Benign neoplasm of pituitary gland and craniopharyngeal duct ( The CSF spaces are appropriate for the patient's stated age with no midline shift. There is redemonstration of a millimeter-sized lesion along the left pituitary gland lobe superiorly which does not enhance.No abnormal enhancing mass lesions are appreciated intracranially. 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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is redemonstration of a small nonenhancing focus along the superior aspect of the left pituitary gland lobe. One possibility is that this represents a microadenoma. It is better characterized on the prior exam.2.Please note that this exam is made for the purpose of stereotactic guidance.
