case_images: (a) A well-defined extra-axial lesion is identified anterior to the brainstem on this sagittal view, appearing hyper intense relative to brain parenchyma on the T2 weighted image (White arrows). (b) Similar section noted one year later with reduction in mass of the cystic lesion identified in the image a

case_images: MRI brain with and without contrast. MRI brain showed a midline prepontine cyst with signals identical to cerebrospinal fluid (CSF) on T1 and T2-weighted images [Figures 1a, 2a and 3a]. Repeat imaging showed a significant size reduction and decrease in mass effect [Figure 1b, 2b and 3b].
