A radiological footprint equivalent to liquefactive necrosis observed in the course of disappearing liver metastases in rectal cancer: A case report and review of the literature
A 72-year-old female diagnosed with rectal cancer treated with a surgical procedure was reported. As 3 liver metastases (LMs) appeared in multidetector CT, adjuvant chemotherapy using Bevacizumab combined with modified FOLFOX-6 was completed. LMs were changed to cystic lesions during the follow-up p...

| description | A 72-year-old female diagnosed with rectal cancer treated with a surgical procedure was reported. As 3 liver metastases (LMs) appeared in multidetector CT, adjuvant chemotherapy using Bevacizumab combined with modified FOLFOX-6 was completed. LMs were changed to cystic lesions during the follow-up period, consistent with liquefactive necrosis. These cystic lesions that appeared in the course of disappearing LMs (DLMs) were identified by CT as homogeneous low signal intensity in hepatocyte specific Gd-enhanced MRI. This might be pathognomonic radiological footprint equivalent to liquefactive necrosis observed in the process of DLM and must be carefully followed in the course of radiological complete response. The radiological changing findings of LMs to cystic changes, high sensitivity of detecting DLM, and limitations of Gd-MRI might be meaningful to clinicians. |
