An imperforate Hasner valve causes the distal blockage, but the cause of proximal obstruction is less clearly understood but the Rosenmuller valve has been implicated Dacryocystocele commonly manifest as a tense, blue-gray mass at the medial canthus or in the nasal cavity Features of MRI are compatible with right dacryocystocele (acquired). Dacryocystocele commonly manifest as a tense, blue-gray mass at the medial canthus or in the nasal cavity due to primary or acquired nasolacrimal duct obstruction. 1 article features images from this case 11 public playlist includes this cas .. Axial non-contrast. There is a well-defined thin-walled cystic lesion of the left medial canthus at the nasolacrimal duct, measuring 28 x 20 x 18 mm with fluid homogeneous content (mean density = 18 HU) and no peripheral enhancement on contrast-enhanced images

Congenital dacryocystocele is an uncommon consequence of congenital nasolacrimal duct obstruction: it is believed to occur as a result of a concomitant upper obstruction of the Rosenmuller valve and lower obstruction of the Hasner valve 1-3 Dacryocystocele. A dacryocystocele is a benign, usually congenital cystic mass that forms at the inferomedial canthus due to obstruction of the proximal and distal ends of the nasolacrimal duct. Patients typically present with a triad of imaging findings, including a medial canthal mass, an enlarged nasolacrimal duct, and an intranasal mass
Congenital dacryocystocele is a commonly accepted term and its use should be advocated to enhance uniformity in reporting. Endoscopic evaluation of CDC is useful in the diagnosis and treatment of associated intranasal cysts and enhances the rates of successful outcomes MRI of childhood dacryocystocele. We report an unusual presentation of a dacryocystocele in a 3-day-old child, with clinical and novel MRI findings. The literature contains extensive CT documentation, but descriptions of the MRI appearances of dacryocystoceles are lacking. Although CT is the standard initial imaging modality, MRI can be helpful. dacryocystocele having a maximum diameter of more than 5 mm in a singleton pregnancy were included in this study. For each case, maternal age, gestational age (GA) at first detection from the first date of the last menstrual period, and US features of the lesion, such as maximum diameter, side, and associated abnormalities, were recorded

Neo-nates with bilateral lesions (in 10% of cases) can present with severe respiratory distress, especially during feedings. A similar clinical presentation is seen with bilateral choanal atresia and pyrifor Congenital dacryocystocele (CD) is a rare disorder about which little is known. A nonsystematic review was performed with an addition of four new cases. Thirty-seven studies were reviewed. The mean gestational age at evaluation was 32 ± 1.09 weeks suggesting that CD is a disorder of late second and third trimester Dacryoliths are a rare clinical finding. They appear as focal areas of high attenuation within a soft tissue attenuation in the nasolacrimal sac or nasolacrimal duct as demonstrated above. Occasionally they have a rim of calcification and hence.. We report an unusual presentation of a dacryocystocele in a 3-day-old child, with clinical and novel MRI findings. The literature contains extensive CT documentation, but descriptions of the MRI appearances of dacryocystoceles are lacking. Although CT is the standard initial imaging modality, MRI can be helpful if there are questions as to the content of the lesion or a need for further.
The authors present a case of a newborn with bilateral dacryocystocele in whom repeated probing was unsuccessful. An associated intranasal cyst was diagnosed. Using fiberoptic nasal endoscopy, treatment consisted of probing, irrigation and marsupialization of the cyst. This rarely reported anomaly i Complications include infection, intranasal extension, airway obstruction (if bilateral), and rarely intraorbital extension. Massive orbital extension of a dacryocystocele can mimic other orbital masses, including encephalocele, dermoid cyst, or neoplasms, and may require adjunctive imaging for diagnosis

CONCLUSION: Dacryocystocele after surgery for sinonasal cancer has a characteristic appearance on CT and MR imaging. Familiarity with this complication of sinonasal surgery and its appearance on imaging will enable radiologists to avoid misinterpreting dacryocystocele as a recurrent tumor or another process Congenital dacryocystocele (CD) is a rare condition and presents as a periorbital cyst in prenatal examinations. CD has high rates of spontaneous resolution in and ex-uterus. However, more severe malformations can present as facial cysts, like encephalocele, venous lymphatic malformation, hemangioma, dermoid cyst, teratoma and rhabdomyosarcoma 1 A congenital dacryocystocele is an uncommon variant of congenital nasolacrimal duct obstruction 1 and usually presents as a blue, cystic enlargement of the lacrimal sac just below the medial canthus. 1 It is usually accompanied by epiphora. 1 These findings are seen at birth or develop within the first few weeks of life, and a secondary dacryocystitis frequently develops. 1 It is often. The radiology was consistent with anterior orbital mass lesions, not involving the lacrimal sac. Histopathology after surgical excision was consistent with three of the lesions being dermoid cysts, one was cavernous hemangioma and one was a solitary fibrous tumor. Dacryocystocele is mostly a clinical diagnosis based on history and examination
Dacryocystitis is inflammation of the lacrimal sac which typically occurs secondarily to obstruction within the nasolacrimal duct and the resultant backup and stagnation of tears within the lacrimal sac. Anatomy: Tears are produced by the lacrimal glands; paired almond shaped exocrine glands which sit in the upper lateral portion of each orbit. Case Reports in Radiology, Vol. 2014 Three-dimensional multiplanar ultrasound is a valuable tool in the study of the fetal profile in the second trimester of pregnancy Ultrasound in Obstetrics and Gynecology, Vol. 35, No. Congenital dacryocystocele (CD) is a rare condition that presents as a periorbital cyst on prenatal examination. CD has a high rate of spontaneous resolution pre- and postnatally; however, more severe malformations can present as facial cysts, such as encephalocele, venous lymphatic malformation, hemangioma, dermoid cyst, teratoma and rhabdomyosarcoma 1 Diagnosis: Bilateral congenital dacryocystoceles. Congenital dacryocystocele, which is a rare complication of complete obstruction of the nasolacrimal apparatus during embryonic development, is commonly diagnosed in utero or during the first few weeks of life. 1 Embryologically, the nasolacrimal apparatus arises from a thickening of ectodermal tissue in the naso-optic fissure between the.
Orbital anomalies can be detected prenatally using ultrasound or magnetic resonance imaging. Some of these include congenital cataracts, hypertelorism, hypotelorism, dacryocystocele, microphthalmia, anophthalmia, orbital tumors/masses, and septo-optic dysplasia. We describe characteristic ultrasound findings of these diseases The dacryocystocele represents a dilated lacrimal sac and is often considered as having a congenital etiology. However, dacryocystocele is a rare disease in adults. The clinical feature is characterized by a painless bulge in the medial region of the orbit, below the medial canthal ligament.

Later, MRI with gadolinium injection (Fig. 4) shows that this pre-maxillary right cystic lesion is not consistent with a dacryocystocele since there is no relation between the mass and the lacrimal apparatus. The heterogeneous signal content of the lesion on T1 and T2 weighted images is consistent with post-traumatic haemorrhagic components A dacryocystocele is the result of obstructing the lacrimal drainage system above and below the lacrimal sac. CT is the imaging modality of choice to map the extent of a dacryocystocele and exclude other nasal masses. 12 Classic imaging features are a round cystic mass at the medial canthus with a thin peripheral wall ( Fig. 10 ) Expert radiology opinion was that these findings were consistent with a right-sided dacryocystocele. it would be very unusual for a dacryocystocele to erode through the orbital septum causing a mass posterior to the globe, and therefore an alternative diagnosis of an ethmoid mucocele should be considered
