Benign neoplasm of pituitary gland [D35.2] / Benign neoplasm of craniopharyngeal duct [D35.3], OSH questionable lesion to Pituitary. Headaches. There is a 4 mm diameter hypoenhancing ovoid lesion in the right superior pituitary gland suspicious for pituitary microadenoma. The pituitary gland also appears slightly enlarged overall, measuring up to 10 mm. The pituitary exerts mild mass effect on the optic chiasm and pituitary stalk. The posterior pituitary T1 bright spot an perhaps slightly prominent. There is prominence of the visualized lateral and third ventricles and the partly imaged cerebellum appears to be somewhat dysmorphic.
1. A 4 mm diameter lesion in the superior right pituitary gland may represent pituitary microadenoma.2. Prominence of the visualized lateral and third ventricles and possible dysmorphic appearance of the partly imaged cerebellum may be developmental in nature. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
