Pott's Puffy Tumor: A Potentially Deadly Complication of Sinusitis.

Pott's puffy tumor (PPT) is a rare but potentially deadly complication of bacterial sinusitis that consists of subperiosteal abscess and osteomyelitis of the frontal bone. It is best diagnosed with computerized tomography (CT) with intravenous contrast or magnetic resonance imaging and treated with early broad-spectrum antibiotics and surgical intervention. We describe a case of PPT in a 7-year-old patient and present the CT images.
