Reason: Sudden onset loss of smell, evaluate olfactory nerve History: anosmia, evaluate olfactory nerve The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially including olfactory region. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate mild mucosal thickening in the left maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
MRI of the brain is within normal limits. No intracranial lesion is appreciated which can explain the patient's symptoms.
