Fig. 3D —17-year-old girl with knee pain after motor vehicle crash.
Sagittal fat-suppressed T2-weighted MR image (3,500/69) of PCL in same imaging
plane as B reveals abnormal thickening with striations
(arrows) of intermediate signal intensity. Intrasubstance signal
intensity appears relatively lower than in B. Anteroposterior
measurement of this vertical segment is 10 mm, which is abnormal. At surgery,
this PCL was described as torn. Patient underwent anterior cruciate ligament,
PCL, and posterolateral corner reconstructions.
