Diagnosis: Benign neoplasm of pituitary gland and craniopharyngeal duct (pouch)Clinical question: h/o pituitary adenoma; preop planningSigns and Symptoms: preop planning The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 29 x 21 mm axial dimension mass located within the sella eccentric towards the left side with the suprasellar extension and extension into the left cavernous sinus which abuts the optic chiasm and of the left internal carotid artery. It partially surrounds the left internal carotid artery. It does not appear substantially different than on the prior exam.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.
This is a limited exam for the purpose of stereotactic guidance during surgery. There is a sellar and suprasellar mass present which presumably represents a pituitary adenoma. It abuts the adjacent optic chiasm.
