Miscellaneous Lesions 其他病变.. Urachal Cyst 裹尿管溃疡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 )裹尿管溃疡见于裹和膀胱之间，一般来说坐落于裹尿管的下1/3 ，但也可见于仅坐落于裹下。这些溃疡可展现出为全然无水声或低水声。

..Endometriosis睾丸粘液异位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 ).面有睾丸粘液异位是睾丸康复的长期合并症，无特殊展现出，但可于以前开刀的瘢痕不远处见一全局肿物，并有周期官能的头痛和腹痛。

...Abdominal Wall Hematoma 面有血肿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 ).腹直肌鞘血肿可拉开序幕癫痫官能咳嗽后、喷嚏或癫痫癫痫后，其根本原因一般来说是抗凝外科手术或出血官能疾病。由于血肿限制于腹直肌鞘内，一般来说不不小，其形状根据所不远处右边而定，在弓状本站以上，血肿常为卵圆形，长轴呈上下方向，可于右侧见到（示意图13A）；在弓状本站请注意，由于腹白本站缺如，可构建横过之前本站，因此血肿展现出为分叶状，其最大者宽度坐落于中点上。在婴儿面有血肿可见于裹上横向构建（示意图13B、C）。术后致密官能甲状腺内凝血的病患可于面有开刀瘢痕临近见到大的血肿（示意图13D）。
