L’évaluation IRM comprenait la discrimination d'anomalies dans les articulations, les os et les tissus mous. Deux radiologues musculosquelettiques ont examiné en consensus les résultats IRM de 11 patients atteints de PCM ostéoarticulaire prouvée microbiologiquement et/ou histologiquement. MéthodesĮtude rétrospective de séries de cas, après approbation du comité d’éthique. Abstract frĭécrire les résultats de l'imagerie par résonance magnétique (IRM) dans la paracoccidioïdomycose (PCM) musculosquelettique. Osteomyelitis was the most common presentation, often with secondary involvement of joint and or soft tissue. Musculoskeletal involvement was the primary presentation of the disease in most cases, and therefore, neoplasms were initially in the differential diagnosis. To our knowledge, this is the first case series describing MRI findings of musculoskeletal PCM. Lipomatosis arborescens was documented in one case of chronic knee involvement. Synovial enhancement was present in all cases of joint involvement (6/6). Post-gadolinium images showed peripheral (8/9) or heterogeneous (1/9) enhancement. T2-weighted images showed reactive soft tissue oedema in eight cases (72%). Penumbra sign was present in five cases (45%). All cases showed regions with signal intensity higher than or similar to the signal of muscle on T1-weighted images. Isolated extra-articular soft tissue PCM was found in three patients: myositis (2) and subcutaneous infection (1). Primary arthritis was found in one patient (9%). Osteomyelitis was the most common presentation, with seven cases (63%). Musculoskeletal involvement was the only or the primary presentation of the disease in seven patients (63%). Mean age of patients was 29 years (10–55 years), eight men and three women. The MRI evaluation included discrimination of abnormalities in joints, bones and soft tissues. Two musculoskeletal radiologists reviewed in consensus the MRI findings of 11 patients with microbiologically and/or pathologically proven osteoarticular PCM.
