Unique Presentation of Pediatric Orbital Varix.

A 2-year-old girl initially presented with an enlarging and fluctuating mass resembling a bruise several months after orbital trauma. CT imaging showed soft tissue contusion and possible hematoma, without cystic characteristics. Surgical excision was conducted and immunohistochemistry staining revealed CD34+ endothelium. The clinical and histopathologic findings were consistent with an orbital varix. To date, there are no published cases of posttraumatic extraconal orbital varix formation in the pediatric population.
