Abstract

Both chest radiography and MRI scan showed compression fracture of the T6 vertebral body in a 33-year-old man who presented with back pain. Because of the absence of predisposing factors for compression fracture, a pathologic fracture was considered. For this reason, an FDG PET/CT was performed. The images revealed not only the abnormal activity in the known T6 vertebral body but also an additional activity immediately anterosuperior to the urinary bladder in a partially calcified soft tissue nodule. A mucinous adenocarcinoma of urachus with solitary bone metastasis was confirmed histopathologically.

摘要

胸部 X 光和 MRI 扫描均显示一名 33 岁男子 T6 椎体压缩性骨折，该男子背痛。由于没有导致压缩性骨折的诱发因素，考虑为病理性骨折。因此，进行了 FDG PET/CT 检查。图像不仅显示了已知 T6 椎体的异常活动，还显示了膀胱前上方一个部分钙化的软组织结节中有额外的活动。组织病理学证实为脐尿管黏液性腺癌伴单发骨转移。
