病灶

Objective To explore the significance of lung biopsy by CT-guided percutaneous paracentesis in the diagnosis of space-occupying lesions of the lung.

目的 探讨CT引导经皮肺穿刺活检对肺内病灶的诊断价值。

Additionally, right paracentral white matter hyperdensities are present.

另外，右侧旁中央白质也见高信号病灶（前2张图片）。

Cranial MRI showed round foci of signal change of different sizes in the subcortical white matter of the cerebral hemisphere, in the left paramedian portion of the pons and near the fourth ventricle.

脑部MRI见大脑半球皮质下白质的不同部位、左侧脑桥旁正中结构靠近第四脑室处散在许多圆形异常信号病灶。

Sensory impairment and urinary dysfunction also had developed, and paraparesis persisted after the hypokalemia was corrected during hospitalization. An optokinetic nystagmus test showed bilateral sick waves and at the same time a cerebrospinal fluid analysis was normal. A blood examination disclosed borderline anti-nuclear antibodies and an elevated serum IgG level. Her cervical spinal cord showed mild swelling and contrast-enhancement when examined by magnetic resonance imaging. Neither a brain stem nor an optic nerve's lesion was found. Based on the above, acute transverse myelitis was diagnosed. All the symptoms present in the patient relieved gradually after 5-days of pulsed intravenous methylprednisolone therapy.

一50岁女性，因为眩晕、前额头痛、视力模糊、恶心、呕吐及两侧下肢无力而求诊，於低血钾矫正后，两侧下肢无力依然持续，并发生胸部以下感觉缺损及排尿困难等现象，视运动性眼振检查显示两侧波形障碍，脑脊液检查正常，血液学检查显示抗核酸抗体及血清IgG指数偏高，显影剂增强磁振造影显示颈段脊髓肿大且略为显影，并无脑干或视神经的病灶，诊断为急性横断性脊髓炎，给予静脉注射类固醇后症状逐渐缓解。

METHODS: Five patients with histologically confirmed, surgically unresectable metastatic malignant tumors (2 nasopharyngeal carcinomas, 1 pulmonary carcinoma, 1 parosteal sarcoma and 1 bladder carcinoma) that had definitely failed to the conventional chemotherapy an...

放化疗失败或拒绝放化疗并有转移病灶的5例肿瘤患者(2例鼻咽癌，1例肺癌，1例骨旁质肉瘤和1例膀胱癌)，以H101(5×1011～15×1011VP)瘤内注射联合60min42℃局部热疗进行治疗。

Pedunculated,two were in close proximity to vessels. Conclusion Multiphasic CT has moderate sensitivity in the

数肿瘤在增强早期显示明显，肿瘤邻近血管、蒂状突出及非高密度病灶是造成假阴性的潜在因素。

Multiphasic CT has moderate sensitivity in the detection of PETs. Most tumors are more conspicuous on the earlier phases of enhancement. Potential sources of false-negative results include tumors adjacent to vessels, pedunculated morphology, and nonhyperattenuating lesions.

薄层螺旋CT多期扫描对PET的检出敏感性高，多数肿瘤在增强早期显示明显，肿瘤邻近血管、蒂状突出及非高密度病灶是造成假阴性的潜在因素。

Therefore, whenever patients present with severe, recurrent blisters on their palms and soles, especially in elderly patients present with severe, recurrent blisters on their palms and soles, especially in elderly patients with hemorrhagic lesions, dyshidrosiform pemphigoid should be considered.

因此，当病患在手掌及脚底出现严重、常常复发的水泡，特别是在老年人而且病灶主要是以出血性的形式来表现者，异汗样类天疱疮这个疾病应列入考虑。

CT postprocessing technique can display the abnormity of tracheobronchus, MPR can display ideally the narrowing, cutoff, wall thickness of airway, and peribronchial changes;②Peripheral airway disease.

MPR能准确显示病灶与支气管的关系，CTVB可以显示亚段支气管的狭窄、闭塞，但图像模糊，而VR、MinP对其显示不良。

Eighteen (72%) chronic cases showed a pattern resembling usual interstitial pneumonia, but, in most cases, with more peribronchiolar fibrosis than one would expect in UIP.

慢性患者中有18例（72%）的组织结构类似寻常型间质性肺炎，但与UIP不同的是，绝大多数病例细支气管周纤维化病灶不只一处。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
