Followup Question re CTC/CT Scan

Hi Doctor.  You said that the enlarged lymph nodes in the mesocolon is probably not due to cancer, given that no increase in node size seems to have taken place between the 7 months.  
The concern or the impression from the radiologist was as follows:  Mural thickening, luminal narrowing and hyperemia are in keeping with on going diverticulitis, presence of adenopathy is concerning and biopsy of this segment is advised.  There were no other focal colonic leasions.  
The scan in Dec 2008 also indicated some enlarged lymph nodes.  Couple questions.  Can the enlarged nodes i.e 7-8mm in short axis be due to the progression of diverticular disease.  I understand that inflammatory changes in the sigmoid mesolcolon has been seen on the last couple CT's, which as i understand it is in keeping with the diseases progression as well.  Given there were not other lesions is it possible that the enlarged nodes are due to Lymphoma.  Or because this doesn't seem to have grown much in the last 7 months, not likely.

Hi,
Untreated lymphoma (even low grade ones) would be expected to grow substantially more than 7 mm over a period of several months.
Relax.
