Synovial lipomatosis is a benign proliferative disease of the subsynovial adipose which can lead to a variety of presentations. Cases of synovial lipomatosis in children or adolescents are rare. This case report describes an adolescent patient with a rare bilateral presentation of synovial lipomatosis. She had been treated for years prior to her presentation for juvenile idiopathic arthritis. She presented with chronic bilateral knee pain, swelling, and mechanical symptoms. Bilateral MR imaging demonstrated effusions, hypertrophy of the synovium, and polyp-like projections of tissue with the same signal intensity as fat which is pathognomonic for synovial lipomatosis. Arthroscopic synovectomy and extensive debridement of polyp like fat projections of the right knee was performed. Histopathology was consistent with the synovial lipomatosis diagnosis. Postoperatively, the patient was satisfied with her outcome with improved pain relief and function in her right knee.
滑膜脂肪瘤病是一种滑膜下脂肪的良性增生性疾病，可导致多种临床表现。儿童或青少年患滑膜脂肪瘤病的病例罕见。本病例报告描述了一名患有罕见双侧滑膜脂肪瘤病的青少年患者。在她因幼年特发性关节炎就诊之前，已经接受了多年治疗。她表现为双侧膝关节慢性疼痛、肿胀和机械性症状。双侧磁共振成像显示有积液、滑膜肥厚以及与脂肪信号强度相同的息肉样组织突起，这是滑膜脂肪瘤病的特征性表现。对右膝进行了关节镜下滑膜切除术及对息肉样脂肪突起进行广泛清创。组织病理学与滑膜脂肪瘤病的诊断相符。术后，患者对其结果感到满意，右膝疼痛缓解，功能改善。
