Cystadenoma of the Seminal Vesicle

Cystadenoma of the seminal vesicle: US and CT findings

“…Primary seminal vesicle cystadenoma is an extremely rare benign tumor originating from the embryological residues of the Mullerian ducts [6,7].…”

“…Raghuveer and coworkers [9] reviewed eight cases of seminal vesicle cystadenoma and reported one case that was studied with ultrasonography (US). A cystadenoma studied with urography, cystoscopy, and computed tomography (CT), but not US, was reported in 1986 by Bullock [6]. This report describes a patient with cystadenoma of the seminal vesicle who was studied with US and CT.…”

“…The lesions are usually carcinoma, but sarcomas have been reported [1][2][3][4][5]. Benign primary tumors (cystadenomas, mesenchymaltumors) are most uncommon [6][7][8]. Raghuveer and coworkers [9] reviewed eight cases of seminal vesicle cystadenoma and reported one case that was studied with ultrasonography (US).…”

Advanced Concepts in TRISO Fuel

“…87 The idea is to add a layer that traps palladium by chemical reaction inside the SiC layer of the TRISO coating. 89 Figure 12 shows ceramographs of three types of advanced coatings, together with that of the TRISO coating for comparison. The SiC þ PyC layer is composed of SiC with free carbon.…”

“…The SiC þ PyC layer is composed of SiC with free carbon. As the SiC þ PyC layer has a better capability of fission product retention, 89 the thickness of the IPyC layer can be reduced; the IPyC layer should act as a seal to prevent the chemical reaction of the fuel kernel with coating gases during the coating process. 89 Figure 12 shows ceramographs of three types of advanced coatings, together with that of the TRISO coating for comparison.…”
