Epidural-cutaneous fistula in association with the Pott puffy tumor in an adolescent. Case report.

The Pott puffy tumor is a subperiosteal abscess associated with underlying osteomyelitis, most often of the frontal bone in conjunction with frontal sinusitis. Intracranial sequelae can include epidural abscess, subdural empyema, intraparenchymal abscess, meningitis, and dural venous thrombophlebitis, all with resultant neurological deterioration. Although once common, this entity has become rare since the introduction of antibiotic agents. The authors present an unusual case of a 14-year-old girl suffering from the Pott puffy tumor whose condition was further complicated by a draining epidural-cutaneous fistula and an epidural abscess.
