Patient presenting with frontal subperiosteal abscess and headache: a case of Pott's puffy tumour.

Chronic sinusitis can be complicated with erosion of anterior or posterior wall of the sinus; causing Pott's puffy tumour in the anterior, or epidural abscess in the posterior communication. A 65-year old man with a painful swelling in his forehead is presented. Pott's puffy tumour was diagnosed. CT, MRI, and DTI studies were obtained. Epidural or dural involvement was not present. In the first operation, anterior wall of the frontal sinus wall was opened. Osteomyelitis debridement was performed and the frontonasal duct was enlarged endoscopically. Antibiotics were commenced and were continued for 6 weeks. In the second operation, nasal septum deviation was fixed. Postoperative course was uneventful. The presented case suggests that treatment of sinus osteomyelitis should comprise immediate surgical drainage and osteomyelitis debridement followed by long-term administration of antibiotics. MRI study with contrast should be obtained to rule out epidural abscess and dural infiltration.
