Pott's puffy tumor: CT and MRI findings

Abstract

Pott's puffy tumor, a subperiosteal abscess of the frontal bone with cranial osteomyelitis, is a rare complication of frontal sinusitis. In this report, we describe the radiological findings of a 24-year-old man, presenting with swelling of the right upper eyelid. Correct and early diagnosis of this infrequent, but potentially life-threatening condition is of utmost importance.
