Aneurysm of the vein of Galen is a rare midline arteriovenous malformation seen in children. It makes up approximately 1% of intracranial vascular malformation but 30% of all paediatric vascular malformation. The presentation depends on the age and amount of blood shunted to the malformation. A neonate or a child may present with cardiac failure, macrocephaly, headache, focal neurological signs or subarachnoid haemorrhage. We report a case of a 2 year old male child and rare images that presented with macrocephaly and diagnosed to have vein of Galen aneurysmal malformation on CT scan and CT angiography.

Case Presentation

A two year old boy was referred from department of paediatrics to department of radio diagnosis and imaging for evaluation of macrocephaly and delayed development of milestones. The child was born with full term spontaneous vaginal delivery at home. No antenatal ultrasound was performed during this gestation. He had no history of seizure disorder. On systemic examination no significant abnormality was noted. No evidence of any focal neurological deficit was noted. Cardiovascular examination was within normal limits. A non-contrast CT scan [Figure 1] showed a well-defined large rounded homogenous area of increased density with peripheral curvilinear calcification at the posterior third ventricle. There were dilatations of both the lateral and third ventricles. The fourth ventricle was normal. There was no periventricular lucency to suggest acute hydrocephalus. There was no intracranial haemorrhage or midline shift. Contrast examination [Figure 2] showed strong uniform enhancement and confirmed the vascular nature of the lesion and its communication. Diagnosis of vein of Galen aneurysmal malformation was made based on above findings.
