The term "ghost meniscus", also known as empty meniscus sign, refers to a large radial tear that has completely transected the meniscus or, alternatively, previous meniscectomy.

Radiographic features

MRI

On MRI knee when the slice plane is exactly in line with the meniscal tear this can produce either reduced signal of the involved meniscus from partial volume averaging or complete absence of meniscus when there is a large size defect.
