title: Recurrent Pott's puffy tumor - atypical presentation of a rare disorder.
abstract: We report the case of a 14-year-old girl who presented with an 8-week history of unilateral pansinusitis. In the course of the disease a right-side frontal swelling was observed, which disappeared following antibiotic treatment. Four weeks later, however, the swelling reappeared and was now diagnosed as recurrent Pott's puffy tumor. Interestingly, C-reactive protein levels were in the normal range throughout. Following functional endoscopic frontal sinusotomy, antibiotic treatment with ceftriaxone was administered over 3 weeks and led to complete remission of the lesion. Pott's puffy tumor is a subperiostal abscess of the frontal bone, usually presenting as localized swelling of the soft tissue in the overlying region of the forehead, and is associated with localized osteomyelitis and occasionally with intracranial epidural abscess. The entity has been known since 1768, although recurrent cases with normal inflammation parameters have not been published previously.
