Summary
Computed tomography (CT) effectively detects hepatic metastases, often revealing multiple nodules in the liver parenchyma. This imaging technique is valuable for diagnosing liver metastases, even small ones.
Area of Science:
- Radiology
- Oncology
- Hepatology
Background:
- Hepatic metastases are secondary malignant tumors in the liver.
- Accurate diagnosis of liver metastases is crucial for patient management.
Purpose of the Study:
- To characterize the imaging manifestations of hepatic metastases.
- To evaluate the diagnostic utility of computed tomography (CT) for hepatic metastases.
Main Methods:
- Retrospective analysis of CT scans from 90 patients diagnosed with hepatic metastases.
- Detailed assessment of tumor characteristics including number, size, density, shape, and distribution.
- Measurement of liver and spleen size.
Main Results:
- Multiple metastatic nodules (≥3) were observed in 72% of cases.
- Nodule sizes ranged from 0.5 cm to 14 cm, with lower CT density than surrounding liver parenchyma in most cases.
- Hepatomegaly was noted in 31 cases, while 45 cases showed concurrent detection of primary tumors via CT.
Conclusions:
- CT findings for hepatic metastases are variable, but multiple nodules disseminated throughout the liver parenchyma are a common sign.
- CT is capable of detecting small hepatic metastases, even in the absence of other clinical indicators.
