INTRODUCTION Auricular Arteriovenous Malformation of the external ear is a rarely encountered disease; in particular, arteriovenous malformation arising from the auricle, with spontaneous bleeding, has seldom been reported. OBJECTIVE In the current study, we report an unusual case of late-onset auricular arteriovenous malformation originating from the posterior auricular artery that was confi...

Pulmonary arteriovenous malformations are rare congenital abnormal connections between the pulmonary arteries and veins. The patients are usually asymptomatic [1]. Although their aetiology is unclear, it is presumed that genetic abnormalities constitute a predisposition [1, 2]. An arteriovenous malformation might cause serious complications if it remains undiagnosed and untreated [3]. We report...

background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...

background hemangioma is the most common tumor of neonatal period and it is almost always appeared by the end of the first week of life and can be found mostly in head and neck area. this study evaluated the synergistic effect of bleomycin, triamcinolone and epinephrine in treatment of hemangioma and arte-riovenous malformations. methods in this multicenter study, a combination of bleomycin, tr...

Arteriovenous malformations of the lower urinary tract are uncommon lesions, usually presenting as scrotal masses. A case of recurrent acute scrotal pain mimicking testicular torsion that was attributed to the presence of an arteriovenous malformation of the spermatic cord is described. To our knowledge this is the first reported case of an arteriovenous malformation of the spermatic cord prese...

An abnormal origin of the ophthalmic artery from the basilar artery, found in conjunction with an orbital arteriovenous malformation, is described. The successful treatment of the arteriovenous malformation by embolization through the ophthalmic artery is also reported.
