Pre- and postoperative MRI images. A High-density areas on T2WI (left column) are observed around the right thalamus lesion, with invasion of the right pedunculus cerebri. Lesions in the right thalamus and hypothalamic–pituitary axis have been shown on contrast-enhanced T1WI (right column). There is thickening of the pituitary stalk. B Postbiopsy contrast-enhanced T1WI targeting the right thalamus demonstrates the correct biopsy (scar due to biopsy indicated by red wedge arrows). Hypothalamic–pituitary axis lesions are indicated by red arrows
