Enlarging hepatic lesion seen on CT. Question if cyst. LIVER: Non-cirrhotic liver morphology. Normal parenchymal echogenicity. The segment 6 hepatic lesion measures approximately 3.6 x 3.4 x 3.3 cm. The lesion contains heterogeneous internal echogenicity with peripheral hypoechogenicity. There is no internal vascularity. No intrahepatic biliary ductal dilation is seen.OTHER: No significant abnormalities noted on this limited examination.
3.6 cm hepatic segment 6 mass, with characteristics excluding a benign cyst. The appearance of this mass may represent an abscess with echogenic debris or a necrotic soft tissue mass such as a metastasis. In the presence of known abscesses and absence of known primary malignancy, an abscess is favored.
