A case presentation of unilateral cavernous sinus inflammation due to monostotic fibrous dysplasia

Background Craniofacial monostotic fibrous dysplasia is a rare and usually incidental bone pathology. CT comes to the fore in the diagnosis of monostotic fibrous dysplasia and MRI is used to show its relationship to the neighboring structures. Cavernous sinus inflammation may occur due to infectious and inflammatory causes. Inflammation of unknown cause is called Tolosa-Hunt syndrome. Case presentation In this case report, we presented cavernous sinus inflammation accompanying fibrous dysplasia in a 35-year-old female patient, which was seen for the first time in the literature. Conclusions The contrast-enhanced MR images are very important for the diagnosis and follow-up of the patient, in the rare presence of association we have shown in this case.
