Pott's Puffy Tumor: A Rare Complication of Frontal Sinusitis.

Pott's puffy tumor (PPT) is a rare complication of frontal sinusitis, characterized by subperiosteal abscess formation and frontal bone osteomyelitis, with potential for severe intracranial spread. An 18-year-old male presented with forehead swelling and periorbital edema following recent sinusitis. Imaging revealed bilateral frontal epidural abscesses, osteomyelitis, and pachymeningitis. Surgical intervention included bicoronal craniotomy, frontal sinus cranialization, and abscess debridement. The presence of bilateral epidural abscesses and pachymeningitis represented an unusually severe presentation of PPT. In contrast to typical cases, systemic signs were absent, resulting in delayed diagnosis. Imaging findings and surgical management aligned with current literature and support these approaches in complex cases. Clinicians should suspect PPT in adolescents presenting with forehead swelling in the setting of sinusitis. Early imaging, prompt surgical management, and prolonged antibiotic therapy are essential to prevent life-threatening complications.
