A case of dacryocystocele with intranasal extension is described by magnetic resonance imaging (MRI) characteristics, which are correlated with the appearance on computed tomography (CT) scans. Computed tomography and MRI are equally sensitive in detecting dacryocystocele. Magnetic resonance imaging has the advantages of characterizing the cyst contents, allowing multiplanar imaging without the need for manipulation of the patient, and the absence of radiation exposure. Computed tomography has the advantage of detecting bone changes involving the bony nasolacrimal canal. Clinically, these abnormalities usually resolve spontaneously and only rarely require surgical intervention.
