Title : Think Twice: A Case of a Glial Heterotopia Mistaken for a Dacryocystocele in a 2-year old Female from the Philippines
Abstract:
A dacryocystocele is a rare congenital disorder characterized by a unilateral, translucent bluish cystic mass below the medial canthus. Patients typically present with watering of the affected eye. This paper describes a 2 year old female who came in with a mass below the right medial canthus, associated with epiphora of the right eye. The patient underwent a cranial CT scan which revealed a non-enhancing cystic mass at the area of the nasolacrimal duct. A working impression of dacryocystocele was made based on the typical presentation as well as the imaging findings. Excision of the mass was done revealing fleshy gray tissue and lack of a cystic component. Histopathology revealed the mass to be a glial heterotopia. Glial heterotopias are benign congenital masses that typically present on the nasal bridge. They are rarely found in the medial canthal area, and rarely present as epiphora. When encountering a patient with a medial canthal mass and epiphora, one must also consider glial heterotopias as a differential diagnosis.
