List the wide spectrum of fat-containing lesions of the liver and identify the imaging features.
The presence of fat in a hepatic lesion is not an unusual finding.
Identifying the fat is a crucial step in the process of diagnosing aetiology. Although a variety of liver lesions mayshow fat on cross-sectional imaging,
the presence of fat usually indicates that the lesion is of hepatocellular origin. Fat may be macroscopic or microscopic.
MRI is the modality of choice for detecting a fatty component in a hepatic lesion: fat-saturation sequence detects extracellular fat while chemical shift...
Findings and procedure details
The differential diagnosis of a fat-containing liver mass is usually limited to masses of hepatocellular origin. Fat-containing liver lesions of nonhepatocellular origin are less common and may be identifiedby ancillary imaging or clinical features. - Fat-Containing Hepatocellular Lesions Hepatocellular adenomas (HCA) HCAs are uncommon benign tumors, usually encountered in women with a history of oral contraceptive use,
athletes taking anabolic steroids,
or patients with metabolic diseases....
The identification of fat within a liver lesion,
along with other radiological signs and reflection on the clinical and epidemiological context,
can lead to a diagnosis being reached or suggested,
with confirmation if necessary,
by a pathological examination. Although the presence of fat can be documented with CT or US,
MR imaging is the most specific imaging technique for demonstrating both microscopic and macroscopic fat.
