Abstract

Background: Cavernous sinus syndrome (CSS) is a rare, but potentially life- and sight-threatening condition. We report a case of multiple cranial neuropathies with CSS.
Case presentation: A 70-year-old woman presented with unilateral complete ptosis, ophthalmoplegia, and diplopia. Examination showed left-sided multiple cranial nerve palsies, with the involvement of cranial nerve III (oculomotor nerve), IV (trochlear nerve), V1 and V2 (ophthalmic and maxillary branches of trigeminal nerve), and VI (abducens nerve). A clinical diagnosis of CSS was made. Neuroimaging revealed a left-sided cavernous sinus mass for further investigation.
Conclusion: In this case report, we highlight the clinical and radiological features of CSS to raise clinical suspicion for similar diagnosis in the future.
