Anomalía del desarrollo venoso asociado a telangiectasia capilar un hallazgo infrecuente: reporte de 2 casos

Abstract

Cerebrovascular malformations are rare pathologies in general population (1%), which are diagnosed by neurological symptoms produced by alteration on the dynamics of blood flow, or as incidental findings during CT Scan or Magnetic resonance with contrast agent studies. These lesions have been classified in four types: Anomalies on venous development, capillary telangiectasia, arteriovenous malformations and cavernous angioma. Nevertheless, it has not been possible to conclude if there are different entities or a same disease with different stages, since in some cases there is possible to identify more than one kind of lesion in the same patient, which is known as mixed vascular malformation, making a challenging situation for the medical treatment. The objective of this paper is to expose two cases of patients with mixed vascular malformations, it is the association between a venous development anomaly and capillary telangiectasia, in a supratentorial and in posterior fossa location, as an incidental finding during a magnetic resonance with contrast agent. We share these cases given the infrequency of their report in literature, which surely will allow to complement the knowledge about the natural history and etiology of cerebrovascular malformations, understanding better the pathology and giving a better treatment to the patients.
