Figure 6

Meckel’s cave and pituitary stalk involvement of acute lymphoblastic leukemia. (A) Axial STIR T2W image shows well-defined nodular lesions in the bilateral Meckel’s caves (red arrows) with isointense signal relative to the cerebral cortex. (B) DWI image demonstrates mild restricted diffusion in the lesions. (C) Axial and (D) coronal fat-suppressed postcontrast images reveal homogeneous enhancement of the lesions. There is a nodular lesion in the pituitary stalk with similar signal characteristics (blue arrow).
