High-Resolution Ultrasonography Diagnosis of Meniscal Cyst from Lateral Meniscus

Meniscal cyst is a rare pathology that may present clinically with pain or mechanical symptoms in and around the knee joint. It results from encysted & extruded synovial fluid through meniscal tear usually secondary to trauma. It is best delineated on magnetic resonance imaging of knee joint which provides a noninvasive diagnosis but is non-therapeutic. However, with the availability of ultramodern ultrasound scanner, it is now possible to diagnose meniscal cyst accurately by high-resolution ultrasonography which also provides a possibility of therapeutic procedure. Hence in this article, we try to emphasize the diagnostic value of high-resolution ultrasonography in rare meniscal cyst pathology of knee joint.
