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.
肝脏钙化在腹部平片（KUB）或血管造影检查的普通X线片上已有广泛描述。另一方面，其特征在横断面成像中很少被报道：与多种其他影像学特征相比，它们常被认为是非特异性的。然而，临床实践表明，在特定情况下（如寄生虫感染和钙化转移瘤），钙化的存在可能是避免对患者产生潜在有害影响的误诊的决定性因素。CT和超声都能检测到大量无相关局灶性病变的“良性”钙化，了解其影像学特征有助于避免不必要的额外影像学检查。本文回顾了文献，并展示了一系列100例CT上肝脏钙化的病例，以回顾钙化性肝脏病变及无相关局灶性病变的孤立性肝脏钙化的影像学特征。
