Cellulitis of the eyelids associated with sinusitis and brain abscess

Erythema in the orbital area can indicate systemic and life-threatening diseases. We experienced an unusual and serious case of orbital cellulitis that was difficult to distinguish from a case with good prognosis. A 21-year-old man developed an erythema around his eyes. He exhibited no symptoms that would suggest lesions in deep tissues, but his condition turned out to be cellulitis retrogradely metastasized from an odontogenic sinusitis traced to a dental treatment problem. Computed tomography revealed complication of a large abscess in the frontal lobe. Cellulitis of the orbital area requires particular clinical discretion.
