Speckled anterior horn of lateral meniscus

The speckled appearance of the anterior horn of lateral meniscus is a feature that can be seen as a normal variant on MRI scans. It is usually seen near its central attachment site. It is often explained by fibers of the anterior cruciate ligament and the covering synovium inserting into the meniscus root giving it a striated appearance.

Radiographic appearance

MRI

It can be seen on one or two of the most medial sagittal images with the meniscus having a speckled nature.
