Skull Base Osteomyelitis and Parapharyngeal Abscess as Complications of Otitis Media in a Young Immunocompetent Man

Skull base osteomyelitis (SBO) is a rare and lethal infection of temporal bone, uncommonly caused by purulent otitis media. Although uncommon, a young and immunocompetent person is not exceptional to develop SBO as in our case. We reported a case of SBO in a young, immunocompetent gentleman who presented with right otorrhea associated with fever, trismus, headache, and neck stiffness, which was unresponsive to oral and topical antibiotics. Examination revealed fullness at the right mastoid tip with no evidence of mastoid abscess, trismus, with restrictions of neck movements. Otoscopy of right ear showed mucopus with 10% anterosuperior tympanic membrane perforation without keratin or granulation tissue. Pus for culture and sensitivity grew Klebsiella pneumonia and computed tomography (CT) showed osteomyelitic changes with associated parapharyngeal collection. The patient was started on intravenous antimicrobial therapy and responded well to the treatment.
