Learning objectives To review the various spectrum of ultrasound presentations of fatty liver sparing To present variable case reports and perform a differential diagnosis of atypical patterns of fatty liver sparing To investigate the clinical guidelines of management of fatty liver sparing as a finding on US
Fatty infiltration of the liver usually has a diffuse pattern.
It may be associated with with focal sparing/ focal fat accumulation. Focal fatty sparing representing normal areas in fatty liver,
appear hypoechoic on sonography. Focal fatty sparing on a background fatty liver are also called ˝skip areas˝ or pseudolesions . Hepatic steatosis can also present as heterogeneous or nonuniform distribution of fat,
consisting in various atypical patterns of distribution. Atypical patterns of FFS...
Findings and procedure details
In this exhibit we provide an illustrated summary of US findings of typical and atypical,
confusing patterns of focal fatty liver and its clinical implications. Patrick- Olivier Decarie et al  identified six patterns of liver steatosis: diffuse- most prevalent,geographic, focal ,
multifocal and perivascular Common patterns of hepatic steatosis include: diffuse fat accumulation diffuse fat accumulation with focal sparing focal fat accumulation in an otherwise normal liver. The...
Fatty liver is a very common US finding but it has many atypical patterns, that can mimic malignancies and cause diagnostic challenges. Patients with FFS discovered incidentally on US mostly require only follow-up. Inconclusive US findings,
where FFS and other benign lesions cannot be ruled out require further work-up. Previous US findings of the liver may be very useful as a reference when a tumorlike abnormality is identified on follow-up sonography. US is the first imaging modality for the...
