Appendicitis is a worldwide problem with a fascinating epidemiology which deserves researches. In the 1960s, such much needed research was directed to expanding its boundaries. This resulted in promoting its acute “limited” variety. It was in this context that the crypt abscess within it came into prominence. Accordingly, what can follow when these abscesses resolve? It is necessarily the formation of determinable ovoid spaces. Since these can be recognized with biomedical graphics, it is hypothesized that archival films, which abound all over the world, will promote the epidemiologic study of this vestigial organ.

Worldwide problems concern the epidemiology of appendicitis undoubtedly [1,2]. In order to improve on a better knowledge of it, Howie  stressed the importance of including the “limited” form of it in classifications! However, as he put it, “I have disregarded solitary crypt abscesses which do not show invasion of the adjacent stroma by polymorphonuclear leucocytes.”
I am persuaded that such abscesses found in the crypts of Lieberkuhn are an important phenomenon, especially as their pictures must vary from (a) that of emptiness, (b) through scanty necrotic polymorphs, and (c) to crowding with lively polymorphs. Figure 1 illustrates the classic ovoid space which is the seemingly empty dilated crypt.

My impression is that this picture came to my mind because of examining the specimens from the patients of the Igbo ethnic group , in whom the appendix mass was treated and allowed to resolve before the resort to surgery . Moreover, since incidental appendicectomy cases are likely to reveal hidden pathologies [6,7], they are liable to be positively identifiable when involved. In all probability, the more the collections which are made, the more the positive knowledge that will accrue . And this is where archival radiographs can be mustered strong worldwide.
