CT and MRI of the exophytic liver tumor. a Coronal contrast-enhanced CT image of the abdomen at the portal venous phase showing the large exophytic mass originating from the caudal border of liver segments 4B and 5 with a heterogeneous enhancement pattern. b Axial fat-suppressed T2-weighted MR image showing the large tumor with heterogeneous hyperintense signal intensity. c-e Axial fat-suppressed T1-weighted MR images at the arterial (c), portal venous (d), and delayed phase (e), showing slight heterogeneous, predominantly peripheral arterial enhancement, with increasing enhancement at the portal venous and delayed phases. No significant drop of signal intensity was present at the opposed-phase T1-weighted images (not shown).

Hepatocellular adenomas (HCA) are rare benign tumors of the liver, occurring predominantly in females using oral contraceptives. Our case describes a 66-year-old woman presenting with a palpable mass in her upper abdomen. Contrast-enhanced computed tomography and magnetic resonance imaging showed a large exophytic mass protruding from the caudal bo...

... Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) showed a solitary large (about 15 × 20 cm), heterogeneous exophytic mass protruding from the caudal border of liver segments IV and V with a heterogeneous hypervascular enhancement pattern, without clear washout in the portal venous or delayed contrast phases ( Fig. 1). At MRI, the lesion showed a heterogeneous increased signal intensity at T2-weighted images, DOI: 10.1159/000510215 © 2020 The Author(s). Published by S. Karger AG, Basel ...

The prevalence of benign mass-forming liver lesions has significantly increased in recent years due to advances in diagnostic imaging. In general, these lesions can be either neoplastic or nonneoplastic and carry a different prognosis and management. Among benign mass-forming lesions of the liver, hemangiomas are the most common, followed by focal...
