Computed tomography and magnetic resonance imaging findings of acquired dacryocystoceles.

In this study, radiological findings of acquired dacryocystocele are presented. A total of 13 dacryocystoceles including bilateral in two of the patients, in four patients on the left and in five patients on the right, were determined. Six of the patients had dacryocystocele infection. Average density of the non-infected dacryocystoceles was 11.8±7.8 Haunsfield units (HU), while the median density value of infected ones was 35.0 HU. There was expansion on unilateral nasolacrimal duct in four patients. Acquired dacryocystoceles are rare masses in medial canthal area, and their radiological imaging findings may vary based on etiological factors and presence of infections.
