  • Title: Retinoblastoma with autoinfarction presenting as orbital cellulitis.
    Author: Sachdeva R, Schoenfield L, Marcotty A, Singh AD.
    Journal: J AAPOS; 2011 Jun; 15(3):302-4. PubMed ID: 21680213.
    Abstract:
    We describe a case of unilateral retinoblastoma in a 13-month-old boy who presented with signs of orbital cellulitis. Heterochromia, hyphema, and vitreous hemorrhage were observed. Initial computed tomography (CT) imaging failed to reveal the calcified intraocular mass that was later identified on ultrasonography. Histopathology of the enucleated eye revealed diffuse inflammation and tumor necrosis but with absence of malignant retinoblastoma cells. Genetic testing was equivocal. The patient is presumed to have had retinoblastoma that underwent autoinfarction, leading to secondary inflammation. This case highlights the importance of complete ocular evaluation and proper imaging modalities in children presenting with orbital cellulitis.
