Diagnosis: Neoplasm of uncertain behavior of pituitary gland and craniopharyngeal ductClinical question: h/o pituitary abnormality; evaluate pituitarySigns and Symptoms: visual field cut brain:The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 5 x 8 mm extra-axial mass present adjacent to the superior sagittal sinus and adjacent to the left superior frontal gyrus.pituitary:There is a mass present in the sella which extends suprasellar and it measures 14 x 13 mm coronal dimensions and 14 x 8 mm sagittal dimensions. It abuts and superiorly displaces the optic chiasm. It does not appear to have any significant cavernous sinus extension. The infundibulum of the pituitary gland is midline. The cavernous sinuses are intact bilaterally.
1.There is a sellar and suprasellar mass which displaces the optic chiasm superiorly. Most likely this represents a pituitary adenoma.2.There is a small subcentimeter extra-axial mass present adjacent to the left superior frontal gyrus which most likely represents a meningioma.
