However, radiologically, they are all seen as intralumenal shadows and present a potential hazard. Therefore, we, as radiologists, will define a polyp as “any pedunculated newgrowth arising from a mucous surface regardless of its histologic characteristics.” There are two types which are most commonly encountered. They are the adenoma and the pedunculated growth formed by hyperplasia of the mucous membranes. The etiology of polyps, as of newgrowths in general, is speculative. There are a few facts which are associated with the development of these types of newgrowths. Some of the polyps encountered in the large bowel are found concomitantly with inflammatory or ulcerative changes. These are not true newgrowths, but are either glandular hyperplasia or fragments of mucous membrane which have become infiltrated with leukocytes and plasma cells (Saint). Wesson... |
