Isolated Submucosal Lipomatosis of the Appendix: A Rare Incidental Finding on Contrast-Enhanced Computed Tomography
Abstract: Appendiceal lipomatosis is an exceptionally rare benign condition characterised by fatty infiltration of the appendiceal wall. Its isolated submucosal variant- occurring without inflammation, luminal obstruction, or neoplasm- is among the least reported entities in radiological literature and is most often discovered incidentally. We present the case of a 50-year-old male investigated for left flank pain in whom contrast-enhanced computed tomography (CECT) of the abdomen incidentally demonstrated near-complete fat attenuation (-75 to -130 HU) along the entire length of a non-inflamed appendix, with no periappendiceal fat stranding or luminal dilatation, consistent with isolated submucosal lipomatosis of the appendix. Recognition of this entity on CT is important to distinguish it from acute appendicitis and appendiceal neoplasm and thereby avoid unnecessary surgical intervention. This report highlights its characteristic imaging features and differential diagnosis.
