Recent CT showed bilateral dependent atelectasis can you clarify exactly what

Resolved Question:

Recent CT showed "bilateral dependent atelectasis" can you clarify exactly what this means? I am very aware of the seriousness of atelectasis, but I am confused by this terminology. Should I be concerned or seek further studies?

May I know the symptoms you are having? Do you have any diagnosed medical condition?
Customer: replied 5 years ago.
Original studies were to r/o "possible renal mass" on rt. kidney (as reported from bone scan) due to persistent pain in rt. side and back. No mass determined. No evidence of stones. CT report also noted "mild hepatomegaly" (which I am aware is slightly enlarged liver).Recently dx. diabetes. Taking no meds. yet, prefer to try to control with diet. I do have nursing background, so I have just enough medical knowledge to want further clarification re: "dependent bilateral atelectasis" since I know that certain types of atelectasis can be very serious. What are the causes, and what kind of treatment/testing should be done, if any? Thank you for any clarification/assistance you can offer.

I can understand your anxiety.

Atelectasis is the word used to describe collapsed lung {though it does not mean complete collapse}. It seen at bilateral lungs relieves me a bit. When an individual stays in supine position {generally during a CT scan} the portion of lung {dependent} does not inflate completely. This is seen as partial collapse/ haziness or ground glass opacity. This can also happen due to not deep inspiration {pain can be the cause}. Having said this causes like pulmonary edema should be considered. The way out is to rescan the patient in prone position. By doing this the dependent atelectasis vanishes.

Wish you well. God bless
