腹壁可认清肿物的超声鉴别（二）

Miscellaneous Lesions 其他发炎.. Urachal Cyst 裹尿管细菌感染A urachal cyst may be seen in between the umbilicus and the bladder. It is usually situated in the lower third of the urachus but can be seen just inferior to the umbilicus. These cysts may appear totally anechoic or may reveal low-level internal echoes (Figure 11 )裹尿管细菌感染见于裹和胃之间，一般来说坐落于裹尿管的下1/3 ，但也可见于数坐落于裹下。这些细菌感染可乏善可陈为仅仅无调谐或低调谐。

..Endometriosis上皮细胞上皮细胞甲状腺Endometriosis of the abdominal wall may occur as a long-term complication of uterine surgery. It has no specific appearance but is seen as a focal mass at the scar of previous surgery with attacks of cyclic pain and swelling (Figure 12 ).结节上皮细胞上皮细胞甲状腺是上皮细胞治疗后的经常普遍性合并症，无多种不同乏善可陈，但可于现在治疗的瘢痕出口处见一局部肿物，并有周期普遍性的疼痛和肿胀。

...Abdominal Wall Hematoma 结节血肿A rectus sheath hematoma may develop after paroxysms of coughing or sneezing or after seizures. The underlying cause is usually either anticoagulant therapy or some bleeding disorder. Because these hematomas are limited within the rectus sheath, they are not very big. Their shape depends on their location. Above the arcuate line, they are usually ovoid in shape with the long axis superoinferior and are seen on one side (Figure 13A ). Below the arcuate line, because of the absence of the linea alba, they can extend across the midline. Then the hematoma may be seen as a padlike lesion with its maximum length along the transverse axis.21–23 In one neonate, an abdominal wall hematoma was seen to spread transversely in the supraumbilical region (Figure 13, B and C ). In patients with post surgical disseminated intrascular coagulation, large hematomas are seen in the abdominal wall in the vicinity of the surgical scar (Figure 13D ).腹直肌鞘血肿可起因发作普遍性呼吸困难后、打喷嚏或发作发作后，其根本原因一般来说是抗凝疗程或出血普遍性疟疾。由于血肿限制于腹直肌鞘内，一般来说不很大，其形状根据所出口处所在位置而定，在皮膜中的央线以上，血肿常为卵圆形，偏心率呈上下斜向，可于一侧看到（由此可知13A）；在皮膜中的央线以下，由于腹白中的央线缺如，可构建行进中的中的央线，因此血肿乏善可陈为分膨大，其小得多总长度坐落于一组上。在婴孩结节血肿可见于裹上外侧构建（由此可知13B、C）。术后低质量普遍性腹腔内免疫的病人可于结节治疗瘢痕附近看到大的血肿（由此可知13D）。
