Fibrous dysplasia (FD) is an uncommon benign disorder of unknown etiology. It is a localized benign disease of the mesenchyme, which occurs due to the replacement of normal medullary bone by structurally weak fibrous osseous tissue. The disease can involve any bone in the body. Orbital, sphenoid, frontal, ethmoid, temporal and maxillary bones are the most commonly involved structures of the craniofacial region. Involvement of the clivus in FD is extremely unusual, and has rarely been reported previously. Clivus involvement may present headache, neck pain, craniocervical instability or hypoglossal nerve palsy. Diagnosis of FD is based in the radiological imaging findings and mainly the high-resolution Computed Tomography (CT) is the tool of choice. In this article, imaging findings of an incidentally determined rare clival FD case with contralateral mild hearing loss and tinnitus symptoms are presented.
