Mucocoele of the appendiceal stump

Case contributed by Dr Chris O'Donnell


Appendicectomy 6 weeks ago, now increasing RIF pain

Patient Data:

Age: 45
Gender: Male
Race: Caucasian
Modality: CT
Fluid filled distension of the appendiceal stump with a line of surgical staples at the tip of the stump.  Minimal surrounding inflammatory change.

Case Discussion:

The appendiceal stump is usually buried or inverted into the caecum at surgery to prevent complications including leak, "stumpitis" and mucocoele.  In this case a line of surgical staples has been used acroos the proximal appendix without inversion leaving a small segment of stump allowing a mucocoele to develop.
