All of them underwent magnetic resonance imaging and cerebral digital subtraction angiography DSA.

Diffuse cavernous hemangioma of the rectum is an uncommon disease with less than reported cases that affects mainly young adults. The pathogenesis of hemangioma is still not understood. Computed tomography and particularly magnetic resonance imaging, given their high precision to delimit the lesion and its relations to adjacent structures, are imaging studies that are mandatory before surgical treatment.

The authors report on two cases of association of a cavernous angioma with a ganglioglioma and an oligodendroglioma respectively. Although alternative therapies such as sclerotherapy, criotherapy or argon fulguration caveenoso 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.
