Figure 2. Cysts.

Figure 2

T1-weighted axial images (A, D) show single unilocular interhemispheric supratentorial arachnoid cysts (white arrow), with CSF-like signal (type 2d according to the Barcovich classification); in (D), associated with an infratentorial arachnoid cyst (*). T1-weighted axial images (B, C) show multilocular (black arrow, B) and unilocular (dashed white arrow, C) supratentorial interhemispheric cysts with hyperintense to CSF signal (type 2b according to the Barcovich classification), probably glioependymal cysts. T2-weighted axial images (E, F) show choroid plexus cysts (asterisk, E) and papillomas (asterisk, F).
