The authors presented a case of a 74-year-old male initially suspected of having a left cavernous sinus mass detected on a computed tomography [CT] scan. A magnetic resonance imaging [MRI] and magnetic resonance angiography [MRA] of the brain were performed for further investigation and the lesion turned out to be a tortuous left cavernous internal carotid artery [ICA]. Cavernous sinus mass is a very rare presentation of tortuous carotid ICA. To the best of the authors knowledge, it has never been referenced in the literature.
