A case of giant meconium pseudocyst secondary to ileum volvulus perforation is presented. Conventional radiographic features of meconium peritonitis with secondary meconium pseudocyst formation are well described. Our case is unusual in comparison to other cases reported in the literature and needs to be reported because the meconium pseudocyst presented without the typical ultrasound features (calcifications, polyhydramnios and ascites) and was initially identified as an abdominal mass.
We describe the case of a 29-year-old Caucasian woman in her third trimester of pregnancy, in which an abdominal mass was detected in the fetus. The newborn was diagnosed in the early neonatal period with meconium pseudocyst secondary to ileum volvulus perforation.
The prenatal appearance of a meconium pseudocyst can be complemented by other signs of bowel obstruction (if present) such as polyhydramnios and fetal bowel dilatation. This is an original case report of interest to all clinicians in the perinatology and fetal ultrasound field. We consider that the utility of this case is the recognition that a meconium pseudocyst might appear without the typical ultrasound features and should be considered as a differential diagnosis when an echogenic intra-abdominal cyst is seen.
本文报告一例因回肠扭转穿孔继发巨大胎粪假性囊肿的病例。胎粪性腹膜炎伴继发性胎粪假性囊肿形成的传统影像学特征已有详细描述。与文献报道的其他病例相比，我们的病例较为罕见，需要报告，因为该胎粪假性囊肿没有典型的超声特征（钙化、羊水过多和腹水），最初被诊断为腹部肿块。
我们描述了一名处于妊娠晚期的29岁白种女性病例，在胎儿期检测到腹部肿块。新生儿在新生儿早期被诊断为回肠扭转穿孔继发胎粪假性囊肿。
胎粪假性囊肿的产前表现可伴有其他肠梗阻体征（如有），如羊水过多和胎儿肠管扩张。这是一篇围产医学和胎儿超声领域所有临床医生都感兴趣的原创病例报告。我们认为该病例的意义在于认识到胎粪假性囊肿可能不具有典型的超声特征，当在腹腔内发现强回声囊肿时，应将其作为鉴别诊断考虑。
