Newborn with a distended abdomen

AXR of complicated meconium ileus / meconium peritonitis
AXR shows displacement of much of the bowel to the left lower quadrant of the abdomen. Faint cresenteric calcifications are seen arcing upwards and downwards on the right side of the abdomen while an oval-shaped calcified object is seen on the left side of the abdomen at the level of the L1 and L2 vertebral bodies. Nodular appearing calcifications are scattered throughout the abdomen.

The diagnosis was complicated meconium ileus. A large meconium pseudocyst was encountered in the operating room.
