■肝脏淋巴上皮瘤样癌是一种罕见的肝脏原发性恶性肿瘤。淋巴上皮瘤样胆管癌的鉴定非常有限,因为目前很少有此类病例的报道。尽管以前的研究报道了淋巴上皮瘤样胆管癌的病理特征,很少有研究揭示了临床特征,成像特性,以及临床过程和结果。本研究从超声造影、磁共振成像,和病理特征,旨在提高对这种罕见亚型疾病的全面认识。
■一名43岁的女性,有超过20年的乙型肝炎病史,在她的肝脏右叶发现病变。经过多学科小组(MDT)的讨论,根据超声造影和MRI检查不能排除恶性肿瘤。因此,我们决定为病人做手术。术后病理证实为淋巴上皮瘤样肝内胆管癌。经过3个月的随访,患者仍然存活,未观察到复发.
■本文的目的是描述一例罕见的淋巴上皮瘤样肝内胆管癌,并分析其超声造影和MRI造影特征,这将有助于医生诊断这种疾病。从CEUS的角度来看,动脉期病变周围的楔形高度增强区域似乎是炎性的,但根据极快的洗脱,看起来是恶性的。病变在T1WI上显示低信号,T2WI和DWI上的高信号,病变后方可见异常灌注阴影。特别是,这种亚型的胆管癌预后良好,临床医生应提高对疾病的认识,争取早期诊断和治疗。
UNASSIGNED: Lymphoepithelioma-like carcinoma of the liver is a rare primary malignancy of the liver. The identification of lymphoepithelioma-like cholangiocarcinoma is very limited as there are currently very few
reports of such cases. Although previous studies have reported the lymphoepithelioma-like cholangiocarcinoma pathologic features, few studies have revealed the clinic features, imaging characteristics, and clinical course and outcomes. This study was analyzed from multiple aspects such as contrast-enhanced ultrasound, magnetic resonance imaging, and pathological characteristics, aiming to improve the comprehensive understanding of this rare subtype of disease.
UNASSIGNED: A 43-year-old female with a history of hepatitis B for over 20 years presented with a lesion found in the right lobe of her liver. After discussion by a multidisciplinary team (MDT), malignant tumors cannot be excluded based on contrast-enhanced ultrasound and MRI. Thus, we decided to perform surgery for the patient. Postoperative pathology confirmed lymphoepithelioma-like intrahepatic cholangiocarcinoma. After 3 months of follow-up, the patient was still alive and no recurrence was observed.
UNASSIGNED: The purpose of this article is to describe a rare
case of lymphoepithelioma-like intrahepatic cholangiocarcinoma and analyze its contrast-enhanced ultrasound and contrast-enhanced MRI features, which will be helpful for physicians in diagnosing this disease. From the perspective of CEUS, the wedge-shaped highly enhanced area around the lesion in the arterial phase appears to be inflammatory but looks malignant based on the extremely fast washout. The lesion showed a low signal on T1WI, a high signal on T2WI and DWI, and an abnormal perfusion shadow can be seen behind the lesion. In particular, this subtype of cholangiocarcinoma has a good prognosis, the clinician should improve the recognition of the disease to strive for early diagnosis and therapy.
