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。

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.
