Focal eosinophilic necrosis versus metastasis in the liver: the usefulness of two-phase dynamic CT

Jin Hur et al. AJR Am J Roentgenol. 2005 Apr.

Abstract

Objective: The purpose of our study was to evaluate the usefulness of dual-phase dynamic CT in the differentiation of focal eosinophilic necrosis of the liver and metastasis.

Conclusion: Undetected isoattenuating lesions on arterial phase images that have an indistinct margin, a nonspherical shape, and a homogenous enhancement pattern on portal venous phase images suggest focal eosinophilic necrosis rather than metastasis. Two-phase dynamic CT was found to be useful at differentiating focal eosinophilic necrosis from metastasis.
