Dr Choti and his coauthors have analyzed intraoperative sonographic findings of the liver in 99 consecutive patients with 194 metastatic colon tumors. Echogenicity and sonographic patterns were compared between patients and within each patient. There was notable variability in echogenicity and patterns among the lesions and the only clinicopathologic correlate was that of chemotherapy with a "target" or calcified pattern. Using the 40 patients with multiple tumors, it was found that there was much less variability within each patient (intrapatient variability) than would be expected from the variability between different patients (interpatient variability). Although this seems intuitive, the article clearly and objectively proves the point. There may not have been enough data in this series, but it would have been interesting to see if factors such as preoperative chemotherapy and/or hepatic steatosis correlated with intrapatient differences in sonographic features. The ultimate conclusion . . . [Full Text of this Article]
