I am sorry to hear of your problem. What you describe, a nodule, is an abnormal shadow that appears in the substance of a lung, either on Chest X-ray or CT Scan. I cannot tell the size of this nodule from the numbers you have provided but, in general, larger masses with rough, irregular margins that show no calcification within the mass are often described as “indeterminate.” You and your doctors should strive to locate any prior chest X-rays, you may have had, for comparison with the current CT Scan.
The word, Atelectasis, refers to a collapse (loss of volume) of a portion of one’s lung. That can be caused by obstruction to airflow into that portion of lung, by a nodule.
Radiologists can offer an opinion on the nature of a nodule on the basis of its appearance, rate of growth and associated symptoms but, to establish a definite diagnosis, often requires what is called bronchoscopy, direct examination of the nodule inside a bronchial tube with the use of an instrument called a fiberoptic bronchoscope, the exam usually performed by a lung specialist (Pulmonologist).
