摘要
Simple liver cysts are congenital with a prevalence of 2.5%-4.25%. Imaging, whether by US, CT or MRI, is accurate in distinguishing simple cysts from other etiologies, including parasitic, neoplastic, duct-related, and traumatic cysts. Symptomatic simple liver cysts are rare, and the true frequency of symptoms is not known. Symptomatic simple liver cysts are predominantly large （〉 4 cm）, right-sided, and more common in women and older patients. The vast majority of simple hepatic cysts require no treatment or follow-up, though large cysts （〉 4 cm） may be followed initially with serial imaging to ensure stability. Attribution of symptoms to a large simple cyst should be undertaken with caution, after alternative diagnoses have been excluded. Aspiration may be performed to test whether symptoms are due to the cyst; however, cyst recurrence should be expected. Limited experience with both laparoscopic deroofing and aspiration, followed by instillation of a sclerosing agent has demonstrated promising results for the treatment of symptomatic cysts. Here, we describe a patient with a large, symptomatic, simple liver cyst who experienced complete resolution of symptoms following cyst drainage and alcohol ablation, and we present a comprehensive review of the literature.
简单的肝包囊与 2.5%-4.25% 的流行是先天的。成像，是否由美国， CT 或 MRI，在把简单包囊与另外的病原学区分开来是精确的，包括寄生，肿瘤，管相关，并且创伤性囊肿。征兆的简单的肝包囊是稀罕的，并且症状的真频率不被知道。征兆的简单的肝包囊主要大(> 4 厘米) ，在女人右边、更普通、更老的病人。绝大多数简单肝的包囊不要求治疗或后续，尽管大包囊(> 4 厘米) 可以开始与连续成像被跟随保证稳定性。到大简单包囊的症状的归属应该小心地被承担，在选择诊断以后被排除了。渴望可以被执行测试症状是否由于包囊；然而，包囊复发应该被期望。有 laparoscopic deroofing 和渴望的有限经验，由一个致硬化的代理人的灌输列在后面为征兆的包囊的治疗表明了有希望的结果。这里，我们与大、征兆的、简单的肝包囊描述一个病人经历了症状的完全的分辨率后面的包囊排水和白酒脱离，和我们在场文学的全面评论。
