The gallbladder is affected by a large number of congenital anomalies, which may affect its location, number, size, or form. Some of these malformations are very rare and may lead to misdiagnosis. An ectopic gallbladder can be misinterpreted as agenesis of the organ or as a cystic hepatic mass when intrahepatic. Given the frequency and the wide acceptance of the ultrasonographic examination of the biliary tract, radiologists should be aware of these malformations. In some cases, ultrasonographic diagnosis can be difficult. However, the use of Computed Tomography can elucidate such cases. We present the case of a patient whose gallbladder had two combined malformations but caused no symptoms. Namely, the patient had a transverse ectopic gallbladder combined with a "Phrygian cap" deformity. The incidence of ectopic locations of the gallbladder is 0.1-0.7%, whereas the "Phrygian cap" deformity can be found in 4% of patients. There is no other cases with combination of these two entities reported in the literature. Ultrasonographic and CT findings are presented and aspects of this malformation are discussed. The clinical significance of ectopic gallbladder is also emphasized because it may alter the clinical presentation of biliary tract diseases and pose technical problems during surgery.
胆囊会受到大量先天性异常的影响，这些异常可能会影响其位置、数量、大小或形态。其中一些畸形非常罕见，可能导致误诊。异位胆囊在肝内时，可能会被误诊为器官发育不全或肝内囊性肿块。鉴于超声检查胆道的频率高且被广泛接受，放射科医生应了解这些畸形。在某些情况下，超声诊断可能会很困难。然而，使用计算机断层扫描可以阐明此类病例。我们报告一例患者，其胆囊有两种合并畸形，但未引起任何症状。具体而言，该患者有横向异位胆囊合并“Phrygian帽”畸形。胆囊异位的发生率为0.1 - 0.7%，而“Phrygian帽”畸形在4%的患者中可见。文献中未报道过这两种情况合并的其他病例。本文展示了超声和CT检查结果，并讨论了这种畸形的相关方面。还强调了异位胆囊的临床意义，因为它可能改变胆道疾病的临床表现，并在手术过程中带来技术问题。
