Abstract：
Adrenal gland cysts are rare and uncommon manifestations. Mostly asymptomatic, discovered incidentally during radiological studies or at autopsy, or without characteristic symptoms. The spectrum of these entities may include benign cysts or malignant cystic neoplasms. They are classified into four types: pseudocysts, endothelial cysts, epithelial cysts, and parasitic cysts. Though pseudocysts are reported to be the most frequently clinically recognized adrenal cysts in surgical series, endothelial cysts are more frequent in autopsy series. Even with advanced imaging modalities, it is still difficult to differentiate a benign adrenal neoplasm from a malignant one. As a result, getting a definitive diagnosis and starting treatment is challenging. In both symptomatic and asymptomatic cases with a large diameter or increasing sizes during follow-up, or with any abnormality of adrenal hormones, surgery is the treatment of choice in symptomatic. Herein, we present a 47-year-old female with a nonfunctional left adrenal endothelial cyst, who was incidentally found during a computerized tomography scan. The patient presented with left-sided nephritic colic due to renal lithiasis. The objective of this paper is to recall the clinical characteristics and to specify the diagnostic contribution of imaging as well as the therapeutic modalities of this entity.
摘要：
肾上腺囊肿是罕见且不常见的表现。大部分无症状，在放射学研究或尸检中偶然发现，或者没有特征性症状。这些实体的范围可能包括良性囊肿或恶性囊性肿瘤。它们分为四种类型：假性囊肿，内皮囊肿,上皮囊肿,和寄生虫囊肿.尽管据报道假性囊肿是手术系列中临床公认的最常见的肾上腺囊肿，内皮囊肿在尸检系列中更为常见。即使有先进的成像模式，区分良性肾上腺肿瘤和恶性肾上腺肿瘤仍然很困难。因此,获得明确的诊断和开始治疗是具有挑战性的。在有症状和无症状的大直径或在随访期间增加的大小的病例中，或是肾上腺激素异常,手术是对症治疗的选择。在这里，我们介绍了一名47岁的女性，患有无功能的左肾上腺内皮囊肿，在计算机断层扫描中偶然发现的人。由于肾结石，患者出现左侧肾病绞痛。本文的目的是回顾临床特征，并指定影像学的诊断贡献以及该实体的治疗方式。
