Résumé
Liver calcifications have been extensively described on plain radiographs, either from KUB or angiography examinations. On the other hand, their characteristics are seldom reported on cross-sectional imaging : they are frequently considered as non-specific compared to multiple other imaging features. However, clinical practice demonstrates that in specific situations (such as parasitic infections and calcified metastases), the presence of calcifications may be a determining factor in avoiding misdiagnosis with potential deleterious effects to the patient.
Both CT and US can detect a large number of "benign" calcifications without associated focal lesion and knowledge of their imaging features is useful to avoid unnecessary additional imaging work-up.
A review of the literature and a series of 100 cases of liver calcifications on CT are presented to review the imaging features of calcified liver lesions and isolated liver calcifications without associated focal lesion.
