Yehouenou Tessi RT, Oze KR, Imrani K, El Hosni KB, Moatassim Billah N, Nassar I. Etiology of a painful knee: Primary synovial chondromatosis. Int J Case Rep Images 2022;13:101310Z01RT2022.ABSTRACT
Primary synovial chondromatosis is characterized by a benign synovial proliferation associated with a metaplastic process. It remains a rare benign pathology of unknown cause. It evolves in three phases and the diagnosis is most often late. Imaging plays an essential role, particularly conventional radiology, computed tomography (CT)/arthroscan and magnetic resonance imaging (MRI). The imaging findings vary according to the stage. Synovial nodules and intra-articular foreign bodies are found. The knee is the most frequent localization. The treatment is surgical with the contribution of arthroscopy. We report the case of a 36-year-old woman who presented with gonalgia without any notion of trauma and who was diagnosed with primary chondromatosis by MRI with histologic confirmation. The recurrence rate remains low postoperatively and is often due to incomplete removal of synovial nodules and intra-articular foreign bodies.
