Multicystic biliary hamartoma (MCBH) is a very rare hepatic benign neoplasm that manifests as a localized cystic-solid mass. Only 17 cases have been described in the literature to date. MCBH diagnosis is currently dependent on imaging and pathology following surgical resection and no precise standards are in place.
This case study involves a middle-aged male patient with a history of drinking but no other liver diseases. A routine ultrasound examination showed a 6.0 × 5.5 cm inhomogeneous echo mass in the right lobe of the liver. The patient experienced no discomfort or other symptoms, and blood tests were normal. Imaging revealed a localized cystic-solid neoplasm in segment 6 of the liver that did not have the features of a malignant tumor. Surgical resection was performed. Based on imaging, macroscopic examination, and histological results, a final diagnosis of MCBH was made.
The imaging and pathological features of MCBH were summarized based on the published case reports to date. As a non-invasive examination, the imaging features will aid in the diagnosis of MCBH. Furthermore, these features, along with tumor size and patient symptoms, will facilitate clinicians in selecting surgical resection or follow-up for individual patients.
多囊性胆管错构瘤（MCBH）是一种非常罕见的肝脏良性肿瘤，表现为局限性囊实性肿块。迄今为止，文献中仅描述了17例。目前，MCBH的诊断依赖于手术切除后的影像学检查和病理学检查，尚无精确的标准。
本病例研究涉及一名中年男性患者，有饮酒史但无其他肝脏疾病。常规超声检查显示肝脏右叶有一个6.0×5.5厘米的不均匀回声肿块。患者无不适或其他症状，血液检查正常。影像学检查显示肝脏第6段有一个局限性囊实性肿瘤，不具有恶性肿瘤的特征。进行了手术切除。根据影像学、大体检查和组织学结果，最终诊断为MCBH。
基于迄今为止已发表的病例报告，总结了MCBH的影像学和病理学特征。作为一种非侵入性检查，影像学特征将有助于MCBH的诊断。此外，这些特征以及肿瘤大小和患者症状，将有助于临床医生为个体患者选择手术切除或随访方案。
