We present a rare case of pediatric scurvy in a 9-year-old male who presented with nontraumatic knee pain. MRI was obtained due to the puzzling presentation. MRI demonstrated a systemic bone marrow abnormality which led to a conversation with the clinician and further elucidation of an extremely narrow diet lacking sufficient vitamin C (ascorbic acid). Diagnosis was confirmed biochemically with undetectable ascorbic acid level and clinically with compatible exam and history. This case highlights a thought process for unexpected bone marrow abnormality on MRI.
我们报告一例罕见的小儿坏血病，患儿为一名9岁男性，表现为非创伤性膝关节疼痛。由于临床表现令人困惑，故进行了磁共振成像（MRI）检查。MRI显示全身骨髓异常，这促使与临床医生进行沟通，并进一步明确患儿饮食极度单一，缺乏足够的维生素C（抗坏血酸）。通过生化检查确认抗坏血酸水平无法检测到，并结合相符的体格检查和病史，临床确诊。该病例突出了对MRI上意外骨髓异常的思考过程。
