BACKGROUND AND PURPOSE The purpose of this study was to determine the nature, incidence, and radiologic appearance of intracranial vascular anomalies that occur in association with periorbital lymphatic malformation (LM) and lymphaticovenous malformation (LVM). MATERIALS AND METHODS We retrospectively reviewed clinical records and imaging studies of 33 patients ranging in age from the neonata...

Vein of Galen abnormality is a rare congenital malformation of blood vessels of the brain and while often referred to as "Vein of Galen aneurysm" its is really not an aneurysm but usually an arteriovenous (AV) malformation. The following case report will be of interest to sonographers as it demonstrates early prenatal diagnosis of this intracranial vascular abnormality causing cardiac overload ...

An arteriovenous malformation is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. Vascular malformations of the mediastinum presenting as mediastinal masses are very rare. We report a histologically proven case of a posterior mediastinal arteriovenous malformation in a 42-year-old man that was...

the sturge-weber syndrome or encephalotrigeminal angiomatosis is a rare neurological and congenital disorder with a frequency of 1 in 50,000 births. this syndrome is a nonhereditary developmental condition and is characterized by the presence of congenital capillary malformation and a hamartomatous vascular proliferation involving the face (port-wine stain or facial birthmark), sometimes skull ...

Facial vascular malformations can cause dental emergencies that result in fatal or life-threatening and disfiguring situations. A knowledge of vascular malformation, its clinical presentation and its complications can prevent iatrogenically related accidents and minimize potential spontaneous crisis for the patient in the dental clinic. A vascular malformation (VM) is a morphogenetic abnormalit...

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in o...
