FIG 2. Patient 1. Right SDE and left RSE.
A, Axial T1WI (650/14) shows intermediate signal intensity in the right SDE and hypointensity in the left RSE.
B, Axial T2WI (6000/99) shows high signal intensity in both subdural collections. Strands of intermediate signal intensity (arrows) are noted in the right SDE.
C, Axial contrast-enhanced T1WI (800/20) with MT shows peripheral enhancement of both subdural collections. The enhancement is thicker in the right SDE (arrows) than in the left RSE (arrowheads).
D, Axial DWI (4000/110, b = 1000 s/mm2) shows mixed high (arrows) and low signal intensities in the right SDE.
E, Corresponding ADC map shows mixed low (arrows) and high signal intensities in the right SDE, indicating heterogeneous water motion. Increased water motion is noted in the left RSE.
