Background: Synovial chondromatosis is a rare, benign disorder characterised by neoplastic proliferation of numerous chondral nodules in joint synovium, bursae or tendon sheaths. The disease is usually diagnosed in the third, fourth and fifth decades of life and is twice as common in men. In most cases, it affects one joint but may appear bilaterally (in up to 10% of patients). The most common location is the knee joint. Computed tomography (CT) is the best method for detection of calcified intraarticular bodies. Magnetic resonance imaging (MRI) may also implicate presence of synovial chondromatosis - on T2-weighted images calcifications are visible as focal areas of signal void within hyperintense fluid, with hypertrophic synovium. In addition, this technique may show possible extraarticular disease involvement. Ultrasound examination is an alternative method of imaging of synovial chondromatosis. Case Reports: In this article, we present two cases of synovial chondromatosis. The first patient was a 14-months-old girl with multiple cartilaginous loose bodies in the knee joint detected in ultrasound and MRI examinations. The other patient was a 68-years-old woman with calcification within the shoulder joint demonstrated in CT and MRI examinations. Conclusions: Diagnostic imaging plays an essential role in the diagnosis of synovial chondromatosis, although the final diagnosis is still based on histopathological examination.
