Choledochal cysts are congenital segmental aneurysmal dilatations of any portion of bile ducts, most commonly of the main portion of the common bile duct. The classification system of choledochal cysts is based on the site of the cyst or dilatation and currently includes 5 major types. The purpose of our study is to describe the imaging findings of a new variant of choledochal cyst.
Six patients (4 children and 2 adults, 4 females and 2 males, 3-67 year old) were evaluated by US, CT, CT-cholangiography, MRI, magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP), because of jaundice, abdominal pain and a palpable mass.
A new type of choledochal cyst was demonstrated in all cases. In this new variant apart from the dilatation of the common hepatic and the common bile duct, dilatation of the central portion of the cystic duct was also observed, giving a bicornal configuration to the cyst.
The imaging findings of a new variant of choledochal cyst with participation of the cystic duct are described. We propose the classification of this type of choledochal cyst as a new subtype of Todani I cyst, namely Todani ID.
胆管囊肿是胆管任何部位的先天性节段性动脉瘤样扩张，最常见于胆总管主干部分。胆管囊肿的分类系统基于囊肿或扩张的部位，目前包括5种主要类型。本研究的目的是描述一种新型胆管囊肿的影像学表现。
对6例患者（4例儿童和2例成人，4例女性和2例男性，年龄3 - 67岁）进行了超声、CT、CT胆管造影、MRI、磁共振胰胆管造影（MRCP）和内镜逆行胰胆管造影（ERCP）检查，这些患者因黄疸、腹痛和可触及肿块而就诊。
所有病例均显示出一种新型胆管囊肿。在这种新变体中，除了肝总管和胆总管扩张外，还观察到胆囊管中部扩张，使囊肿呈双角形。
描述了一种累及胆囊管的新型胆管囊肿的影像学表现。我们建议将这种类型的胆管囊肿分类为托达尼I型囊肿的一个新亚型，即托达尼ID型。
