Pott's puffy tumour: A report of 2 cases highlighting tuberculosis as a microbiological cause

Pott's puffy tumour (PPT), characterized by subperiosteal abscess formation secondary to frontal bone osteomyelitis, is a rare clinical entity. This case series highlights tuberculosis as an unexpected cause of PPT. Two cases of PPT, diagnosed histologically and surgically managed within a one-year period, were retrospectively analyzed. Clinical, radiological, operative, and histopathological findings were evaluated. Both cases, aged 12 and 26 years respectively, presented with forehead swelling, headache, and low-grade fever. Imaging revealed subperiosteal abscesses involving the frontal bone. Surgical exploration and drainage confirmed PPT, with unexpected histopathological findings of tuberculosis. Anti-tubercular therapy led to symptom resolution and lesion regression. These cases underscore the need to consider tuberculosis as a differential diagnosis in PPT. Timely diagnosis and appropriate anti-tubercular therapy are critical for successful management and prevention of complications. Awareness of tuberculosis as a possible aetiological factor is particularly important in regions with a high disease burden.
