Understanding a 5mm Low Attenuation Lesion in the Liver: Causes & Next Steps
A 5 mm low-attenuation lesion in the left hepatic lobe appears darker than surrounding liver on CT/ultrasound, indicating reduced tissue density. Though small, it warrants evaluation.
Possible Causes
- Benign: Cysts, focal fatty infiltration, hemangiomas.
- Malignant: Hepatocellular carcinoma (HCC) or metastases.
Next Steps
Definitive diagnosis requires additional imaging, blood tests, or biopsy. Consult a gastroenterologist or hepatologist for appropriate workup and management based on findings and overall health.
