Clinical question: Hallucination, new. Signs and symptoms: Altered mental status. Non-enhanced CT of brain: Physiological calcification of bilateral dentate nucleus and the posterior fossa is noted. Images through the posterior fossa otherwise negative for acute findings. There is prominence of the folia of the cerebellum and vermis for age which may represent underlying parenchymal volume loss.Heavy physiological calcification of bilateral basal ganglial is also noted. There is no evidence of acute supratentorial intracranial finding. There is prominence of cortical sulci especially in the left hemisphere for patient's stated age.Correlate with history and further follow-up with an MRI is recommended. Minimal small vessel disease of indeterminate age is suspected.
