摘要
We herein report the case of an idiopathic liver cystic mass which aggressively infiltrated the thoracoabdominal wall. A 74-year-old woman who had a huge cystic lesion in her right hepatic lobe was transferred to our hospital for further examinations. Imaging studies revealed a simple liver cyst, and the cytological findings of intracystic fluid were negative. She was followed up periodically by computed tomography （CT） scans. Seven years later, she complained of a prominence and dull pain in her right thoraco-abdominal region. CT revealed an enlargement of the cystic lesion and infiltration into the intercostal subcutaneous tissue. We suspected the development of a malignancy inside the liver cyst such as cystadenocarcinoma, and she therefore underwent surgery. A tumor extirpation was performed, including the chest wall, from the 7th to the 10th rib, as well as a right hepatic Iobectomy. Pathologically, the lesion consisted of severe inflammatory change with epithelioid cell granuloma and bone destruction without any malignant neoplasm. No specific pathogens were evident based on further histological and molecular examinations. Therefore the lesion was diagnosed to be a destructive granuloma associated with a long-standing hepatic cyst. Since undergoing surgery, the patient has been doing well without any signs of recurrence.
我们此处报导一个自发的肝的案例好攻击地渗入了 thoraco 腹的墙的膀胱的质量。在她的恰好肝的脑叶有巨大的膀胱的损害的一个 74 岁的女人为进一步的考试被转移到我们的医院。成像研究揭示了简单的肝包囊，并且 intracystic 液体的 cytological 调查结果是否定的。她被跟随在上面周期性地由计算断层摄影术(CT ) 扫描。七年以后，她在她的恰好 thoraco 腹的区域抱怨了突起和钝痛。CT 揭示了膀胱的损害和渗入的增大进脊间的皮下组织。我们在象包囊腺癌那样的肝包囊内怀疑了发展恶意，并且她因此经历了外科。肿瘤根除被执行，包括胸壁，从第 7 到第 10 肋骨，以及恰好肝的叶切除术。病理地，没有任何恶意的瘤，损害与上皮状的房间肉芽肿和骨头破坏由严重煽动性的变化组成了。没有特定的病原体基于进一步组织学、分子的考试是明显的。因此，损害被诊断是与长期的肝的包囊联系的破坏肉芽肿。自从经历外科，没有复发的任何符号，病人一直在做很好。
