Neurotological examination can conclude as arteriovenous malformation of the posterior fossa.

Dural arteriovenous malformation in the posterior fossa.

Pial arteriovenous fistula in the posterior fossa.

Furthermore high vascular lesions may present high perfusion as well as brain cancer. The symmetrical calcifications and the diffuse enhancing nodular lesions are other important findings that suggest a diffuse cerebral condition. Actually the nodular enhancing lesions constitute pre-cystic lesions as same cases show in the literature. Actually the leucodistrophy described in this entity is rat...

Management of posterior fossa arteriovenous malformations

BACKGROUND Posterior fossa arteriovenous malformations (AVMs) are rare vascular lesions, representing 7-15% of all intracranial AVMs. Although less frequent than supratentorial AVMs, they present higher rupture, morbidity, and mortality rates. Microsurgery, radiosurgery, and endovascular neurosurgery are treatment options for obliteration of those lesions. In this paper, we present a critical r...

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...

[Two surgically treated cases with dural arteriovenous malformation in the anterior cranial fossa].

Dural arteriovenous fistulae(dAVF) in the anterior cranial fossa comprise about 6% of all dAVFs, and is usually detected after intracranial hemorrhage. However, non-hemorrhagic symptoms are uncommon. We encountered two patients with hemorrhagic and non-hemorrhagic dAVF in the anterior cranial fossa. Both cases were successfully treated using craniotomy and histopathological examination was perf...
