A 64-year-old female with previously surgically treated pancreatic adenocarcinoma now presenting with a hypoechoic focal liver lesion detected in outside US. Clinically the patient was in complete remission for her tumor and her prior abdominal scan was normal. She was asymptomatic and had no fever. a Axial plane T2W MR image demonstrates a moderately hyperintense focal lesion (arrows) in the right liver lobe. b Axial plane postcontrast T1W MR image at the late arterial phase demonstrates marked ring enhancement in the periphery of the lesion (arrows) which was considered to be highly suspicious for an adenocarcinoma metastasis. Percutaneous biopsy did not demonstrate any neoplastic cells but was interpreted as an abscess. Follow up CT scan (not shown) after intense IV antibiotic treatment showed complete disappearance of the lesion
