Every Posterior Fossa Mass Is Not a Tumor— Rare Case Report of Isolated Intracranial Infantile Myofibromatosis

Infantile myofibromatosis is the most common fibrous disorder of infancy and early childhood. It can present in three forms—solitary lesion, multicentric with visceral involvement and multicentric without visceral involvement. Intracranial involvement is rare and when it occurs, it is generally extension of extracranial lesion into the intracranial compartment. Here we present a rare case of isolated posterior fossa involvement presenting clinically as congenital facial palsy.
