An aneurysm of the cavernous segment of the internal carotid artery concomitant with a cerebellar hemangioblastoma (HB) is extremely rare. A 60-year-old woman with von Hippel-Lindau disease presented with a cerebellar solid tumor manifesting as headache for the past 4 months, progressive vomiting, and ataxia. Angiography revealed a highly vascular mass tumor located in the posterior fossa as well as an aneurysm on the cavernous segment of the internal carotid artery. The ipsilateral anterior inferior cerebellar artery and posterior inferior cerebellar artery branches were the main feeding vessels of the HB. The patient underwent a left-lateral suboccipital craniectomy to remove the highly vascular HB. Successful total excision of the tumor was demonstrated on postoperative magnetic resonance images. The unruptured cavernous sinus aneurysm in this case was not on the feeding artery, which was asymptomatic and has not been treated further. The patient was in good condition at 1-year follow-up.
