| Abstract: | The magnetic resonance imaging (MRI) in a female patient who presented with headache and hearing loss revealed aberrant course of the petrous segment of internal carotid artery (ICA). Computed tomography (CT) of the temporal bone done to confirm the findings of MRI revealed aberrant course of right ICA, a persistent stapedial artery (PSA) and absent foramen spinosum on the same side. In addition patient had a cystic cochleovestibular anomaly on the right side with both conditions may probably be contributing to her hearing loss. |
