What Does Soft Tissue Stranding In The Nasopharynx Mean On A CT Scan?

Had some problems with sinus disease, polyps and retained adenoids in adulthood. My ct sinus commented that there is no post choanal extension of poloptosis, although soft tissue stranding is seen in the nasopharynx. The report conclusion said there was no focal or invasive nasopharynx mass. But what does this soft tissue stranding mean? Bit concerned
