Computed tomography and computed tomography dacryocystography imaging characteristics of lacrimal sac cysts in adults: a retrospective study.

ABSTRACT:

Background

Lacrimal sac cysts (LSCs) are rare lacrimal drainage system (LDS) lesions that often present as medial canthal masses or epiphoras in adults. Computed tomography (CT) and computed tomography dacryocystography (CT-DCG) can aid in the diagnosis of LDS; however, the literature is limited to case reports and adult systematic studies, and discriminative imaging pattern and LDS anatomical change analyses are lacking, hindering treatment. Thus, this study sought to analyze the CT/CT-DCG features and LDS anatomy of adults to address these gaps in the literature.

Methods

This single-center retrospective case-control study included patients diagnosed with LSCs at the Eye & ENT Hospital of Fudan University. Patients with a history of prior surgeries, trauma, tumors, or thyro
