Arteriovenous malformation of the head and neck is a rare vascular anomaly but when present is persistent and progressive in nature and can represent a lethal benign disease. An unusual case is presented of an arteriovenous malformation of the base of tongue in a 32-year-old primigravida at 23.2 weeks of gestation with a history of haemoptysis. The patient was admitted to hospital with 10.7 g/d...

A case of arteriovenous malformation of the left cerebellopontine angle causing symptoms of ipsilateral trigeminal neuralgia is reported. Pain relief followed microsurgical removal of the malformation. The authors review the literature on the subject.

BACKGROUND AND PURPOSE Race/ethnicity is associated with overall incidence of intracranial hemorrhage (ICH), but its impact in patients with brain arteriovenous malformation is unknown. We evaluated whether race/ethnicity was a risk factor for ICH in the natural course in a large, multiethnic cohort of patients with brain arteriovenous malformation followed longitudinally. METHODS Data were c...

Seventeen patients with an intracranial arteriovenous malformation were studied with positron emission tomography. Cerebral blood flow, cerebral blood volume, oxygen extraction fraction, and glucose and oxygen metabolism were evaluated in both hemispheres, excluding the area of the malformation itself. Patients were divided into three groups according to the size of their malformation, and resu...

INTRODUCTION Coronary Arteriovenous Malformations (AVM) can lead to various cardiovascular events. The severity of clinical manifestation depends on the degree of the malformation. The significance of major arterial shunt is that they can deprive the myocardium of the necessary amount of blood, leading to myocardial ischemia, and potentially tachycardia, left ventricular dilatation and heart fa...

CONTEXT Upper gastrointestinal bleeding is one of the most common emergencies in gastroenterology. The common causes of the upper gastrointestinal bleeding include peptic ulcer disease, gastric erosive mucosal disease and portal hypertension. Gastrointestinal arteriovenous malformation is a less common cause of gastrointestinal bleeding and these arteriovenous malformation are most commonly loc...

Postpartum uterine bleeding is not uncommon and is caused by a variety of obstetrical and gynecological disorders, such as retained placenta, dysfunctional bleeding, and endometrial polyps. Placental polyps and uterine arteriovenous malformation are disorders often encountered in cases of abnormal uterine bleeding in the late puerperal period. These patients may experience life-threatening blee...

CONTEXT Pancreatic arteriovenous malformations are a rare entity that can be incidentally discovered during MDCT examinations. CASE REPORT We describe a rare case of asymptomatic arteriovenous malformation presenting at MDCT as a hypervascular mass in the pancreatic head. CONCLUSION Pancreatic arteriovenous malformations are a rare entity, often asymptomatic, that can be correctly diagnosed...

The literature regarding arteriovenous malformations of the external ear is sparse. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear that was managed empirically with surgical excision, without recurrence, is presented. The pathogenesis, clinical presentation, radiological work up and management options regarding arteriovenous malformations are rev...
