The posterior fossa arteriovenous malformation (AVM) is uncommon and different from other intracranial AVM in its natural history, diagnosis, treatment, prognosis, and other features. Authors present a review of the actual procedures of diagnosis and treatment in the field of infratentorial cerebral arterio-venous malformations, based on the actual literature data. Pre-therapeutic consideration...

This report is of a rare case of mixed oligo-astrocytoma and arteriovenous malformation (AVM) associated with an aneurysm in a 50-year-old man, who presented with a progressive history of headache and vomiting due to acute intracranial hemorrhage. Initial images were suggestive of a right frontal AVM and an aneurysm on the left anterior cerebral artery (ACA) for which a right frontotemporal cra...

BACKGROUND The co-occurrence of intracranial arteriovenous malformations (AVMs) and cerebral neoplasms is exceedingly rare but may harbor implications pertaining to the molecular medicine of brain cancer pathogenesis. CASE DESCRIPTION Here, we present a case of de novo AVM within an isocitrate dehydrogenase 1 mutated anaplastic oligodendroglioma (WHO Grade III) and review the potential contri...

Jejunal polypoid arteriovenous malformations (AVMs) and jejunojejunal intussusceptions are both rare. Here, we present the case of a 61-year-old woman who suffered intermittent episodes of abdominal pain over the course of 13 years. A computed tomography scan of her abdomen and pelvis revealed a distal jejunojejunal intussusception. A suspected low density mass was observed at the tip of the in...

High-flow arteriovenous malformations (AVMS) of the mandible, though rare, may cause death from intractable bleeding, usually following a dental extraction [1-3]. Treatment is difficult, as evidenced by the large range of therapies that have been proposed. These include repetitive embolization, embolization andjor surgical resection, and curettage [1 , 4-6). Nevertheless, some authors have desc...

Arteriovenous malformations (AVMs) are congenital lesions that cause brain haemorrhage in children and young adults. Current treatment modalities include surgery, radiosurgery and embolization. These treatments are generally effective only for small AVMs. Over one third of AVMs cannot be treated safely and effectively with existing options. Several animal models have been developed with the aim...

Arteriovenous malformations (AVMs) associated with aneurysm have rarely been reported in the literature. The present study reports the case of a 21-year-old pregnant female patient who presented with a subarachnoid hemorrhage and an intracranial hematoma located in the anterior end of the corpus callosum. Furthermore, an anterior cerebral aneurysm and an AVM were identified by digital subtracti...

Intratesticular arteriovenous malformations (AVMs) are extremely rare benign incidental lesions of the testis. Ultrasonography (US) generally reveals a hypoechoic solid mass within the testicular parenchyma. We describe a patient with intratesticular AVM which was found incidentally during workup for infertility. The gray-scale and Doppler US appearance of an intratesticular AVM and the differe...

Arteriovenous malformations (AVM) are high-flow lesions having a direct connection between an artery and vein, with bypass of the capillary bed.1 Those affecting the upper limb and causing cardiac decompensation are rare. Treatment of such lesions remains a surgical challenge. Despite multiple procedures, total eradication is often not achieved. For some patients, limb amputation becomes necess...

Increasing evidence supports the use of embolisation to treat pulmonary arteriovenous malformations (AVMs). Most pulmonary AVM patients have hereditary haemorrhagic telangiectasia (HHT), a condition that may be associated with pulmonary hypertension. The current authors tested whether pulmonary AVM embolisation increases pulmonary artery pressure (P(pa)) in patients without baseline severe pulm...
