Report of two cases of Moyamoya disease at the LosComuneros University Hospital (Santander)

Moyamoya disease (MMD) is a vascular disease characterized by a progressive narrowing of the terminal portion of both internal carotid until its occlusion, associated with an abnormal vascular network of collateral vessels in the brain stem which generate a characteristic angiographic pattern that resembles a puff of smoke or moyamoya in Japanese, hence its name, given in 1969 by Suzuki y Takaku, (2, 3). Although its etiology is unknown, there have been some cases where it is related to other diseases, which may suggest genetic factors in its pathogenesis. Moyamoya disease is rare in the world, in fact, it is reported mainly in Japan with a prevalence and incidence of 6.03 and 0.54 per 100 000 inhabitants respectively. Because of this, two cases of moyamoya presented in the Hospital Universitario los Comuneros de Bucaramanga between December of 2014 and January of 2014 were documented. The cases were detected in two male patients of 27 and 46 years old, who presented clinical evolution of two weeks of strong headache, and after neuroimaging studies like Computerized Axial Tomography (CAT) scan and Angiotac for case number 1 and brain tomography for case number 2, they were diagnosed with Pan-angiography.
