Appendicitis is the inflammation of the appendix, a small, finger-shaped pouch attached to the large intestine in the lower right abdomen, which is a medical emergency often caused by a blockage leading to infection and swelling, resulting in sudden, severe pain, nausea, and fever, requiring immediate treatment like surgical removal.

On ultrasound, an inflamed appendix typically appears as:
๐นBlind-ending tubular structure in the right lower quadrant
๐นNon-compressible on graded compression
๐นEnlarged outer diameter >6โ7 mm
๐นThickened, hypoechoic wall
๐นLoss of normal wall layering in advanced disease.

Acute appendicitis on ultrasound typically appears as an enlarged, blind-ending appendix that is non-compressible. The outer diameter is increased, the wall is thickened and hypoechoic, and normal wall layers are usually preserved. On color Doppler, mural vascularity is often increased due to active inflammation. The lumen may contain anechoic or hypoechoic fluid.

Gangrenous appendicitis represents a more advanced stage of inflammation. The appendix is markedly enlarged, commonly measuring around 10โ15 mm in diameter, with pronounced wall thickening. Normal wall stratification is lost, giving the wall a more irregular and heterogeneous appearance. Because of ischemia and necrosis, color Doppler typically shows reduced or absent mural blood flow.

Appendicitis with an appendicolith is characterized by a bright echogenic focus within the appendiceal lumen, producing a clear posterior acoustic shadow. The presence of an appendicolith suggests luminal obstruction and is strongly associated with more severe inflammation and a higher risk of complications such as perforation.

Perforated appendicitis with abscess formation is identified by focal discontinuity of the appendiceal wall and poor visualization of a normal appendiceal structure. The appendix may appear collapsed or ill-defined. Surrounding findings include peri-appendiceal fluid collections or a well-formed abscess, inflamed echogenic mesenteric fat, and sometimes free fluid, all of which point toward perforation and advanced disease.
