Computed tomography in hepatic metastases

Ananthakumar P and Adaikkappan M

Background: The liver is one of the most common organs to be involved with metastatic disease, which arises most frequently from primary sites in the colon, breast, lung, pancreas, and stomach. The accurate detection of metastatic disease at the time of diagnosis or during the course of treatment remains crucial to patient management.
Objective: To evaluate the effectiveness of computed tomography in detecting hepatic metastases in patients with focal liver lesions and to provide information regarding probable source of primary lesions.
Materials and methods: The study was conducted in the department of Radio diagnosis, Rajah Muthiah Medical College, Chidambaram. Forty patients with hepato-biliary related clinical symptoms or incidentally detected liver masses with USG abdomen were evaluated. Of them, 11 patients with metastases were included in this study. Rest of the patients with other focal lesions was excluded from the study.
Results: Out of 40 patients, 11 patients diagnosed with hepatic metastases underwent histopathological examinations. Six patients had stomach carcinoma, two had thyroid malignancy, one patient each had lung, renal and pancreatic carcinoma.
Conclusions: CT scanning, which is widely available and familiar, remains the dominant modality in the evaluation of suspected hepatic metastases, for preoperative planning and treatment monitoring.
