Ghost meniscus

A ghost meniscus, also known as the 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 even a complete absence of the meniscus when there is a large-sized defect.
