Hi Doctor, I am a 38 year old male. Every year for the past 4 years already, our company requires us again to undergo a chest PA x-ray, for health awareness and safety. I have had a normal chest PA result for the past years, except that i have had a minor/mild dextroscoliosis that was discovered only last 2004, and previous to this i cant remember when was my last xray. Only recently, this year on January, i had the following chest PA xray result: Followup examination since January 25, 2013 shows: There is now a faint nodular density in the right upper long superimposed in the right 4th and 5th posterior ribs (suggest apicolordotic view for further evaluation). The heart is not enlarged. Both costrophrenic sulci and hemidiaphragms are intact. Mild thoracic spine dextroscoliosis is still seen. No other remarkable interval findings. Doctor, am i in trouble with these results? What does this faint nodular density in the right upper lung superimposed in the right 4th and 5th posterior ribs? Please enlighten me. Thank you very much.
