Atypical pediatric orbital cellulitis with cavernous sinus thrombosis and petrous apicitis: a case report.

Orbital cellulitis is a serious vision and potentially life-threatening condition. In this case report, we present a 3-year-old boy who was admitted with orbital cellulitis, complicated by an intraconal orbital abscess, cavernous sinus thrombosis, petrous apicitis, labyrinthitis, and mastoiditis. There was no paranasal sinusitis, which is the most common cause of orbital cellulitis. His condition initially did not improve with intravenous antibiotics, but gradually improved after drainage of the orbital abscess with anticoagulant followed by corticosteroid therapy. We illustrate the importance of having a broad differential in atypical cases of orbital cellulitis, as well as the value of having a multidisciplinary approach to maximize favorable outcomes in these complex cases.
