A years old man with iron deficiency anemia had been followed up at the Department of Pediatrics since the age of 5-years old.

The authors report on two cases of association of a cavernous angioma with a ganglioglioma and an oligodendroglioma respectively. Planes of cleavage with surrounding neurovascular structures were not regarded as safe, and none was resected, given the anticipated surgical bleeding. Case 1 A year-old girl was admitted in our department for progressive bilateral facial palsy.

After revision of these two cases it was evidenced that the vascular part assumed a cavernous-angioma like component, while the gliomatous caverboso were a pyloid type ganglioglioma in one case and an oligodendroglioma in other cavsrnoso.

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 with polymorphous aspects; cavernoo both cases the vascular component was observed in some regions of the vavernoso mass.

Genetic researchers are still working on determining the cause of the illness and the mechanism behind blood vessel formation. Discussion We report the case of a young patient with iron deficiency anemia of unknown etiology since childhood. The advent of magnetic resonance imaging MRI raised new diagnostic perspectives for this condition as we report in the study.

In all patients, MRI revealed well-delimited right para-sellar lesions, uniformly isointense in T1-weighted images and hyperintense in T2- T2- and FLAIR-weighted images, brightly enhancing after intra-vascular infusion of gadolinium.

In the treatment of a brain cavernous hemangioma, neurosurgery is usually the treatment chosen. Although, Rubinstein 15 accepted the term angioglioma; in a more recent publication 16 he suggested the restriction of cavernso term angiogliomas to denote a mixed tumor composed of an hemangioblastoma and astrocitoma.

It is the leakage of blood, known as a hemorrhage from these vessels that causes a variety of symptoms known to be associated with this disease. Differential diagnosis with para-sellar meningiomas and schwannomas can be difficult.

It has been suggested that growth factors and hormonal influences contribute to antioma abnormal cell proliferation.

The most common clinical presentation is obscure gastrointestinal bleeding, either occult or visible 2,3although obstruction, intussusception, and perforation may occur. Arteriovenous malformation and oligodendroglioma. Based on our experience and on the literature review, we imply that the presence of rare cases of any kind of AVM associated with a glioma abgioma be interpreted as a truly compound tumor, less likely to be an exceptional coincidence.

Radiotherapy may be a useful complement as the primary therapy or as a preoperative adjuvant 2, 4. The most frequent location of gastrointestinal cavernous hemangiomas is the small cavernosl mainly jejunumfollowed by the colon, especially the rectosigmoid.
