Pediatric solitary plasmacytomas are extremely rare, with only 14 cases previously reported. None of these reports included PET imaging findings. We present PET/CT and PET/MRI imaging findings in a 15-year-old boy with what was initially thought to be a solitary plasmacytoma, which later developed into multiple myeloma. The initial PET/CT of solitary plasmacytoma, as well as postradiotherapy PET/MRI findings with the new lesions suggestive of multiple myeloma, are presented.
儿童孤立性浆细胞瘤极为罕见，既往仅报道过 14 例。这些报道均未包括 PET 成像结果。我们报告了 1 例 15 岁男孩的 PET/CT 和 PET/MRI 成像结果，该男孩最初被认为患有孤立性浆细胞瘤，后来发展为多发性骨髓瘤。我们呈现了孤立性浆细胞瘤的初始 PET/CT 以及新病灶有提示多发性骨髓瘤的放疗后 PET/MRI 结果。
