Rare Case Report: Serratia Liquefaciens and Enterococcus Species as a Cause of Otogenic Brain Abscess Secondary to Active Epithelial Chronic Suppurative Otitis Media (CSOM) in a 12-Year Old Male Patient with Hemiparesis

Developing countries face the problem of Otogenic intracranial complications especially in paediatric population because of poor hygiene, malnutrition and low immunity. Active epithelial type Chronic Suppurative Otitis Media (CSOM) can be the cause of potentially fatal complications. One of these is otogenic brain abscess. Having an estimated annual incidence to be approximately 0.5 per 100,000 children, it is associated with high mortality. We describe a unique case of otogenic brain abscess secondary to Active epithelial CSOM being neglected for two years and finding an unexpected foreign body in the right ear canal in a 12-year-old boy. The consultation was sought when the headache became intense and hemiparesis appeared. Our case is unique regarding both the clinical presentation and the causative organism. The patient underwent craniotomy, with elective capsulotomy, drainage of abscess and placement of a ventriculoperitoneal shunt. This was followed by a modified radical mastoidectomy two weeks later and an uneventful recovery.
