A 15-year-old female patient with no known comorbidities presented to pediatric emergency unit with complaints of headache and confusion. Patient's Glasgow coma scale (GCS) was 8(E2M4V2). Patient was immediately intubated. Patient's hemodynamic status was stabilized. Subsequently, a non-contrast cranial computed tomography (CT) scan was performed. Non-contrast cranial CT scan revealed a diffuse intraventricular hemorrhage. External ventricular drainage (EVD) was immediately placed in right frontal horn, and a high-pressure hemorrhagic flow was observed exiting the EVD. Cranial CT angiography revealed the existence of an arteriovenous malformation at head of the right caudate nucleus and in close proximity to the EVD catheter. A diagnostic digital subtraction angiography (DSA) was planned as a subsequent course of action. Diagnostic DSA revealed the presence of an arteriovenous malformation in the surrounding area of the right caudate nucleus head, which was receiving arterial supply from the lateral lenticulostriate artery. Nidus of the malformation was observed to have a diameter of approximately 6 mm, and an aneurysm of 1.2 mm was identified within the nidus. AVM was observed to be draining into the deep circulation via the thalamostriate vein. Level of sedation was gradually reduced, and patient was extubated on the second day of bleeding. Patient's GCS was 15 and no paresis. During the subsequent follow-up period, a notable reduction in the volume of hemorrhagic flow from the EVD was observed. Control computed tomography scans revealed the regression of the ventricular hematoma. EVD of patient was removed on the 7th day of bleeding. Patient who had no wound infections, fever and additional complaints was discharged with the recommendation of neurosurgery outpatient clinic control after 20 days and DSA control after 2 months. On the 2nd month follow-up DSA, it was observed that the previously described arteriovenous malformation adjacent to the right caudate nucleus head regressed.
