- Blue rubber-bleb nevus syndrome: report of a familial case with a dural arteriovenous fistulaPublication . Carvalho, S; Barbosa, V; Santos, N; Machado, EWe report a case of a 45-year-old woman known to have a familial form of blue rubber-bleb nevus syndrome (BRBNS). The patient developed severe occipital headaches and bilateral retroauricular bruits. Cerebral angiography showed a large dural arteriovenous fistula in the torcular region. Central nervous system involvement in BRBNS is not often reported, and most cases of BRBNS are sporadic.

- Fístulas da tenda do cerebelo: diagnóstico e tratamentoPublication . Machado, E; Santos, N; Carvalho, S; Freitas, P; Filho, T; Machado, C; Martins, FAmong the 17 intracranial dural fistulae treated in the Department of Neuroradiology of the University Hospital of Coimbra (17 patients, 28 embolizations) between 19/10/98 and 20/11/2000, 4 cases (23%) were located on the tentorium cerebelli. Three patients were men aged 45, 53 and 56 years old. The remaining patient was an 85-year-old woman. All 4 patients were treated by embolization. One underwent post embolization surgical interruption of the draining vein. The authors analyse clinical presentation, complementary tests, therapy and outcome.
- Hemorragia Subaracnoideia e Angiografia Cerebral por Tomografia ComputorizadaPublication . Santos, N; Machado, E; Carvalho, S; Barbosa, MD; Martins, FWe present a review of 57 cases of nontraumatic subarachnoid hemorrhagesubmitted to CT angiography of the cerebral vessels. The purpose of our study was to estimate the value of CT angiography in the detection of intracranial aneurysms. These findings were compared with those from selective angiography. The results showed that CT angiography is a rapid, low-risk technique with a low level of invasiveness and high specificity and sensitivity in the detection of cerebral aneurysms, allowing the planning of endovascular intervention and surgical approach.
- Malformações do desenvolvimento cortical em doentes com epilepsia: estudo neurorradiológico de 17 casosPublication . Carvalho, S; Brito, O; Machado, E; Santos, N; Melo Freitas, P; Bento, C; Santana, I; Sales, F; Martins, FThis article reviews Malformations of Cortical Development (MCD) diagnosed by Magnetic Resonance Imaging (MRI) in a series of patients with epilepsy. This study spans a five year period. The frequency of these malformations was 7.1%. Most of these were focal or multifocal and the most common ones were polymicrogyria (35.3% of the patients), heterotopia (29.4%), and focal cortical dysplasia (29.4%). The frontal lobes were the most frequently affected regions. The various MCD encountered reflect the wide spectrum of MCD leading to epilepsy.
