Pseudoaneurysm of the Facial Artery Territory in an Odontogenic Infection Setting
Lopes Oliveira, MJ; Semedo, C; Quintela, MJ; Fragata, I; Gonçalves Coelho, C; Valejo Coelho, PA pseudoaneurysm of the facial artery is a rare event. It results from vessel wall disruption with blood tamponade from the surrounding tissues, and is usually caused by blunt facial trauma, with other etiologies rarely reported. We present two cases of a pseudoaneurysm in the facial artery territory in an odontogenic infection setting, highlighting the importance of computed tomography angiography for diagnosi...

Brás, JM; Guerreiro, RJ; Morgadinho, A; Januário, C; Dias, M; Calado, A; Semedo, C; Oliveira, CR; Hardy, J; Singleton, ABACKGROUND: Mutations in the genes PRKN and LRRK2 are the most frequent known genetic lesions among Parkinson's disease patients. We have previously reported that in the Portuguese population the LRRK2 c.6055G > A; p.G2019S mutation has one of the highest frequencies in Europe. METHODS: Here, we follow up on those results, screening not only LRRK2, but also PRKN, SNCA and PINK1 in a cohort of early-onset and la...
