Abstract

A meconium pseudocyst is rare and may result in the death of the neonate. Meconium pseudocysts should be distinguished from the cystic-type meconium peritonitis because of their differences in the treatment strategy. Various studies have reported the radiographic and sonographic findings of a meconium peritonitis. However, computed tomography (CT) findings of meconium pseudocyst have been rarely reported yet. In this report we present the CT findings of a patient with a meconium pseudocyst. Such CT findings may help in the proper diagnosis and to distinguish the cystic-type meconium peritonitis from the meconium pseudocyst.

Figure

  • Fig. 1 Immediately after birth, the simple radiograph shows a soft tissue density mass in the mid-abdomen and egg-shell calcifications (arrows).

  • Fig. 2 Abdominal ultrasonography shows a well defined complicated cystic mass with echogenic walls separate from bowel.

  • Fig. 3 A newborn with distended abdomen. A. The non-enhanced axial CT scan reveals a cystic mass with diffuse wall calcification and adjacent mesenteric calcifications. B, C. The contrast-enhanced axial (B) and sagittal CT (C) scans show a nonenhanced cystic mass with wall calcification and communication (arrows) between the cyst and adjacent dilated bowel.
