This report aims to describe a case of sinonasal ACC presenting as a retroorbital mass, raise awareness of this tumour and its rare presentation among both ophthalmologists and otolaryngologists, and provide brief information on its treatment. A 74-year-old female who presented to an external centre with progressive periorbital oedema, congestion, proptosis, and exotropia in her right eye for approximately 4 months was referred with a right retrobulbar mass. During the initial examination, the best-corrected visual acuity was 0.05 in the right eye (OD) and 0.8 in the left eye (OS). There was no significant pathology in the anterior or posterior segments. Eye movements were normal in the OS and moderately restricted in the OD, particularly in upgaze. She reported no otorhinolaryngological complaints, and her examination was normal except for a polyp-like lesion extending from the middle to the inferior meatus.
