Torticollis secondary to posterior fossa tumors.

Torticollis in childhood may be a sign of many disorders. Five cases, with torticollis as the initial sign of a posterior fossa tumor, are presented. The diagnosis and treatment of the tumor was considerably delayed in all patients because posterior fossa tumor was not considered in the initial differential diagnosis. In two patients, operative procedures on the sternocleidomastoid muscle were performed before discovering the underlying causative tumors. Four of the five patients also had other associated symptoms such as headache, nausea, and vomiting. It is stressed that in acquired torticollis, posterior fossa tumor be considered in the differential diagnosis.
