The pathophysiology of acute appendicitis usually involves appendiceal obstruction with continued mucinous fluid secretion and bacterial proliferation within the lumen of the appendix [23]. As such, a fluid- or mucus-filled appendix is recognized as a sign of acute appendicitis at CT [24].

What does it mean if your appendix is fluid filled?

Blockage occurs when the inflammation surrounding the appendix compresses the intestine, and this prevents the intestinal contents from passing. If the intestine above the blockage begins to fill with liquid and gas, the abdomen distends, and greater nausea and vomiting may occur.

Can Appendicolith cause pain?

Appendicolith may cause intermittent abdominal pain. It may mimic stone disease of the genitourinary tract. Sometimes it can be difficult to differentiate acute appendicitis from urolithiasis. Both of these pathologies may cause leukocytosis and hematuria.
