Solitary necrotic nodule of the liver mimicking hepatocellular carcinoma: a case report

INTRODUCTION: Solitary necrotic nodule of the liver is a rare lesion, with similar radiologic findings to those of hepatic metastases or other liver masses. CASE PRESENTATION: We here report a case of a 30-year-old male with hepatic solitary necrotic nodule discovered after an episode of acute abdominal pain and high grade fever. Routine laboratory data revealed leukocytosis and abnormal liver function. The imaging features of the lesion suggested malignancy or liver adenoma. The patient underwent surgical resection of segments V and VI. Histology was compatible with solitary necrotic nodule and localized vein thrombosis at the periphery. CONCLUSION: Solitary necrotic nodule of the liver is a benign lesion which can mimic liver malignancies. Abdominal imaging and liver biopsy are often equivocal. In such circumstances liver resection is mandatory to exclude HCC or other malignant liver lesions.
