What Does Consolidation Opacity Measuring Up To 13.1 X 8.8 Mean?

My husband has had lung cancer for one and a half years with treatment being relatively successful. The most recent report states that he has a consolidative opacity measuring up to aparoximately 13.1 x 8.8. Does that mean that is the size of the tumor itself OR the size of the scar tissue and tumor?

Hello, I have read your query.
A mass and consolidation are very close differentials, and differences in attenuation, enhancement etc are taken into consideration to differentiate them.
There maybe masses within a consolidation as well, hence they are measured as one large opacity.
They may appear similar on a CT, with many overlapping findings.
The best way to assess the current study to know if its a new or growing lesion, is to compare it to the earlier scans.

Also we need to keep in mind what kind of treatment he's had- eg surgery, Radiotherapy, biopsy etc, as these can also cause changes.
Your doctor may suggest medication and a re-scan sos biopsy.
Hope this is helpful. Wishing you and your husband good health. Take care.
