What causes pleural thickening with patchy opacities in the lung?
Patient: My chest xray says: left plueral thickening with patchy opacities of the left upper lung zone.The left hilum is elavated with comparative volume loss of the left lung. The pulmonary vessel on the left shore a hanging down appearance. Foci of calcilification on The right upper zone. Heart size is normal. Doctor: Thanks for your question on HCM. In my opinion you should nit worry much about this report.It is old lesion and must be due to old lesion.You may have old TB and due to this fibrosis occured and long standing fibrosis causes pleural thickening,  fibrosis and calcification and volume loss.So you are having left lung malfunctioning. So better to take pulmonary vaccines like pneumococcal and h.influenzae for prevention of future infection.Better to start pulmonary rehabilitation and chest physiotherapy.
