Silent danger behind the forehead: Pott's puffy tumour presenting without systemic symptoms.

Pott's puffy tumour (PPT) is a rare complication of frontal sinusitis involving subperiosteal abscess and frontal bone osteomyelitis, often leading to serious intracranial sequelae. We report a case of a man in his 50s who presented with progressive, painless forehead swelling despite multiple antibiotic courses. Imaging confirmed bilateral subperiosteal collections and a right-sided epidural empyema. Initial management included broad-spectrum antibiotics, endoscopic sinus surgery and external drainage. Due to persistent collections, a second-stage osteoplastic approach was performed, resulting in complete resolution. Cultures were sterile, possibly due to early antibiotic administration. The patient completed 6 weeks of parenteral antibiotics and remained symptom-free at the 8-month follow-up. This case highlights the importance of early recognition, imaging and surgical management of PPT to prevent complications. An individualised, combined endoscopic and external approach may be essential in advanced presentations.
