Abstract
|
|
|
|
Solitary necrotic nodule (SNN) of the liver is a very uncommon benign lesion, and it is detected incidentally as a rule. It is important to differentiate SNN radiologically from various single hepatic nodules because SNN mimics hepatic metastasis, especially in staging work up of known primary malignancy. The reported imaging findings of SNN are well-defined nodule without enhancement or with subtle peripheral enhancement. There has been no report about the target-like SNN of the liver and about the imaging finding of 3T magnetic resonance imaging and positron emission tomography. We report a case of targetlike SNN of the liver, mimicking hepatic metastasis, with findings of various imaging modalities and try to find a cause of this nodule according to the pathologic and literature review.
