Sinusitis and frontal oedema. What to suspect?

Pott’s puffy tumour is a rare complication of sinusitis, a very common disease. It is a fluctuating swelling of the forehead resulting from a subperiosteal abscess secondary to osteomyelitis of the frontal bone. The progressive spread of the infection may cause serious complications and lead to a surgical emergency, which has an impact on patient outcomes and morbidity. Its incidence has progressively decreased with the introduction of vaccines and antibiotics, although its actual magnitude is unknown due to underdiagnosis. However, nearly 50 cases have been detected in the last 40 years, so clinicians should be aware of this disease and continue to consider it.
