Giant cerebellar cavernomas in children are rare and must be differentiated from hemorrhagic cerebellar tumors. The diagnosis and treatment of giant cerebellar cavernomas is challenging, but complete surgical resection can lead to favorable outcomes and complete neurological recovery in most cases. We present a case of eight months old baby who was diagnosed with a giant cavernoma resulting in secondary obstructive hydrocephalus with neuropsychiatric presentations. The patient underwent a paramedian craniotomy surgery with a suboccipital approach and complete surgical resection of the cavernoma was done. Over nine months of observation, the child showed improvement in their ability to walk and fully recovered from a neurological perspective. We also conducted a literature review to identify eleven cases of giant cerebellar cavernomas in children, including our case. The data were analyzed to determine the clinical features, treatment, and outcomes of giant cerebellar cavernomas in children.
