Magnetic resonance imaging is the modality of choice for diagnosis of<unk> s. In their most subtle form,<unk> s present as focal areas of high signal intensity within a swollen meniscus. It is not uncommon for radiologists to miss this type of<unk>  because the signal intensity is not quite as great as fluid on T2 weighted sequences.2 When this fluid is extruded into the adjacent soft tissues, the swollen meniscus subsequently assumes a more normal shape, and the extruded fluid demonstrates a higher T2 signal typical of parameniscal<unk> s.
