A bilateral subfrontal approach was carried out with subtotal resection of the tumor. Cavernous haemangioma in the cavernous sinus: Councillmann in 3 was the first to report the name of “angiogliomas” describing a cerebellar tumor with a huge vascular component. The most important differential diagnosis and the most common preoperative misdiagnosis is para-sellar meningioma. Management of associated primari cerebral neoplasms and vascular malformations.

It is not usually cvaernoso unless the patient is symptomatic. In the eye, it is known as orbital cavernous hemangioma and is found in women more frequently than men, most commonly between the ages of The true incidence of cavernous hemangiomas is difficult to estimate because they are frequently misdiagnosed as other venous malformations. Cavernoma of the cavernous sinus: University Hospital Virgen de la Arrixaca.
Cavernous hemangioma – Wikipedia
Also, the structural support from the smooth muscle is hindered, causing leakage into the surrounding tissue. Patients 2 and 3 were also submitted to computed tomography CT. Histological diagnosis was ganglioglioma with glial component of pyloid type and associated vascular component of angiomatous type angioglioma. Genetic studies show that specific gene mutations or deletions are causes for the disease.
Although alternative therapies such as sclerotherapy, criotherapy or argon fulguration have been used, these procedures are only of limited value in the case of well-defined, small lesions; because of this, most authors have been abandoned these treatment nowadays.
Because of this malformation, blood flow through the cavities, or caverns, is slow. Colonoscopy is without doubt the diagnostic technique of choice, and it allows to establish the localization, morphology, and total extension of the lesion; its characteristic image is a red-purplish nodule with great vascular congestion.

Gamme-knife radiation is the favored mechanism of radiosurgery. Presse Med ; Oligoden-droglial proliferativeabnormality associated with arteriovenous malformation: Aneurysm was excluded in all patients.
In our first case the histological diagnosis was ganglioglioma with glial component of pyloid type and associated vascular component of angiomatous type, while in our second case histological examination showed a glial component of oligodendroglioma cavenoso polymorphous aspects; in both cases the vascular component was observed in some regions of the tumoral mass.
