AI Article Synopsis
- The study aimed to explore how a specific rim-like enhancement pattern seen on ultrasound affects the treatment success of microwave ablation in patients with colorectal liver metastasis (CRLM).
- It involved analyzing data from 50 patients evaluated using contrast-enhanced ultrasound before undergoing microwave ablation, with radiologists categorizing the enhancement patterns.
- Results showed that patients with the rim-like enhancement pattern had significantly higher rates of cancer progression post-ablation, indicating this pattern is a potential risk factor for treatment outcomes.
Article Abstract
Objective: To investigate the relationship between the rim-like enhancement pattern on pre-ablation contrast-enhanced ultrasound (CEUS) of colorectal liver metastasis (CRLM) and the therapeutic efficacy of percutaneous microwave ablation (MWA).
Methods: Patients with CRLM underwent MWA and were evaluated using CEUS before ablation in our hospital between February 2020 and February 2023 were enrolled in this retrospective study. The enhancement patterns of CRLM were assessed by two radiologists and classified as rim-like enhancement and non-rim-like enhancement patterns. The therapeutic outcomes, including cumulative intrahepatic progression rate and early intrahepatic progression rate, were followed up and analyzed.
Results: Overall, 50 patients with 121 nodules were enrolled. Rim-like enhancement pattern was observed in 18 patients (18/50, 36.0%). The cumulative intrahepatic progression rate was significantly higher in the rim-like enhancement group than the rate in the non-rim-like enhancement group (p = 0.022). The early intrahepatic progression rate in the rim-like enhancement group was also significantly higher than the rate in the non-rim-like enhancement group (12/17, 70.6% vs. 6/24, 25.0%, p = 0.005). The multivariable analysis demonstrated that the rim-like enhancement pattern of CRLM was a significant risk factor associated with early intrahepatic progression after MWA (p = 0.013).
Conclusion: Rim-like enhancement pattern on pre-ablation CEUS of CRLM was associated with a higher risk of intrahepatic progression after MWA.

A 73-year-old man who previously underwent transsphenoidal surgery for a Rathke's cleft cyst presented with headache and fever. Ophthalmological examination revealed the progression of visual impairment. Cerebral magnetic resonance imaging revealed a cystic mass in the sellar and suprasellar regions with rim-like enhancement.
