Abstract
OBJECTIVE
To study the clinical features of neuroendocrine cell hyperplasia of infancy (NEHI) in order to provide a basis for the management of diagnosis, treatment and prognosis of children with NEHI.
METHODS
A retrospective analysis was performed for the clinical data of seven children with NEHI who were diagnosed and treated from January 2014 to March 2016.
RESULTS
Among the seven children with NEHI, there were five boys and two girls. Two children experienced tachypnea since the neonatal period, and five children developed respiratory tract symptoms within 1-6 months after birth. Of the 7 children, 6 had pulmonary crackles, 4 had hypoxemia, and 3 had gastroesophageal reflux. Lung high-resolution CT (HRCT) showed ground-glass opacities in the central region of the lungs in all children, which involved at least two lung lobes. Of the 7 children, 2 had the involvement of more than 4 lobes and 6 had air trapping. All 7 children had an improvement in clinical symptoms after two years of age. One child achieved clinical and CT remission. Four children achieved clinical remission, but still with CT changes.
CONCLUSIONS
NEHI often occurs in infancy, with the major clinical manifestations of persistent tachypnea, pulmonary crackles, and hypoxemia. The children with NEHI often present ground-glass opacities in the central region of the lungs and air trapping on HRCT. There is no specific treatment for this disease and most cases have a good prognosis.
