Area of Science:

  • Hepatology
  • Medical Imaging
  • Radiology

Background:

  • Macronodular hepatic deformity occurring in a normal liver is an exceptionally rare condition.
  • This study presents nine cases to characterize the clinical and ultrasound findings associated with this rare hepatic abnormality.

Purpose of the Study:

  • To define the characteristic clinical and ultrasound findings of macronodular hepatic deformity on a normal liver.
  • To assist sonographers in differentiating this rare condition from more common hepatic deformities.

Main Methods:

  • Retrospective analysis of nine cases with macronodular hepatic deformity on normal liver.
  • Detailed evaluation of clinical presentation and ultrasound (US) findings, including color Doppler.
  • Correlation of US findings with laparoscopic evaluations.

Main Results:

  • Macronodular hepatic deformity presented with multiple nodules, often involving significant atrophy of certain liver segments.
  • Nodules typically displayed homogeneous internal structure and were isoechoic to surrounding parenchyma on US.
  • Ultrasound findings corresponded to multiple regenerative nodules, with patent major intrahepatic vessels confirmed by color Doppler and angiography.

Conclusions:

  • Macronodular hepatic deformity on a normal liver exhibits a characteristic ultrasound appearance.
  • Recognizing these specific US characteristics is crucial for accurate sonographic differentiation from other hepatic conditions.
