Peritonsillar abscess in children is a very rare disease. Five patients have been treated at our hospital within the last ten years. The youngest case was a 1-year-old boy. Their chief complaints were sore throats, high fever and vomiting. All patients were hospitalized and treated with intravenous administration of antibiotics. Though one patient received paracentesis and aspiration, the other patients received incision and drainage under local anesthesia. Group A streptococcus was isolated from purulent discharge from two patient, Haemophilus influenzae was isolated from another patient, and no pathogenic bacteria was isolated from the others. They needed about seven days of hospitalization on the average. One patient had a subsequent tonsillectomy. The other patients had experienced no recurrent episodes of peritonsillar abscess.
An 11-year-old boy with fever and pain in the left forehead and the left orbit was diagnosed as sinusitis by plain X-ray and CT scan. Antibacterial therapy with ABPC followed by CPR and CLDM did not improve the symptoms. Examination of cerebrospinal fluid revealed pleocytosis. Numbness began to appear in the right extremities, and MRI findings of fluid collection in the anterior and the temporal area led us to diagnose his illness as subdural empyema. He underwent cerebral decompression and irrigation of the empyema cavity. He recovered and was discharged 76days after admission. The importance of prompt diagnosis by CT scanning or MRI is discussed when fever persists in patients with sinusitis.
