Case in brief
A 57-year-old Asian male presented with a rectal mass and multiple distinct liver lesions. Contrast-enhanced ultrasound (CEUS) suggested the presence of both colorectal cancer liver metastasis and hepatocellular carcinoma. This was confirmed histologically through an ultrasound-guided biopsy, highlighting the effectiveness of CEUS in diagnosing complex liver lesions.
What made this case unusual
This case is notable for the co-occurrence of colorectal cancer liver metastasis and hepatocellular carcinoma in a single patient, which has not been previously reported.
Diagnostic / clinical pearl
Clinicians should consider the utility of contrast-enhanced ultrasound in differentiating between complex liver lesions, particularly when multiple pathologies may coexist.
Why it matters
This case emphasizes the importance of targeted biopsy for accurate diagnosis in patients with multifocal liver lesions, which can significantly impact management strategies.
