“…This histological classification allows arteries and veins, and even capillaries to be present in the AVMs, whereas only capillaries or veins are allowed in either capillary telangiectasias or VAs. 32,33) However, the absence of any types of arteries in the resected specimens was difficult to confirm. Old reports of VAs have been questioned and the described lesions are often reinterpreted as AVMs rather than pure venous malformations.…”

The term``venous angioma'' (VA) usually refers to a developmental venous anomaly (DVA). However, a group of vascular malformations called VAs shows no venous abnormalities on angiography. The clinical and histological features of histologically classified VAs were studied in eight patients who presented with hemorrhage or seizures to reevaluate these venous anomalies. Angiography showed no venous abnormalities in six patients. Histological study included immunostaining for smooth muscle actin and glial fibrillary acidic protein. Surgical specimens of 10 cases of cavernous angiomas, 10 cases of arteriovenous malformations, and two cases of capillary telangiectasias were studied to compare these types of VAs. Angiographically occult VAs were surgically removed safely, whereas removal of DVAs was complicated by brain swelling and hemorrhagic infarction of the brain. Histological examination found angiographically occult VAs contained malformed and compactly arranged vessels with partly degenerated walls, whereas DVAs had dilated thin-walled vessels that were diffusely distributed in the normal white matter. This study of our cases and a review of the reported cases of VAs suggests that two different clinical and pathological entities are commonly categorized as``VA,'' angiographically occult VAs and DVAs. These two entities should be carefully distinguished.

Association between cavernous angioma and cerebral glioma. Report of two cases and literature review of so-called angiogliomas

et al. 2011

SummaryThe association between vascular malformations and cerebral gliomas is unusual. While the association between cavernous angioma with gliomatous lesions is even more rare, it is considered by certain authors to be a particular pathological entity termed angioglioma. The authors report on two cases of association of a cavernous angioma with a ganglioglioma and an oligodendroglioma respectively. Subsequent review of the literature on the so-called angiogliomas was conducted. In the author's opinion, the entity of angiogliomas represents a general spectrum of angiomatous neoplasms that include gliomatous tumors, in the majority low-grade gliomas, associated with a major vascular component.

“…VA represents one of the rare vascular malformations (angiomas) of the central nervous system (CNS) which is often divided into four subgroups, including arteriovenous angiomas, telangiectasis, cavernous angiomas, and VA [2,5,[6][7][8][9]. Some authors have added varices to this classification [3,10].…”
