摘要

This report presents a fully thrombosed giant aneurysm of the posterior inferior cerebellar artery (PICA) mimicking an intracranial tumour in a 9-year-old paediatric patient. Surgical clipping and aneurysmectomy were performed. Postoperative imaging studies confirmed the removal of the lesion and the patient was discharged with no neurological deficits. Our case shows that giant thrombosed aneurysms involving the PICA could be potentially misdiagnosed as neoplasms in children and great care must be exercised when managing such cases.
