Neuroimaging of nevoid basal cell carcinoma syndrome (NBCCS) in children.

Nevoid basal cell carcinoma syndrome (NBCCS, Gorlin syndrome) is an autosomal dominant condition with a wide range of manifestations, including multiple basal cell carcinomas, medulloblastoma, odontogenic keratocysts (OKC) and skeletal abnormalities. Children with NBCCS also have a predisposition for secondary cancers after exposure to ionising radiation. In children undergoing imaging for posterior fossa mass and/or maxillofacial cysts, certain additional findings can raise the possibility of NBCCS. Making the diagnosis can significantly impact patient management, especially for children with medulloblastoma.
