo Planar Imaging--FLAIR-EPI. We noticed a sensitive increase signal intensity on FLAIR- EPI sequences, particularly, in coronal images, than on SE and FSE sequences. The STIR sequence showed a cortical hippocampus atrophy in half of the cases, in whom signal abnormalities were present.

[Trans-sphenoidal meningoencephaloventriculocele in an asymptomatic adult: case report]. / Meningoencefaloventriculocele transesfenoidal assintomática em adulto: relato de um caso.

We report a casual finding of a sphenoethmoidal meningoencephaloventriculocele in an adult patient that the tomography finding was misinterpreted as an expansive neoplastic lesion with malignant features. We alert for the rare site of localization of this malformative pathology.

[High intensity signal in basal ganglia on T1 weighted images: case report in Manson's Schistosomiasis with portal systemic encephalopathy]. / Hiperintensidade de sinal em T1 dos núcleos da base. Relato de caso na encefalopatia portal sistêmica esquistossomótica.

We report a case of mansonic schistosomiasis with portal systemic encephalopathy associated with a high intensity signal in basal ganglia on TI weighted images due to deposition of manganese in tissues related with portal-systemic collateral vessels. A bibliographic review was done focusing the magnetic resonance findings. To the best of our knowledge, these signal changes have not yet been associated with Manson's schistosomiasis.

Reimplantacao de dedos - uma tecnica cirurgica especializada. / Reimplantation of fingers - a special surgical technique

Os autores relatam suas experiencias em reimplantacao de dedos. Eles descrevem e comentam as indicacoes, tecnicas cirurgicas principios de microcirurgia e os cuidados pos-operatorios. A microcirurgia vascular e nervosa e um ramo altamente especializado da cirurgia.Utiliza material ultrafiono e sofisticado com o auxilio do microscopio. A era da reimplantacao comecou com R. Malt (4) em 1962, obtendo exito na reimplantacao de um braco completamente seccionado. Nas amputacoes, medidas urgentes, sao necessarias, nao somente para assegurar sucesso na reimplantacao, bem como para torna-la possivel. O dedo, a mao ou parte amputada devera ser colocada "dentro de um saco plastico e depositado em um recipiente contendo gelo. (1). Fig 5. Na extremidade proximal, arterias e veias nao devem ser pincadas, "e necessario somente um curativo compressivo e elevar o membro, evitando hemorragias". O paciente devera ser encaminhado com urgencia ao servico especializado, para que possa ser iniciada a revascularizacao, no maximo, dentro de 10 horas seguintes ao traumatismo
