Abstract

Twenty-six-year-old male patient was admitted to the Emergency Service of our hospital due to head trauma after a motor vehicle accident. No intracranial hematoma or fracture line was detected in the patient who was referred to the Neurosurgery Department, and the patient was discharged. Due to the detection of a suspicious lesion in the right petrous apex during subsequent polyclinic controls, the patient was consulted to our clinic. Due to the absence of clinical signs and the settlement of the lesion, operation was not recommended to the patient who was followed-up with a preliminary diagnosis of petrous apex mucocele, and the patient was called to regular controls. The diagnosis of petrous apex lesions is mostly based on radiological examination. In addition to computed tomography and magnetic resonance imaging, diffusion magnetic resonance techniques assist in the diagnosis process.
