A case of meningoencephalitis and subdural abscess originating from the paranasal sinusitis was reported. A 12-year-old boy developed a high fever, severe headache, hemiplegia and unconsciousness following a common cold.
Physical examination and laboratory examination showed bacterial meningitis. CT and MRI demonstrated frontal sinusitis, meningoencephalitis and subdural abscess. He was treated surgically with the transfrontal approach (Killian's method) under general anesthesia. Large doses of broad-spectrum antibiotics were administered intravenously before and after surgery. He was discharged without any complication after a few weeks.
For the management of this disease, close monitoring with MRI revealed important intracranial and sinus findings. We successfully treated meningoencephalitis and subdural abscess without neurosurgical procedures. Clinical features and management in this disease were briefly reviewed.
