Choledochal cysts (CDC), are rare congenital dilations involving the extra hepatic biliary apparatus with or without dilation of the intrahepatic bile ducts. They are conventionally classified into five types. A new type, type VI, causing dilation of the cystic duct between the neck of the gall bladder and the common hepatic duct (CHD) has been described in medical literature which is the rarest of all these subtypes. They are commonly observed in middle aged females and are mostly symptomatic. Most of these cysts need magnetic resonance cholangiopancreatography (MRCP) for accurate diagnosis. Treatment options for these lesions are not well defined but range from simple cholecystectomy to complete excision of the entire bile duct and biliary reconstruction, as there is a concern of malignant transformation in these cysts. Hence, these rare cysts, though rare, must be borne in mind when dealing with suspicious cystic lesions in the biliary tract. Here, we present an interesting case of such a rare cyst and its management in a middle aged woman.
胆管囊肿（CDC）是一种罕见的先天性扩张疾病，累及肝外胆道系统，肝内胆管可扩张也可不扩张。传统上，它们被分为五种类型。医学文献中描述了一种新的类型，即VI型，它导致胆囊颈部与肝总管（CHD）之间的胆囊管扩张，这是所有这些亚型中最罕见的。它们常见于中年女性，且大多有症状。这些囊肿大多需要磁共振胰胆管造影（MRCP）来进行准确诊断。这些病变的治疗方案尚未明确界定，但范围从单纯胆囊切除术到整个胆管的完全切除及胆道重建，因为人们担心这些囊肿会发生恶性转化。因此，在处理胆道可疑囊性病变时，必须牢记这些罕见的囊肿，尽管它们很罕见。在此，我们呈现了一位中年女性中这种罕见囊肿的有趣病例及其治疗情况。
