Cystic lesions are very common in the body, in particular in the ENT field. However, reports of cysts involving the Eustachian tube are very rare.  We present in this report a case of a 49-years-old man who presented for unilateral chronic otitis media with effusion. A rigid endoscopy was done revealing no nasopharyngeal mass. An MRI showed the presence of a cystic lesion in the cartilaginous portion of the left Eustachian tube measuring 10 × 6 mm.  The decision was made to do a left myringotomy with a PE tube insertion, followed by an endoscopic endonasal marsupialisation of the cyst. The cyst was sent to pathology. The pathologist confirmed the presence of a cyst with absence of signs of malignancy. In this article we will review the literature concerning Eustachian tube benign tumors; in particularly benign cysts, and we will discuss the pathology, symptoms, treatment and outcome.
