This case report highlights a case of extranodal NK/T cell lymphoma initially misdiagnosed as myositis, emphasizing the appearance on both MRI and FDG PET images. The patient presented with systemic symptoms and calf muscle swelling, prompting imaging studies that revealed diffuse muscle involvement. Despite negative myositis markers and inconclusive biopsy, post-amputation findings confirmed lymphoma with EBV positivity. The appearance in both MRI and FDG PET complicated the diagnostic process, underscoring the importance of considering lymphoma in cases of muscle-related symptoms to prevent delays in appropriate management. This case contributes to the understanding of the diagnostic challenges associated with extranodal NK/T cell lymphoma and emphasizes the significance of peripheral band-like features in imaging studies.
本病例报告强调了一例最初误诊为肌炎的结外 NK/T 细胞淋巴瘤病例，重点介绍了 MRI 和 FDG PET 图像上的表现。该患者出现全身症状和小腿肌肉肿胀，促使进行影像学研究显示弥漫性肌肉受累。尽管肌炎标志物阴性且活检结果不确定，但截肢后的结果证实了 EBV 阳性的淋巴瘤。MRI 和 FDG PET 的表现使诊断过程复杂化，强调了在出现肌肉相关症状时考虑淋巴瘤的重要性，以避免延误适当的治疗。本病例有助于了解与结外 NK/T 细胞淋巴瘤相关的诊断挑战，并强调了影像学研究中周边带样特征的重要性。
