Lateral Femoral Sulcus Sign
"ACL Tear Alert: Lateral Femoral Sulcus Sign on MRI🌟
As a radiologist, I'd like to highlight a crucial MRI finding that can indicate an ACL tear: the Lateral Femoral Sulcus (LFS) sign.🌟
The LFS sign refers to a focal depression or sulcus in the lateral femoral condyle, which can be seen on sagittal MRI images. This sign is highly specific for ACL tears, particularly in the acute setting.⚜️
Why is the LFS sign important?🦾
- High sensitivity and specificity for ACL tears
- Can be seen in the absence of other obvious ACL injury findings
- May indicate a more severe ACL injury
When interpreting knee MRI scans, don't miss this subtle but critical sign!🌟
