A 29-year-old multigravida woman presented for her second prenatal ultrasound evaluation at 30 weeks of gestation. The study showed a female fetus, bilateral duplicated systems with severe hydronephrosis in the upper pole moieties and a massively distended bladder. Initial interpretation suggested ectopic/obstructing bilateral ureteroceles. To evaluate these findings further, a prenatal magnetic resonance imaging scan was obtained, documenting the absence of ureteroceles. The presumptive diagnosis of megacystis microcolon intestinal hypoperistalsis syndrome was made. After birth, contrast enema confirmed the presence of microcolon. This appears to be the first reported case of megacystis microcolon intestinal hypoperistalsis syndrome with bilateral duplex systems evaluated with prenatal magnetic resonance imaging.
一名29岁的经产妇在妊娠30周时前来进行第二次产前超声评估。检查显示为女性胎儿，双侧重复系统，上极部分严重肾积水，膀胱极度扩张。初步诊断提示为异位/梗阻性双侧输尿管囊肿。为进一步评估这些发现，进行了产前磁共振成像扫描，结果显示不存在输尿管囊肿。遂作出巨膀胱小结肠肠蠕动不良综合征的推测性诊断。出生后，结肠造影证实存在小结肠。这似乎是首例通过产前磁共振成像评估的伴有双侧重复系统的巨膀胱小结肠肠蠕动不良综合征病例。
