Ultrasonographic findings in diseases of the appendix
S. G. Parulekar
Ultrasonographic findings in patients with diseases of the appendix,
including acute appendicitis, suspected appendiceal abscess, and palpable
right-lower-quadrant abdominal mass, are described. An appendiceal abscess
may manifest as a cystic mass, a mixed solid and cystic mass, or a
hypoechoic solid mass. An appendiceal calculus within an abscess can be
recognized as a hyperechoic structure with acoustic shadowing. On
ultrasonography, acute appendicitis in female patients may mimic
tubo-ovarian disease. Ultrasonographic features of isolated Crohn's disease
of the appendix and mucocele of the appendix are also described.
