Diagnosis and Treatment of a Lateral Meniscal Cyst with Musculoskeletal Ultrasound

Abstract EN

Meniscal cysts are a relatively uncommon occurrence that may result in pain and disability in the knee.

It is widely believed that meniscal cysts are secondary to fluid extrusion from a meniscus tear.

Typically, diagnosis of a meniscal cyst typically requires magnetic resonance imaging (MRI) to delineate the cyst and any associated injuries.

With improvements in sonographic technology, ultrasound has emerged as a sensitive modality for detection of meniscal cysts.

We present a patient with a contraindication to MRI who was diagnosed with a lateral meniscal cyst by musculoskeletal ultrasound and treated with an ultrasound-guided lateral meniscal cyst aspiration and injection.
