Objective To investigate the clinicopathologic characteristics and reason of tissue injury caused by klebsiella rhinoscleromatis infection.

目的观察鼻硬结病的组织病理学和临床特点，探讨鼻硬结杆菌对宿主造成组织损伤的机理。

Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure. CT showed that the rhinoscleroma in granulomatous stage was a soft mass which was irregular in shape, with a well-defined margin, inhomogeneous density and bone destruction. MRI showed heterogeneous hyperintensity on T1WI and isointensity on T2WI with an intermediate heterogeneous enhancement.

结果：病变起源于左侧后鼻孔及左侧蝶窦区，累及左侧咽粘膜间隙、左侧颞下窝及邻近骨质；结合本病例及文献复习，肉芽肿期鼻硬结病CT表现为不规则软组织肿块，轮廓清楚，密度不均匀，可见骨质破坏，残存骨质呈硬化改变；MRI表现为T1WI高信号T2WI等信号影，信号不均匀，增强后中度不均匀强化。

Methods: A case of rhinoscleroma involving infratemporal fossa was reported.

报道1例鼻硬结病侵犯颞下窝并文献复习。

Methods Twenty-four cases with non-pituitary lesions in sphenoidal sinus and sellar area were analyzed . Eighteen cases were benign, including 7 sphenoidal sinus cyst, 6 craniopharyngioma, 2 chordoma, 1 nasal polyp extending into the sella,1 neuronoma in sella,and 1 pinealoma.

总结分析24例蝶窦鞍区非垂体源性占位性病变，其中良性18例，包括蝶窦囊肿7例、颅咽管瘤6例、脊索瘤2例，鼻息肉伴鼻硬结杆菌感染侵犯蝶窦鞍区、蝶鞍神经鞘瘤、鞍内异位松果体瘤各1例。

Objective To investigate the CT and MRI findings of rhinoscleroma so as to improve the diagnostic accuracy.

目的探讨鼻硬结病的CT和MRI表现，提高其诊断准确性。

Materials and Methods CT and MRI appearances of 10 cases with rhinoscleroma confirmed by pathology were analyzed retrospectively.

资料与方法回顾性分析10例经病理证实的鼻硬结病的影像学资料。

CT and MRI findings can provide comprehensive accurate information for the diagnosis and treatment of rhinoscleroma.

两者结合能够为鼻硬结病的诊断及治疗提供更全面准确的信息。

A small number of other organelles such as endoplasmic reticulums and lysozymes were squeezed to the side of cells. There were many granular substances on the surface of intracellular bacteria, which were not found on the extracellular KR.

绝大多数鼻硬结杆菌寄宿于Mikulicz细胞的吞噬泡内，数量多达十几条，细菌壁有一层高电子密度的粗、细颗粒，显示胞内菌的特点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
