Congenital cerebrovascular anomalies in the pediatric age group are myriad with diverse etiologies. The purpose of this paper is to provide an imaging overview of congenital vascular malformations and vascular tumors, as these conditions are varied and the characteristic vascular abnormality may even suggest the underlying systemic condition in helping to guide further management. For example, the identification of an arterial anomaly such as agenesis/hypoplasia/duplication may warrant further evaluation for an associated syndrome. Read More

Pulmonary arteriovenous malformations (PAVMs) are rare, abnormal low resistance vascular structures that connect a pulmonary artery to a pulmonary vein, thereby bypassing the normal pulmonary capillary bed and resulting in an intrapulmonary right-to-left shunt. The spectrum of PAVMs extends from microscopic lesions causing profound hypoxemia and ground glass appearance on computed tomography (CT) but with normal catheter angiographic findings to classic pulmonary aneurysmal connections that abnormally connect pulmonary veins and arteries. These malformations most commonly are seen in hereditary hemorrhagic telangiectasia (HHT). Read More

Background: Brainstem cavernous malformations represent around 8%-22% of all intracranial cavernous malformations but exhibit a higher annual incidence of hemorrhage (2%-3%) compared with other cavernous angiomas and tend to be more symptomatic given their proximity to critical nuclei and fiber tracts. Recently, endoscopic endonasal techniques have been used for the removal of ventral skull base lesions, with significant improvement in operative morbidity and mortality compared with open approaches. Here we demonstrate the utility and feasibility of the endoscopic transclival approach for ventrally located pontine cavernomas in carefully selected patients. Read More

Endovascular treatment of carotid cavernous fistulas (CCFs) via a transvenous approach is standard, but in rare cases this approach is challenging due to absence or thrombosis of the commonly used venous routes. A 61-year-old woman presented with a symptomatic CCF with all but one of the venous access routes to the CCF thrombosed, leaving an engorged superficial middle cerebral vein (SMCV) as the only venous outflow from the cavernous sinus. Access to the CCF was made possible after careful navigation of the sigmoid sinus, the vein of Labbé and the SMCV, bypassing the need for surgical access to the SMCV or for a direct transorbital puncture.

The radiological signs of intracranial dural arteriovenous fistulas (ICDAVFs) are heterogenous. While it is commonly accepted that hyper intense T2 wedge magnetic resonance imaging of the brainstem and cervical cord mainly concern gliomas, it is so far uncommon and probably unknown that ICDAVFs can imitate similar radiological pattern, especially with gadolinium contrast enhancement and cord enlargement. Thus the angiography is poorly documented in the diagnostic workup. Read More
