Cerebral Cavernous Malformation in a Patient with Pontine Hemorrhage: A Case Study

The cerebral cavernous malformations are benign vascular hamartomas, with thin and dilated vascular walls and therefore constantly susceptible to hemorrhage. Clinically, they present with recurrent headaches, acute intracranial hemorrhage and focal neurological deficits. They are considered as and the imaging technique of choice for their diagnosis is magnetic resonance tomography. We present the case of a female patient with acute-onset symptomatology, congruent with a lesion in the basal pons. Her medical history included an intracranial hemorrhage due to a cavernoma, which was surgically removed. The magnetic resonance imaging of the brain revealed two new cavernomas, which were not identified in the imaging conducted in the past. In literature, the cases of de novo appearance of cavernomas are considered highly rare, especially in patients with no consistent family history or medical history of radiation therapy. Resultantly, they should be considered as dynamic lesions, regarding their number, size and behavior.
