A Case of Lacrimal Diverticulum with Repeated Swelling of the Medial Canthus as the Main Complaint

Abstract

 Lacrimal sac diverticulum is a relatively rare condition characterized by the formation of a continuous cystic structure originating from the lacrimal sac. While it is often asymptomatic, symptoms, such as epiphora, swelling near the medial canthus, and drainage of pus, may occur. Diagnosis is often challenging because there is no specific test. Treatment generally involves the use of antibiotics. Lacrimal sac diverticulum should be considered a differential diagnosis when evaluating a mass in the medial canthus. Herein, we present a case of lacrimal sac diverticulum with repeated episodes of swelling in the medial canthus as the primary complaint.
