Abstract
A 58-year-old woman presented with progressive midforehead swelling and erythema with frontal headache. Investigations revealed erosion of the anterior wall of the frontal sinus with subgaleal abscess formation, establishing a diagnosis of Pott's puffy tumour. Pasteurella multocida was isolated in pure growth from an aspirate of the abscess. P multocida is a rare cause of sinusitis. It is isolated from the respiratory tract of asymptomatic individuals and, more commonly, patients with chronic respiratory conditions. Although a cause of osteomyelitis associated with animal bites or scratches, P multocida has not previously been implicated as a cause of frontal osteomyelitis or Pott's puffy tumour. A review of reported cases of Pott's puffy tumour, including clinical presentation, microbiology, treatment and outcome, is provided.
Highlights
Infection spreads from the sinus through the diploic veins anteriorly to the subgaleal space, resulting in frontal bone osteomyelitis, erosion through the frontal bone and subperiosteal abscess formation
We describe a case of Pott’s puffy tumour (PPT) associated with chronic sinusitis and present a literature review of PPT cases
All patients diagnosed as PPT by the authors as well as cases of frontal osteomyelitis with subgaleal abscess found on computed tomography (CT) scan or at surgery are included

A cause of osteomyelitis associated with animal bites or scratches, P multocida has not previously been implicated as a cause of frontal osteomyelitis or Pott’s puffy tumour.

Ostéomyélite frontale (tumeur de Pott) associée à Pasteurella multocida : Rapport de cas et survol de la littérature. P. multocida est une cause d’ostéomyélite associée aux morsures ou aux égratignures infligées par des animaux, et n’avait jamais auparavant été incriminé dans l’ostéomyélite frontale ou tumeur de Pott. In 1775 he described a second case complicating frontal sinusitis
