AI Article Synopsis
- * However, diffusion-weighted MRI (DW-MRI) identified new sacral bone metastasis, which was later confirmed by histopathology.
- * After surgical removal of the metastasis and the local tumor, tumor recurrence was detected in the same area eight months later, highlighting DW-MRI's superior diagnostic capability for mucinous tumors compared to PET-CT.
Article Abstract
A 56-year-old male patient with locally advanced mucinous rectal cancer underwent neoadjuvant chemoradiotherapy. Follow-up imaging with positron emission tomography-computed tomography (PET-CT) revealed a local response to chemoradiotherapy, whereas diffusion-weighted magnetic resonance imaging (DW-MRI) showed newly presented sacral bone metastasis. Histopathologically confirmed bone metastasis and the local tumor were surgically removed. Repeat DW-MRI revealed tumor recurrence in the sacral excision zone eight months after surgery, which was reconfirmed by histopathology. This case shows the superior imaging ability of DW-MRI in the diagnosis of mucinous tumors in comparison to PET-CT.
