Pituitary apoplexy present with different MR features, including hemorrhagic and non-hemorrhagic characteristics on T1-weighted images. Pituitary apoplexy is a clinical syndrome that usually results from infarction of, or hemorrhage into, a pituitary macroadenoma. Method of classification based on tumor size and degree of invasion Important for planning of surgical resection . Lateral view of the skull demonstrates expansion of the pituitary fossa.The sella is expanded and contains multiple foci of hyperdense material, particularly peripherally, in keeping with hemorrhage, possibly into a mass. All patients had transsphenoidal pituitary surgery after MR studies. Investigations revealed complete obstruction of the left internal c… You can also search for this author in The gland is replaced by a lesion which is predominantly isointense on T1 with some peripheral areas of T1 hyperintensity corresponding with hyperdensity on CT. Heterogenous T2 signal, predominantly hyperintense with hypointense foci posterosuperiorly, correlating with T1 hyperintensity and consistent with blood product. In this clinical context, features are consistent with pituitary apoplexy. There is minimal viable tissue for histological assessment. The enlargement of the pituitary fossa, however, suggests that a macroadenoma is most likely.
