[Case of solitary necrotic nodule of the liver difficult to distinguish from malignant hepatoma].

ABSTRACT

In a 72 years old woman, abdominal computed tomography (CT) disclosed multicentric hypervascular tumor in S4 of the liver, and it was T1.T2 by the MRI, and a high signal was presented together. Stenosis was shown by ERCP at the same site. Cholangiocellular carcinoma was suspected before operation, but malignant change was not recognized by frozen section, so the operation was finished. Later, a diagnosis of solitary necrotic nodule of the liver was established by pathological diagnosis. Solitary necrotic nodule of the liver is a benign tumor.
