Summary

Dacryocystitis and nasolacrimal duct obstruction are the main common causes of epiphora. Dacryocystorhinostomy (DCR) is a widely used and effective treatment for dacryocystitis and nasolacrimal duct obstruction. Among these cases, some patients have space-occupying lesions in the lacrimal sac area, such as dacryoliths, mucoceles, granulomas, and even tumors. For patients with lacrimal sac tumors, a more complex treatment plan needs to be adopted, and the severity of the disease and the complexity of treatment should be informed before surgery, since more than 55% of lacrimal sac tumors are malignant.

Therefore, preoperative diagnosis and identification of lacrimal sac space-occupying lesions is important. For lack of imaging examinations, and the symptoms of patients with space-occupying lesions are often similar to those of dacryocystitis and nasolacrimal duct obstruction, which lead to the diagnosis of lacrimal sac space-occupying lesions was not discovered before DCR. CDU has been used for the observation of lacrimal gland tumors. This study has attempted to assess the CDU and CT dacryocystography characteristics of the lacrimal sac space-occupying lesions.
