良性肿瘤

Materials and Methods: 41 cases of fibrous tumors surgically and pathologically proven (fibroma 5 cases and fibrosarcoma 3 cases, neurofibroma 7 cases, malignant neurofibroma 1 case, angiofibroma 20 cases and ossifying fibrom 6 cases) were studied with retrospective analysis.

CT扫描采用轴位，层厚及间隔 5mm ，部分病例用静脉团注增强后扫描，测量增强前后肿瘤的平均CT值。结果：4种良性肿瘤的不同病理改变决定了各自不同的CT特征，它们在好发部位、病变大小、形态、钙化、增强等均有不同。

摘要硬脊膜外血管性脂肪瘤是一种少见的良性肿瘤，组织学上包含了不同比例的血管和脂肪组织。

In 14 patients with angiogenic tumors of the soft tissue ( 13 benign tumors and 1 malignant tumor) were analyzed. Results Benign hemangiomas included cavernous (n=7), intramuscular (n=2), mixed (n=1), racemosum (n=1), glomus (n=1) and angiomatosis (n=1). The vascular component within the tumor displayed iso-intensity on T1WI relative to the skeletal muscle, and hyper-intensity on T2WI. One case of hemangiopericytoma showed slightly low signal on T1WI and slightly high signal on T2WI.

结果 13例良性肿瘤中，海绵状血管瘤7例，肌肉内血管瘤2例，混合型血管瘤、蔓状血管瘤、血管球瘤、血管瘤病各1例，瘤血管成分在T1WI上呈等信号，T2WI上呈高信号，肿瘤有不等量的纤维组织和脂肪组织；血管外皮细胞瘤1例，T1WI上呈略低信号，T2WI上呈略高信号。

Pleomorphic adenoma is the most common gland tumor of parotid origin, accounting for 60 to 70%. This kind of tumor usually presents as a slow-growing painless mass anteroinferior to the ear. The diagnosis is based on physical examination, image studying and even fine needle aspiration biopsy. The optimal method of treatment of such tumors is local excision or paroidectomy in which the entire capsule is totally dissected off but the facial nerve is spared. Diagnosis and treatment planning are focused on preventing tumor recurrence and consequent malignant transformation.

腮腺之多形性腺瘤乃是唾液腺最常见的肿瘤，约占所有唾液腺良性肿瘤的百分之六十至七十，这类的肿瘤在临床上的表现常是耳下缓慢增生的无痛性肿块，临床上诊断的依据必须配合临床检查、电脑断层扫描、磁振造影及细针抽取切片的病理检查方可得知，其治疗方式主要是对肿瘤进行局部切除手术或腮腺的切除手术，手术中颜面神经需小心保留，但须将肿瘤的外膜部分切除乾净，诊断及治疗计画著重在预防肿瘤复发及肿瘤产生恶性转变。

Results: Thirty-two cases belong to benign lesions, 12 cases of them are hone island, 9 cases are fibrous dysplasia, 7 cases are chondrogenous tumor, 4 cases are infective lesions.

结果：32例为良性病变，其中12例为骨岛，9例为骨纤维异常增殖症，7例为软骨类良性肿瘤，4例为骨感染性病变（2例为结核，2例为非特异性感染）。
