All tubers are not created equal: Cerebellar tubers in a pediatric patient with tuberous sclerosis.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant disease characterized by multiple tumors throughout the body. Supratentorial hamartomas (or tubers), are a very common CNS feature of TSC. Cerebellar tubers are much less common in TSC. We present an interesting case of cerebellar tuber in a 14-year-old patient with TSC, highlighting clinical and diagnostic criteria for TSC and review the unique features of cerebellar tubers, differentiating these lesions from their more common supratentorial counterparts. This case serves as an educational tool to improve awareness of cerebellar tubers in patients with tuberous sclerosis.
