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.
