解析

Granulomatous  /,ɡrænju'lɔmətəs/

释    义   adj. 肉芽肿的

例    句   They develop when lipid breakdown products leak into the surrounding tissues from either bacterial enzymes or retained sebaceous secretions and incite a granulomatous inflammatory reaction.其起因是脂肪分解产物由于细菌酶的作用或皮脂腺分泌物的潴留而渗入周围组织,并从而引发了肉芽肿性炎症反应。

 

Prostatitis  英  /,prɒsteɪ'taɪtɪs/  美  /,prɑstə'taɪtɪs/

释    义   n. [泌尿] 前列腺炎,摄护腺炎

例    句   Three main problems can occur in the prostate gland: inflammation or infection, called prostatitis; enlargement, called benign prostatic hyperplasia (BPH); and cancer.前列腺三个主要病症是炎症或感染,统称前列腺炎;增生,称之为良性前列腺肥大;还有癌症。

概述

  肉芽肿性前列腺炎是前列腺炎症的一种特殊的类型,也是一种常见的男性疾病。从病理上看主要表现为局部的炎症,可能是细菌感染引起的炎症,也可能是创伤引起的,比较难以治疗,所以需要根据不同的病因,多方面的考虑问题,给予患者针对性的治疗。   症状   83%的患者有严重的下尿路感染症状,如发热、寒战、尿频、尿道烧灼感、尿痛,偶见血尿、会阴痛、耻骨上不适。直肠指检:肉芽肿性前列腺炎肿块一般发展较快,结节较大,有弹性,不规则,软硬

This patient presented with a well-defined lesion in the peripheral zone that demonstrated hypointense signal on T2-weighted images. The primary consideration was prostate cancer, although an exophytic benign prostatic hyperplasia nodule, an infarct, and granulomatous prostatitis also could be included in the differential diagnosis. This appearance is characteristic of prostate cancer, and the associated contour bulge of the glandular margin suggests the possibility of extraglandular extension. However, the lack of hyperintense signal on diffusion-weighted images and peripheral enhancement with absence of central contrast enhancement would be very atypical. The lesion is distant from the transition zone, and although exophytic benign prostatic hyperplasia nodules occasionally occur in this location, these characteristically demonstrate a well-defined capsule on T2-weighted images and tend to have a heterogeneous appearance on these images as opposed to the homogeneous very low signal intensity of the lesion in this patient. Additionally, if this were an exophytic benign prostatic hyperplasia nodule, internal contrast enhancement would be expected. Although an infarct could have a similar appearance, no potential risk factor for pelvic ischemia, such as a history of prostatic arterial embolization, was provided. Moreover, in the postembolization setting, infarcts have been reported to occur exclusively in the central gland.

译文

该患者在周围区域表现出明确的病变,在T2加权图像上显示出低信号。主要考虑因素是前列腺癌,尽管外生性良性前列腺增生性结节,梗塞和肉芽肿性前列腺炎也可以包括在鉴别诊断中。这种外观是前列腺癌的特征,并且腺缘的相关轮廓隆起提示了腺外扩张的可能性。但是,在弥散加权图像上缺少高强度信号,而在缺乏中央对比度增强的情况下进行外围增强将是非常不典型的。病变远离过渡区,尽管外生性良性前列腺增生性结节偶尔会出现在该位置,但这些特征在T2加权图像上表现出明确的囊膜,并且在这些图像上具有异质的外观,而不是均质的。该患者病变的信号强度非常低。另外,如果这是外生性良性前列腺增生性结节,则可以预期内部对比增强。尽管梗死的外观可能相似,但并未提供盆腔缺血的潜在危险因素,例如前列腺动脉栓塞史。此外,据报道在栓塞后环境中,梗塞仅发生在中央腺体中。
