“…Ventromedial canthal cysts in close proximity to the inferior lacrimal canaliculus of the left eye were reported in four young Labrador retrievers by Ota et al. 3 and Gerding; 5 however, cysts of the lacrimal canaliculus are rare in both dogs and humans 5,11–13 . In both species, all the reported cases have involved the inferior canaliculus 5,12,13 .…”

A 4-year-old, female, spayed, Labrador retriever was presented with a painless swelling of the left ventromedial eyelid and epiphora of 3 months duration. Bilateral patency of the nasolacrimal system was confirmed by the appearance of fluorescein dye at both nares. Ultrasonography revealed a well-demarcated fluid-filled structure containing echogenic ill-defined material in close proximity to the nasolacrimal system. A transconjunctival surgical approach confirmed the close anatomical proximity of the cyst and the absence of a communication with the inferior canaliculus. The cyst contained multiple intraluminal calculi (dacryoliths). Following surgical excision of the cyst, the epiphora resolved and no recurrence was noted over a 12-month follow-up period. On histopathology, the cystic structure was lined by stratified squamous epithelium, consistent with lacrimal canaliculus epithelium. Presumed progression of a canalicular diverticulum to a cyst with the formation of intraluminal dacryoliths was suspected. Mineral analysis of the dacryoliths revealed a calcium carbonate composition.

“…The diverticulum compresses the canal system causing a trapdoor‐type blockage and allows the endonasal cystic development. A congenital predisposition due to the presence of a diverticulum seems to be possible in our adult dog although it is difficult to confirm with certainty that the lesion was acquired, as in humans, diverticula are often asymptomatic …”

To describe a case of a nasolacrimal canaliculocele with intranasal extension in a dog. A 6-year-old neutered female Jack Russell Terrier was referred to the Centre Hospitalier V et erinaire des Cordeliers for a slowly enlarging mass adjacent to the medial canthus of the right eye of 5 months duration. Ophthalmic exam, ultrasound, fine needle aspiration, dacryocystorhinography and computerized tomography examinations were performed. Rhinoendoscopic treatment with marsupialisation of the endonasal canaliculocele was performed. Physical examination revealed a 3 cm diameter, subcutaneous mass beneath the medial canthus of the right eye, with a defect in the maxillary bone below. Dacryocystorhinography demonstrated blockage at the level of the nasolacrimal duct. Fine needle aspiration confirmed the cavitary nature of the lesion. During rhinoendoscopy, a mass containing watery fluid was found. Following marsupialisation with a large mass wall resection, the lacrimal drainage system irrigated freely in the nasal chamber. The communication of the lumen of the diverticulum with the lumen of the superior but not the inferior canaliculus was clearly demonstrated during endoscopy. Given negative immunohistochemical staining for smooth muscle actin and desmin, nasolacrimal dacryocele appears to be the most likely diagnosis. Histological examination confirmed that no goblet cells were present in the wall of the diverticulum, which is consistent with the canaliculus rather than the lacrimal sac. Complete resolution was observed without recurrence one year after surgery. Despite its rarity, a canaliculocele should be considered in adult dogs with nasolacrimal duct obstruction. Marsupialisation seems to be the appropriate therapy.

“…The masses consisted of two to three lobules extending along the inferior orbital rim and the nasolacrimal canal in both cases and extending to the lacrimal sac fossa in one case. Despite a report of a diverticulum that grew into the inferior orbital rim, most diverticulae arise in the lateral wall of the lacrimal sac as a single pouch [4,5]. The inferior part of the lateral wall is the most vulnerable site for diverticulum since the medial wall is surrounded by the periosteum, and the superior portion of the lacrimal sac is enforced by the orbicularis muscles and the medial canthal tendon.…”

Multilobular Lacrimal Sac Diverticulum Presenting as a Lower Eyelid Mass

Lacrimal sac diverticulum is a rare condition, and its various symptoms complicate differential diagnosis. We present cases of a peculiar type of lacrimal diverticulum. A 5-year-old girl and a 50-year-old woman presented with a protruding mass inferior to the medial canthus. Each lacrimal system was patent to irrigation. The masses compressed and distorted the lacrimal passage and had no apparent connection with the lacrimal sac in dacryocystography or computed tomography. Surgical exploration and complete excision of the masses were completed. Each patient had an inverted Y- and an inverted V-shaped multilobular cystic mass that was pathologically confirmed as a lacrimal sac diverticulum. Lacrimal sac diverticula may rarely take the form of a multilobular cyst and can present as a lower lid mass. We speculate that an abnormality in lacrimal embryogenesis resulted in multiple blind pouches, a peculiar type of lacrimal sac diverticulum.
