What is the diagnosis?

摘要

A baby boy was born at at a gestation of 29 weeks 5 days with birth weight 1350 gram to a healthy Chinese couple via normal spontaneous vaginal delivery. He was admitted to our NICU for prematurity. He had normal heart rates and oxygen saturation in room air. For delivering parenteral nutrition, percutaneously inserted central catheter (PICC) was inserted through the right basilic vein. An anteroposterior chest X-ray was performed to confirm the correct location of the PICC tip after insertion (Figure 1).
