We describe a case of a 33-year-old Caucasian @entity1 with right @entity7439 and no sinonasal symptoms. She was referred to the ophthalmology department as having right @entity1736 . On physical examination, she presented @entity735 . The MRI of the brain only showed sinonasal inflammatory signs of the right maxillary sinus. The CT scan revealed opacification of the right maxillary sinus, with retraction of the sinus walls. We confirmed the diagnosis of @entity1817 . The @entity1 underwent functional endoscopic sinus surgery. One year after surgery, despite clinical and aesthetic improvement, slight enophthalmos remained, but there were no other complications. In our case, the diagnosis of @entity7439 as ptosis led to an initial imaging investigation to exclude neurological causes. @entity1817 should be included in the differential diagnosis of @entity7439 . Despite the clinical suspicion, the diagnosis can only be confirmed by imaging studies.

XXXX : an underdiagnosed entity.
