ANSWER
Answer	CBC and differential count
Comments	The imaging findings of eosinophilic abscess or focal eosinophilic infiltration usually appears as small, oval or round, and low attenuating nodules with well- or ill-defined margins. They are most conspicuous during the portal venous phase. They have iso/low, low/low, or mixed attenuation on the hepatic arterial/portal venous phases. However, eosinophilic abscess in the liver can rarely show contrast enhancement during the hepatic arterial phase. If patients have peripheral hypereosinophilia or are at low risk for hepatocellular carcinoma or hepatic metastasis, those with small arterial-enhancing hepatic nodules need further preoperative evaluation, such as a sonographically guided biopsy.
