PURPOSE To report clinical and MR features that suggest telangiectatic vascular malformations of the pons: METHODS The MR scans and clinical data of 12 patients demonstrating an enhancing pontine lesion with minimal or no signal abnormality on T2-weighted images were reviewed. None of the patients underwent angiography or biopsy. Follow-up scans, available for all patients between 3 weeks and...

Osler–Weber–Rendu syndrome, also known as Hereditary Hemorrhagic Telangiectasia (HHT), is an autosomal dominant disorder. Telangiectasias and Arterio-Venous Malformations (AVMs) are vascular lesions present in HHT, most commonly causing epistaxis and gastrointestinal bleeding. While epistaxis presents as early as childhood, the gastrointestinal manifestations of HHT develop with increasing age.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease. Conjunctival telangiectasias and retinal vascular malformations are known ocular manifestations. We report here the first case of open angle glaucoma in a patient with HHT caused by a nonsense mutation, C471X in the ACVRL1 gene.

Unilateral nevoid telangiectasia syndrome (UNTS) is a rare disease characterized by superficial telangiectasias in a dermatomal distribution. It is generally unilateral and frequently distributed in the C3-C4 or trigeminal nerve dermatomes (1). There are various opinions on the pathogenesis, which can be congenital or acquired. Here, we intended to make a new contribution to the pathogenesis of...

BACKGROUND AND PURPOSE Enhancing lesions on brain MR imaging can present a diagnostic quandary as both benign lesions such as brain capillary telangiectasia and pathologic lesions such as demyelination may appear similar. Stagnation of blood in low-flow venous channels of brain capillary telangiectasias results in susceptibility effect secondary to the increased local deoxyhemoglobin. Both T2* ...

A síndrome de Rendu-Osler-Weber é uma doença sistêmica com acometimento múltiplos órgãos. É caracterizada por telangiectasias e malformações arteriovenosas podendo resultar em sangramentos crônicos, anemia, insuficiência cardíaca, hepática, alterações sistema nervoso até mesmo óbito. O artigo objetiva relatar um caso paciente 62 anos diagnóstico da patologia múltiplas internações, evoluindo par...
