A 49-year-old woman consulted for swelling of the left periorbital region associated with mucopurulent secretion. The ophthalmological assessment revealed a severe palpebral and periorbital edema, with intense pain that prevented the spontaneous opening of the eyelid. The conjunctiva was edematous and hyperemic and there was evidence of mucopurulent secretion from both lacrimal puncta. The study was continued with computed tomography (CT) of the orbits, which showed an increased thickness and density of preseptal soft tissues, associated with distension of the lacrimal sac, with enhancement of its wall after the use of contrast [Figure 1]a. A dense image was identified in the distal portion of the ipsilateral nasolacrimal duct that obstructed the lumen [Figure 1]b, [Figure 1]c, [Figure 1]d. A left dacryocystitis associated with a nasolacrimal duct mucopeptide concretion was concluded. Antibiotic treatment was indicated and a dacryocystorhinostomy was performed, wihch confirmed the diagnosis.
|Figure 1: Orbit CT with contrast in the axial plane (a) shows an increase in the thickness and density of the preseptal soft tissues (arrowheads) of the left orbit, associated with distention of the lacrimal sac (arrow) and enhancement of its wall with contrast. Orbit CT without contrast in the axial plane with bone window (b) shows the mucopeptide concretion in the naso lacrimal duct (arrow). Orbit CT without contrast in the sagittal plane with bone window (c) shows the mucopeptide concretion in the naso lacrimal duct (arrow). Volume rendering technique CT (d) generated with 2 mm thick data, which generates some artifacts, however it adequately shows the mucopeptide concretion in the nasolacrimal duct (arrow)|

| Discussion|| |
Lacrimal system mucopeptide concretions or dacryolithiasiscan manifest clinically when it obstructs the nasolacrimal duct, inducing epiphora, dacryocystitis, mucoid discharge through the punctum or swelling of the medial canthus, as in our case. Diagnosis methods include the dacryocystography, dacryoscintigraphy, ultrasound, CT and magnetic resonance imaging.,,
CT of the orbits presents several advantages in the non-invasive evaluation of obstructions of the lacrimal system, among them the visualisation of the surrounding bone structures, the structures within the orbit, the nasal and perinasal cavities, in addition to its demonstrated ability to visualize mucopeptide concretions in symptomatic patients. The CT findings characteristic of mucopeptide concretions are the identification of hyperdense foci within a mass of dense soft tissue in relation to an inflamed lacrimal gland, lacrimal sac or nasolagrimal duct. These single or multiple foci can have a dense homogenous structure or present a calcified peripheral edge. CT is one of the best options to evaluate the lacrimal system and its obstructive complications.,
