Pott's puffy tumour of the frontal and Parietal bones with subgaleal abscess as a complication of acute sinusitis - a case report

Acute sinusitis is a frequent medical condition that can affect any age group and may lead infrequently to very serious life-threatening complications. These complications include the spread of infection to frontal and other cranial bones, meninges, and other intracranial structures that require urgent medical actions to prevent mortality and morbidity. We report the case of acute frontal sinusitis in a 14 years old male who presented with fever, severe headache, and fluctuant swelling of the nasal root, and right supraorbital and frontoparietal regions. Imaging studies demonstrated signs of left-sided sinusitis, osteomyelitis of the frontal bones, and right parietal bone. Urgent surgery was performed with drainage of the abscesses and samples were sent for culture and sensitivity. Bilateral antral washout and trephination of the left frontal sinus was performed and pus was evacuated. Growth of Staphylococcus aureus and Peptostreptococcus micros was reported and according to the sensitivity report, the patient was kept on intravenous meropenem, 1500 mg per day and vancomycin 1500 mg per day was added on the 7th postoperative day. The patient was discharged from the hospital in good health on the 25th postoperative day and kept on oral vancomycin for one month.
