Parrot beak tear of meniscus
A parrot beak meniscal tear is a type of oblique meniscal tear which is connected in one plane and displaced in the other plane. Its appearance on axial images is curved like a crescent and is likened to that of a parrot's beak. The tear gap has a curved V-shape.
Some authors advise that the term should be reserved for arthroscopy reports, and not used in MRI reports as a meniscal tear pattern descriptor 1.
