Unrecognized Petrous Apicitis as a Cause of Long- Lasting Headache in a 5-Year-Old Child: Case Report

Petrous apicitis (PA) is an extremely rare complication of otitis media (OM), one of the most common infections in children. We describe a case of PA in a 5-year-old girl who remained misdiagnosed for a time because of its presentation mainly as a headache and the late onset of the characteristic symptoms. Our patient received an initial diagnosis of non-suppurative OM, but after a course of antibiotic treatment, her headache persisted. During the following 2 months, she was examined numerous times by neurologists as well as by ear, nose, and throat and pediatric specialists, all of whom concluded that there was no organic cause of the headache. Finally, after the patient suddenly developed signs of abducens nerve palsy, new computed tomography (CT) findings revealed severe temporal bone destruction caused by an inflammatory process. This case report shows the importance of a thorough approach to identify headaches in children. Additional attention must be applied when examining a child with prolonged symptoms of headaches that do not subside with standard therapy.
