Systemic metastasis following hyphema drainage in an unsuspected retinoblastoma

A 6-year-old girl had total hyphema and elevated left intraocular pressure following trivial trauma. B-scan with vector A-scan revealed vitreous opacities consistent with hemorrhage. The drained hyphema did not recur. A left vascular conjunctival mass and massive cervical lymphadenopathy occurred 7 months later. Biopsy revealed extraocular retinoblastoma and lymph node metastasis. Computed tomography showed an intraocular mass with intracranial extension. She died of metastatic disease despite intensive chemotherapy. Retinoblastoma should be suspected in a child with hyphema following trivial trauma.
