Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。

Results: the 2-d sonography performances of breast cystosarcoma phyllodes larger round or phyllodes tumor with clear border, with or without capsule, as it is of low internal echo, uneven, solution of irregular dark, rare calcification, the rear echo enhanced.

结果：乳腺叶状囊肉瘤的二维声像图表现为乳腺体积较大的圆形或分叶状肿物，边界多清晰，有或无包膜，内部为实性低回声，不均匀；出现不规则液性暗区，少见钙化，后方回声增强。

CT images of the 6 UAs showed homogenous and low density in comparison with muscles. Of the 6 UAs, 2 (33%) were lobulate, 4 (67%) were regularly round or oval; 1 (17%) had bone septa, 2 (33%) had root resorption of the neighboring teeth, 3 (50%) had cortical perforation. All UAs showed well-circumscribed margins without soft tissue masses. Three UAs were examined by enhanced studies and showed mild to moderate enhancement of the wall. Of the 5 MAs, 3 (60%) showed low to intermediate density as compared with muscles, 2 (40%) showed homogenous and intermediate density; 3 (60%) had bone septa; 3 (60%) showed root resorption or destruction of the neighboring teeth. All 5 MAs were lobulate with cortical perforation, soft tissue masses, and ill-defined margins. All 3 MA5 examined by enhanced studies showed strong enhancement. CONCLUSIONS: SMAs are usually seen in middle-aged patients.

UA病变平扫时与肌肉相比内部都呈均匀低密度，其中4例(67%)呈较规整的圆形或椭圆形，2例(33%)呈分叶状，3例(50%)局部骨皮质有缺损，但未见软组织肿块形成，l例(17%)见不全骨性分隔，2例(33%)邻近牙根有吸收，行增强扫描的3例囊壁均呈轻中度的强化。5例MA的病灶都呈分叶状，且骨皮质均被穿破并有软组织肿块形成，边界不清，其中3例(60%)平扫时与肌肉相比呈等低混杂密度，2例(40%)呈较均匀等密度，3例(60%)可见不全的骨性分隔，3例(60%)见牙根的吸收或破坏，行增强扫描的3例都呈明显强化。

Results Among the 8 cases,the center of lesion located in ethmoid sinus was in 3 cases,sphenoid sinus in 3 cases,frontal sinus in 2 cases.4 of 5 primary cases revealed expansible masses,1 case with irregular and lobulated shape;all 3 recurre...

结果8例中病变中心位于筛窦3例，蝶窦3例，额窦2例；5例原发病例中4例病变呈膨胀性生长，1例形态不规则呈分叶状；3例术后复发病变的形态均不规则并呈分叶状；所有病变边界均清晰，伴周围结构不同程度受压。

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。

Results: The main manifestations of imaging in PCCCL appeared as peripheral nodules or masses (6/7) in the right lung. Tiny nodules with coarse spiculate margin, lack of pleural indentation and vacuole sign. When masses of turmor grew larger, smooth margins were found in them. spinous process and cavity were seldom seen. Central mass of left lung superior lobe (n=1), lesion was lobulated, and with smooth margin, which seem others central carcinoma of the lung.

结果：PCCCL影像学上主要表现为右肺周围性肿块或结节(6/7)，结节边缘可见毛刺征，无胸膜凹陷征、空泡征；肿块较大时，边缘光滑，无棘状突起、空洞等征象，1例左肺上叶中心性分叶状肿块，边缘光滑，酷似其它类型肺癌。

Results Angiography showed that the bladder-like filling defect Botryodes7 cases, bladder trigone large lobulated filling defect in 1 cases of video, 5 cases of bladder wall. Four cases of bladder CT examination showed typical grape cluster-shaped cavity below the abdominal wall muscles and soft tissue density mass, partial bladder wall thickening, enhanced scan showed lesions with mild to moderate strengthening.

结果 造影显示膀胱内葡萄簇状充盈缺损7例，膀胱三角区大的分叶状充盈缺损影1例，5例膀胱壁毛糙。4例CT检查均显示膀胱腔内典型葡萄簇状低于腹壁肌肉密度软组织肿块，局部膀胱壁增厚，增强扫描病灶呈轻中度强化。

Results All patients accepted operation treatment,postoperation 5-year survival rate is 100%,recurrence rate of phyllodes tumors is 14.28%,recurrence rate of breast adenoma fibrosum is 2.50%,misdiagnosis rate of phyllodes tumors is 37.5%.

结果 所有患者均经手术治疗，术后5年生存率100%，乳腺叶状肿瘤术后复发率14.28%，纤维腺瘤术后复发率2.50%，分叶状肿瘤的误诊率37.5%。
