Congenital infiltrating lipomatosis of the face with enlargement of the ipsilateral cerebellar hemisphere

Abstract

Congenital infiltrating lipomatosis of the face (CILF) is a rare disorder in which overgrowth of fatty tissue with infiltration of underlying structures leads to craniofacial deformities and asymmetry. Imaging plays an important role in the diagnosis, surgical planning and evaluation of underlying structures. To our knowledge, our case is the first to describe CILF associated with isolated enlargement of a cerebellar hemisphere in the absence of an enlarged ipsilateral cerebral hemisphere (hemimegalencephaly).
