Abstract

Objective To determine the prevalence of liver cysts and hemangiomas in the general population and in cirrhotic patients. Materials and Methods Retrospective, observational, and cross-sectional study selecting consecutive magnetic resonance imaging studies performed in the period from February to July 2011. A total of 303 patients (187 women and 116 men) with mean age of 53.3 years were included in the present study. Patients with previously known liver lesions were excluded. The images were consensually analyzed by two observers in the search for simple liver cysts and typical liver hemangiomas, according to universally accepted imaging criteria. Lesions prevalence, diameters and location were determined in both cirrhotic and non-cirrhotic individuals. Results The authors observed prevalence of 8.6% for hemangiomas and 14.5% for simple cysts. No statistically significant difference was observed in relation to prevalence of hemangiomas and cysts among cirrhotic and non-cirrhotic patients (p = 0.954; p = 0.472). Conclusion In the present study, the prevalence of cysts and hemangiomas was higher than the prevalence reported by autopsy series. No influence of cirrhosis was observed on the prevalence and appearance of such incidental lesions.Objetivo Determinar a prevalência de cistos e hemangiomas hepáticos na população geral e em pacientes cirróticos. Materiais e Métodos Estudo retrospectivo, observacional e transversal selecionando exames consecutivos de ressonância magnética de abdome realizados entre fevereiro e julho de 2011. Foram incluídos 303 pacientes (187 mulheres e 116 homens) com idade média de 53,3 anos, excluindo-se os com lesão hepática previamente conhecida. Os exames foram lidos por dois examinadores em consenso, procurando caracterizar cistos hepáticos simples e hemangiomas típicos segundo critérios de imagem universalmente aceitos. Foram medidos a prevalência das lesões, seus diâmetros e localização em pacientes com e sem cirrose hepática. Resultados Encontrou-se prevalência de 8,6% para hemangiomas e 14,5% para cistos simples. Não houve diferenças estatisticamente significativas nas prevalências de hemangiomas e cistos entre pacientes cirróticos e não cirróticos (p = 0,954; p = 0,472). Conclusão As prevalências encontradas de cistos e hemangiomas foram mais altas que as das séries de autópsias. Não houve influência da presença de cirrose na prevalência e aspecto dessas lesões incidentais.
