ABSTRACT

Purpose: Characterize focal hepatic lesions detected and evaluated by multiphase MDCT.
Material and methods: A retrospective, descriptive, double blind study was conducted, which reviewed 64 multiphase MDCT abdominal studies performed at our hospital in the period from February 2010 through February 2011.
Results: 27 (58%) men and 37 (42%) women were obtained, with average age of 51.2 years. the most common benign hypervascular lesion was hemangioma, found in 13 cases (20%), and the most common malignant hypervascular lesion was hepatocarcinoma, found in 12 cases (18.7%); the most common benign hypovascular lesion was simple hepatic cyst found in 6 cases (9.3%), and the most common malignant hypovascular lesion was metastatic lesion, found in 6 cases (9.3%); the most common pseudotumoral lesion was liver abscess, found in 11 cases (17.1%). The right hepatic lobe was the most affected, in 46 cases (72%). Additional findings were identification of arteriovenous fistulas in hemangiomas and in HCC, appearance of portal thrombosis, and changes due to associated hepatopathy.
Conclusions: Multiphase MDCT is the best method of choice for characterization of focal hepatic lesions.
