Patient is a 74-year-old woman with a history of breast carcinoma and known metastatic brachial plexopathy and pulmonary and mediastinal nodal involvement. She had bilateral mastectomies 5 years ago and is currently on chemotherapy. A 6-month follow-up PET/CT study demonstrated no significant interval change in intensity of the previously evident hypermetabolic activity of the brachial plexopathy. However, this activity has extended superiorly and medially involving the right lateral aspect of the epidural space at the C5-6 level, consistent with epidural involvement. In addition, the hypermetabolic activity of the pulmonary and mediastinal metastases has also increased, consistent with interval progression of the disease.
患者为 74 岁女性，有乳腺癌病史及已知转移性臂丛神经病和肺及纵隔淋巴结受累。她在 5 年前接受了双侧乳房切除术，目前正在接受化疗。6 个月的随访 PET/CT 研究显示，先前明显的臂丛神经病高代谢活性无明显的间隔变化。然而，该活性已经向上和向内延伸，累及 C5-6 水平硬膜外右侧外侧，符合硬膜外受累。此外，肺和纵隔转移的高代谢活性也增加了，符合疾病的间隔进展。
