Lacrimal sac dacryolith treated with endoscopic dacryocystorhinostomy: A case report and literature review

Dacryolith is a concretion within the nasolacrimal systemthat may calcify and cause further obstruction of the nasolacrimal pathway. It may cause intermittent epiphora without inflammation or recurrent dacryocystitis and is often diagnosed during dacryocystorhinostomy (DCR). We report the case of a lacrimal sac dacryolith in a 37-year-old man who was referred to our hospital from the eye clinic with complaints of epiphora that were not relieved by medication. He had no history of epiphora. During endoscopic DCR, the presence of dacryolith in the lacrimal sac was detected and completely removed while the pus was drained. The patient was discharged on the second postoperative day with systemic and topical antibiotics. During routine follow-up, the patient was in good condition and had no complaints. We aim to raise awareness among clinicians of this unusual cause of nasolacrimal duct obstruction, which can be successfully managed with endoscopic DCR rather than an open external approach.
