It was exhibiting a pressure effect on the adjacent brain parenchyma (Figure 1).
MRI images obtained in January 2014. (A) Axial T1, (B) axial T2, (C) sagittal T2, (D) axial FLAIR, (E) axial DWI, (F) axial ADC.

Apparent Diffusion Coefficient (ADC) images (Figure 2). Moreover, a decrease in the size of the arachnoid cyst as a result of rupture into the subdural space was noted (Figure 2D-2F). An MRI scan of the unoperated but monitored patient was performed in February 2015; a minimal reduction in effusion thickness was observed, with no significant differences observed on the MRI images (Figure 3).
