Hello Doctor, My mother is aged 72 and she has been suffering from acute bronchitis for the past 5 years. She has been treated time and again by the Physician. Recently she was again treated for the same and this time her X-ray report is as follows: ALK Calcification , clear lung fields, normal cardia , left basal haziness. Can u plz tell me what does the left basal haziness mean. Is there anything seriously wrong with her lung. Please do let me know. Thanking you in anticipation, Harish Kumar.
