Cerebral arteriovenous malformations in pediatric and adolescent patients differ in terms of clinical presentation, management, and outcomes than in adults. They are more prone to present with hemorrhage so curative managements as open surgery or stereotactic radiosurgery are more commonly required in this age group. A 16-year-old girl diagnosed with obesity-related hypertension was presented with recurrent headache and vomiting despite adequate treatment. Because of her recurrent and relapsing symptoms, cerebral imaging was performed and unruptured arteriovenous malformation was detected. Sterotactic radiosurgery was performed and she has been symptom-free for about 5 years. In a hypertensive patient, when clinical features worsen despite adequate treatment, and when unusual symptoms occur, further imaging techniques should be performed to detect possible secondary causes or accompanying clinical features.
