肝脏上皮样血管内皮细胞瘤超声表现及文献复习

目的:分析肝脏上皮样血管内皮细胞瘤(hepatic epithelioid hemangioendothelioma,HEHE)的超声声像图特征,提高术前超声对HEHE的诊断准确度。方法:对9例病理学检查确诊为HEHE的患者的常规超声及超声造影(contrastenhanced ultrasound,CEUS)表现进行回顾性分析,总结HEHE声像图特征并复习相关文献。结果:9例HEHE患者肿物均为多发占位性病变,位于肝被膜下(部分外凸)或紧邻肝内血管(呈“棒棒糖样”),所有肿物形态尚规则,内部回声不均匀;1例为高回声伴声晕,其余为低回声;2例边界不清,7例边界清。CEUS动脉期环状高增强,门脉期及延迟期为低增强伴中心局部持续不增强,增强模式表现为“快进快出”特点。结论:HEHE的术前超声诊断比较困难,临床工作中遇到肝肿瘤分布在肝包膜下或紧邻肝内血管(呈“棒棒糖样”),CEUS后出现病灶环周增强,中央不增强的“快进快出”的乏血供特点,应考虑到HEHE。

Increased FDG uptake in pulmonary epitheloid hemangioendothelioma

A 40 year-old female was examined for complaints of left arm pain and restriction of movement in the left upper extremity for 3 months. Chest X-ray showed a mass in the left upper lung and the patient was evaluated with computed tomography that confirmed the significant mass in the left paratracheal region and also showed small nodules in both of the lungs. A whole-body FDG-PET scan was performed for the suspicion of malignancy. FDG-PET indicated high FDG accumulation in the lung lesions mainly in the left paratracheal region. FDG-PET findings were highly suspicious of malignancy so the patient had thoracoscopic biopsy of the lesion. The histological findings and immunohistochemistry tests were consistent with pulmonary epitheloid hemangioendothelioma (PEH). Epitheloid hemangioendothelioma (EH) is a systemic name that represents a rare type of malignant tumor of vascular endothelial origin, which can arise in bone, liver, soft-tissue, or lung. PEH is currently known as the lung form of EH. Consequently, our patient had resection of the left paratracheal mass. This report presents a rare case of histologically confirmed PEH, which showed increased FDG accumulation on FDG-PET study. PEH should be added to the other causes of increased FDG uptake.

肝上皮样血管内皮细胞瘤18F-FDG PET/CT显像一例

笔者介绍了1例肝上皮样血管内皮细胞瘤18F-FDG PET/CT显像的病例。从临床症状、实验室检查、病理学检查及影像学等方面分析该病的特点。并通过文献复习了解肝上皮样血管内皮细胞瘤的特点。该病发病率极低,早期症状不明显,不易被发现,且临床表现缺乏特异性,难以与常见肝脏肿瘤相鉴别,在临床上易造成误诊。且该病预后欠佳,目前认为最有效的治疗方法是肝移植或根治性手术切除。     

Atypical imaging findings of infantile hemangioendothelioma: a case report

Infantile hemangioendothelioma is the third most common hepatic tumor in children, and the most common benign vascular tumor of the liver in infancy. On computed tomography (CT) and magnetic resonance imaging (MRI), typical enhancement patterns similar to those seen in adult hemangiomas may help establish the diagnosis. However, atypical enhancement patterns may also occur. In this paper, we report a rare form of solitary infantile hemangioendothelioma that showed a rim-like calcification and rim-like enhancement on CT and MRI.     

Infantile hemangioendothelioma. A case report

The case of a 3-month-old boy with a hepatic infantile hemangioendothelioma is reported. There was no previous history of disease and no symptoms, only an incidentally found abdominal mass. The case is presented as an example of establishing the diagnosis, deciding upon the treatment, and performing the follow-up using only non-invasive imaging techniques.     

Exophytic hepatic hemangioma: a case report

Hepatic hemangiomas may rarely arise outside the extra-hepatic capsule. It appears as a pedunculated mass. We report the case of a 58-year-old female presenting with abdominal chronic pain. Incidental diagnosis of a pedunculated hepatic hemangioma was suggested by ultrasonography confirmed by typical imaging features on computed tomography. Dynamic contrast- enhanced computed tomography and MR scan are relevant to approach the diagnosis of hemangioma, showing its origin from the liver edge and typical radiological features Surgical removal of the mass was performed to prevent volvulus along the pedicle. Pathological analysis confirmed the diagnosis of pedunculated benign hepatic hemangioma.
