Pott’s puffy tumour and intracranial complications of frontal sinusitis in pregnancy
2013
Introduction: A Pott's puffy tumour is a subperiosteal abscess and osteomyelitis of the frontal bone secondary to frontal sinusitis. Intracranial complications are seen in approximately 40 per cent of cases and are potentially life-threatening; such complications have not previously been reported in pregnancy. Case report: A 21-year-old woman at 35 weeks' gestation presented with a history of frontal headaches and swelling, periorbital oedema, pain and chemosis. Imaging confirmed Pott's puffy tumour with right-sided epidural empyema and periorbital cellulitis. A multidisciplinary team was involved in the patient's management. Intravenous antibiotics were commenced and initial percutaneous drainage through the frontal sinus skin was performed, followed by endoscopic sinus drainage. A caesarean section was performed 3 days later. Complete resolution of the sinus and intracranial collections was noted on imaging performed six weeks later. Conclusion: This case highlights the challenges of managing rare intracranial complications of sinusitis in pregnancy, and the importance of multidisciplinary care.
