case_images: The first magnetic resonance imaging examination confirmed a sellar and suprasellar mass iso-hyperintense to the brain tissue on T1 and T2 weighted images with an hypointense area on T2*Fast Field Echo images as hemosyderin component (black arrow) in possible subacute bleeding. After intravenous injection of gadolinium, an evident ring sign, thickening of the pituitary stalk, and infundibulum and dural tail sign (red arrow) have been detected; an evident sphenoidal mucosal thickening is also present.

case_images: Due to the rapidly worsening condition, a cerebral gadolinium-based contrast magnetic resonance imaging (MRI) revealed a pituitary mass with signs of bleeding consistent with PA (Fig. 1). In addition, there was a loss of posterior pituitary T1 high signal intensity [posterior pituitary high intensity (PPHI)] on the sagittal T1 plane sequences and an intense and homogeneous enhancement of the infundibulum, a thickening of the pituitary stalk (6.5 mm), and a dural tail sign, suggesting a PA with possible concomitant radiological signs of AH (Fig. 1).
