Abstract

Introduction: The imaging diagnostics of liver tumor are difficult. There are no effective biopsy examinations for liver tumors that cannot be detected even by ultrasonography (US) and computed tomography (CT). We report a remarkably useful biopsy method for such tumors. Presentation of case: A 67-year-old man with hepatitis C underwent gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging, and the images revealed multiple delayed enhanced masses that showed high signal intensity in the hepatobiliary phase. The possibility of malignancy could not be ruled out due to the trend towards increased size of the masses. Percutaneous liver biopsy was considered impossible because CT and US could not detect the masses. Laparoscopic liver biopsy with preoperative simulation using 3D imaging was performed. The 3D imaging provided accurate information of liver surface irregularities with cirrhosis change. The tumor location was confirmed, and adequate tumor excisional biopsy was performed. Histological assessment revealed the tumor to be a focal nodular hyperplasia-like nodule. Discussion and conclusions: Laparoscopic liver biopsy has been widely used because of its safety and accuracy. It enables accurate resection of tumors that are undetectable with CT and US by employing preoperative 3D imaging while maintaining the less-invasiveness.
