患者男,63岁,1年前右侧腹股沟斜疝修补术后复查B超,发现膀胱前上壁占位(具体不详),无自觉症状,近来稍感尿频。实验室检查:尿潜血阴性,LYM%12.2%(20%~50%)。影像学检查:CT平扫示膀胱前上壁等密度肿块,以宽基底与膀胱壁相接,内密度均匀,CT值约49 HU(图1A),增强扫描中度均匀强化,动脉期及静脉期CT值分别约68、86 HU(图1B、C),周围脂肪间隙清晰,可见左侧髂内动脉分支供血。MR示T_2WI呈稍高信号,抑脂序列上呈等信号,与肌肉信号相仿(图2A),T_1WI抑脂序列上呈等/稍高信号(图
Male, 63 years old, a year ago, the right inguinal hernia repair postoperative B-ultrasound, found that the anterior bladder wall occupancy (specific unknown), no symptoms, the recent slight urination. Laboratory tests: urinary occult blood negative, LYM% 12.2% (20% to 50%). Imaging examination: CT scan shows the anterior bladder wall of the same density mass, with a wide basement and the bladder wall connected, uniform density, CT value of about 49 HU (Figure 1A), enhanced scanning enhanced moderate homogenization, arterial phase and vein Period CT values were about 68,86 HU (Figure 1B, C), the surrounding fat clearance is clear, visible left internal iliac arteries branch of the blood supply. MR showed T_2WI showed a slightly higher signal, fat suppression sequence was equal signal, similar to the muscle signal (Figure 2A), T_1WI suppression sequence was the same / slightly higher signal (Figure
