Congenital Dacrocystocele | Case of the Week - Patient Summary 10993 Peer Reviewed and Certified - | |
| Demographics: 15 y.o. girl | |
| History & Chief complaint: | |
| 15 day old female infant with suspected dacrocystocele on physical exam. | |
| Physical exam and Laboratory: | |
| None | |
| Summary of Findings: | |
| There is a well circumscribed cystic mass lesion in the medial canthus which is continuous with the nasolacrimal duct. There is enlargement of the duct distally. There is remodeling of the osseous structures posterior to the mass but there is no invasion or destruction. There is also no communication with intracranial contents. | |
| Differential Diagnosis: | |
| Congenital Dacrocystocele
Dermoid Cyst | |
| Diagnosis: | |
| Congenital Dacrocystocele | |
| Confirmed by: Surgical confirmation | |
| Dacrocystocele is a congenital lesion which results in cystic dilatation of the nasolacrimal duct and cystic medial canthal mass. It is the second most common cause of neonatal nasal obstruction (first is choanal atresia). It occurs secondary to imperforate valves of Hasner (at the distal lacrimal duct). Patients present with inner canthal swelling and epiphoria and eventually periorbital cellulitis and dacrocystitis. The majority spontaneously resolve within first 6 months of life. If they persist, treatments include antibiotics and/or probing to relieve obstruction. The radiologic Diff Dx for medial nasoorbital mass includes encephelocele (often associated w/ hydrocephalus), meningocele, dermoid cyst and nasal glioma. | |
