Association between draining vein diameters and intracranial arteriovenous malformation hemorrhage: a multicentric retrospective study.

Purpose: Intracranial arteriovenous malformations (AVMs) cause hemorrhage, and the role of draining vein diameters in rupture risk is controversial. The aims of the present study were to investigate the variables related with intracranial AVM rupture and to examine the association of draining vein diameters and AVM hemorrhage.

Methods: Two hundred three patients were included in this study, of which 117 (57%) had unruptured AVMs, and 86 (43%) had ruptured AVMs.

Curative endovascular treatment for low-grade Spetzler-Martin brain arteriovenous malformations: a single-center prospective study.

Background: The treatment of low grade Spetzler-Martin (SM) brain arteriovenous malformations (AVMs) has been debated in unruptured cases. Nevertheless, in clinical practice there are cases where treatment is preferred; in these cases a very low complication rate is mandatory. In ruptured cases, early and complete obliteration of the nidus is the preferred strategy.

Giant mucopyocele associated with intracranial hypertension: Case report and literature review.

Background: Mucoceles are epithelial lined sacs that contain mucous. Eventually, they can be infected and so called mucopyoceles, which are usually slow growing lesions with common bone destruction located in the facial sinus. Mucoceles show multivariate etiology and occur between the fourth and seventh decade of life.
