title: An unusual cause of headache: Pott's puffy tumour.
abstract: Osteomyelitis of the frontal bone (eponymously known as Pott's puffy tumour) is an extremely rare and potentially life-threatening complication of frontal sinusitis. The entity was first described by Sir Percival Pott, an 18th century neurosurgeon. It is today considered a historical vignette with the introduction of modern antimicrobial agents. Early diagnosis and immediate active treatment are necessary to prevent severe neurologic sequelae. We report on a case of Pott's puffy tumour in a previously healthy young man with a progressively worsening headache and swelling of the frontal bone. Computed tomography and magnetic resonance imaging revealed features characteristic of this condition. Following emergency sinus trephination and 6 weeks of parenteral and enteral antibiotic therapy, the patient achieved a complete recovery.
