Skeletal muscle involvement by lymphoma is rare, particularly for mantle cell lymphoma. We describe a 65-year-old man who presented with a rapidly growing left thigh mass. FDG PET/CT characterized the mass as malignant. Interestingly, an unusual hypermetabolic elongated tumorous extension was demonstrated arising from the intramuscular mass disseminating alongside the neurovascular bundle of the thigh up to the groin. Histopathology revealed intramuscular mantle cell lymphoma. In this case, we aim to highlight this interesting FDG PET/CT imaging finding, which can serve as a clue allowing one to strongly suggest lymphoma as the leading diagnosis.
淋巴瘤累及骨骼肌较为罕见，尤其对于套细胞淋巴瘤而言。我们描述了一位 65 岁男性，其表现为左侧大腿肿块迅速增大。FDG PET/CT 特征提示该肿块为恶性。有趣的是，该肿块内可见一异常代谢增高的长形肿瘤样延伸，沿大腿神经血管束蔓延，直至腹股沟。组织病理学显示为肌内套细胞淋巴瘤。在本例中，我们旨在强调这一有趣的 FDG PET/CT 影像学发现，这一发现可以作为强烈提示淋巴瘤为主要诊断的线索。
