Osteoid osteomas are benign primary bone lesions characterized by a central nidus with surrounding reactive sclerosis, classically presenting as worsening nocturnal pain relieved by non-steroidal anti-inflammatory medications (NSAIDs). These most commonly occur in intracortical bone and the diaphysis of long bones. As a rare entity, intra-articular osteoid osteomas present unusually, often resulting in a delayed or incorrect diagnosis. We present a case of an intra-articular osteoid osteoma, emphasizing the importance of MRI in aiding diagnosis in this atypical location.
骨样骨瘤是一种良性原发性骨病变，其特征为中央瘤巢伴有周围反应性硬化，典型表现为夜间疼痛加剧，非甾体类抗炎药（NSAIDs）可缓解。这些病变最常发生于皮质内骨和长骨骨干。作为一种罕见的实体，关节内骨样骨瘤表现异常，常导致诊断延迟或错误。我们报告一例关节内骨样骨瘤病例，强调磁共振成像（MRI）在辅助诊断这种非典型部位病变中的重要性。
