A 28-year-old man with headache, nausea, and decreased vision had a left parieto-occipital tumor demonstrated by MRI. Postradical resection and histology showed a solid mass containing rhabdoid cells, 10% positive for Ki-67. After completing chemotherapy and radiotherapy treatment, follow-up MRI revealed possible tumoral recurrence. Cerebral F-18 FDG PET revealed no pathologic uptake, and C-11 methionine PET showed a pathologic low uptake. These findings suggested recurrence of a mild-grade aggressiveness tumor, which was confirmed by a second neurosurgical resection.
一位 28 岁男性，头痛、恶心并伴有视力下降，MRI 显示左顶枕部肿瘤。根治性切除术后组织学显示为含有横纹肌样细胞的实性肿块，Ki-67 阳性率为 10%。完成化疗和放疗后，随访 MRI 显示可能存在肿瘤复发。脑 F-18 FDG PET 未见病理性摄取，C-11 蛋氨酸 PET 显示病理性低摄取。这些发现提示低度侵袭性肿瘤复发，第二次神经外科切除证实了这一诊断。
