Congenital Arteriovenous Malformation Located in the Posterior Mediastinum

Unusual location of arteriovenous malformation; posterior mediastinum.

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...

A congenital arteriovenous malformation originating from the aorta locating in the posterior mediastinum.

Vascular malformations located in the posterior mediastinum are extremely rare. Most of them are found coincidentally during routine examinations. Only a small percentage of these posterior mediastinal arteriovenous malformation cases may cause symptoms such as dyspnea due to compression of surrounding tissues. Radiologic imaging can be insufficient in some cases for differential diagnosis. Bec...

Dural arteriovenous malformation in the posterior fossa.

Angiodermatitis associated with congenital arteriovenous malformation on the elbow.

Sir, Angiodermatitis is a common disorder with a clinical and morphological resemblance to Kaposi's sarcoma. In 1965, Mali et al. described the condition ``acro-angidermatitis'' in 18 patients with chronic venous insu¤ciency (1). Other names for this disorder are Stewart-Bluefard syndrome, angiodermatitis, congenital dysplastic angiography, Kaposi-like arteriovenous malformation (AVM) and pseud...

Congenital arteriovenous malformation associated with progressive hydrocephalus in a newborn.

Intracranial arteriovenous malformation is rarely presented in newborns or infants. We describe an unusual case of congenital arteriovenous malformation of the brain with multiple sequestered grape-like venous sacs presented with congenital hydrocephalus. This 4-month-old girl born with a large head, presented with progressive hydrocephalus over a period of 4 months. The brain CT showed multilo...
