- Epidermal nevus syndrome: an unusual cerebellar involvementPublication . Pereira, S; Serra, D; Melo Freitas, P; Santiago, B; Brito, OThe epidermal nevus syndrome is characterized by several developmental anomalies associated with an epidermal nevus. In addition to the skin, other organs commonly affected include the brain, eyes and musculoskeletal system. We report here on a 24-year-old woman with this syndrome who presented with hemifacial hypertrophy, hearing abnormalities, arrhythmia and an unusual infratentorial brain involvement.
- 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.
- Neurorradiologia da síndroma de KallmannPublication . Melo Freitas, P; Carvalho, S; Ribeiro, F; Marnoto, D; Martins, FThe present study refers to the magnetic resonance characteristics observed in a group of three patients with clinical and laboratory evidence of Kallmann's Syndrome. This disease, also named olfactogenital dysplasia, affects the normal gonadal and olfactory development and is clinically characterized by the association of hypogonadotrophic hypogonadism and anosmia/hyposmia. The study protocol, which included the attainment of sagittal and coronal T1-weighted MPRAGE (Multiplanar Rapid Acquisition Gradient Echo) volumetric sequences, showed defective rhinocephalon development in all patients, expressed by the aplasia/hypoplasia of the olfactory bulbs/tracts and/or of the olfactory sulci. The changes observed corroborate the predictable imaging of this genetic disorder and have been mainly visible in the coronal slices obtained. The results shown are more clear evidence that magnetic resonance is an effective method to show the abnormalities in the olfactory region that are invariably found in this syndrome.
