Introduction: arteriovenous malformations are a rare disease of the central nervous system that occurs as a result of a fistulous connection between arteries and veins without intervention of the preexisting capillary bed. Its incidence is approximately 1.34 per 100,000 inhabitants in developed countries. It primarily affects men and the areas corresponding to the anterior, middle, and posterior cerebral arteries.
Objective: to describe a case of atypically located cerebral arteriovenous malformations in adults.
Case presentation: a case with varied characteristics was presented in which an arteriovenous malformation located in the left parietal lobe of the cerebral cortex was diagnosed by neuroimaging. In this patient, early medical intervention prevented the development of cerebral hemorrhage. She was successfully treated with Ganma Knife radiosurgery and progressed well without recurrence during follow-up.
Conclusions: the diagnosis of this condition is made using neuroimaging techniques in all patients with these symptoms. Ganma Knife radiosurgery may be the ideal therapy in some cases, but not in others; it all depends on how the patient is classified according to the Spetzler and Martin scale. This article provides solid evidence on the role of imaging in the diagnosis and preoperative stratification of these patients.
