Hello, my questions are regarding my no 2 year old son, Lucas. He was born with congenital lobar emphysema of the upper left lobe. Later, it was found that he had a ccam in the lower left lobe. When he was 9 months old he went through surgery. The ccam was removed completely from the lower left lobe. However, the surgeon stated that the upper left lobe had begun to repair itself, therefore, a good portion of the upper left lobe was removed. But, a small portion of the lung containing the cle was not removed. Is it possible that either condition could come back or grow larger? What symptoms would i need to look out for? Should i be concerned if he has had serious problems with going to sleep for five weeks now? Please help
