MRI of the left knee. Sagittal MRI slices in T1-weighted sequence (A) and proton density with fat saturation (B), showing a small cystic formation in T1 low signal intensity and PD fat sat high signal intensity, located above the tibial insertion of the ACL. Note: T1 low signal intensity, PD fat sat high signal intensity in the patellar cartilage reflecting patellar chondropathy. (C) Coronal MRI slice in proton density-weighted sequence with fat saturation showing hyperintense signal of the LCA cyst.
