Abstract
A 62-year-old woman visited our hospital because of a righ lower abdominal pain and redness of skin around an operation scar. She had recieved an appendectomy 52 years previously. An abdominal X-ray and CT scan revealed a high density mass, similar to a fecal stone in the right lower abdomen. We suspected acute appendicitis with a fecal stone but thought that her appendix had been resected. Antibiotics were administrated, and conservative clinical treatment and observation were performed. The next day, her symptoms worsened and an operation was performed. An appendix remnant showing a phlegmonous change was adhered to the abdominal wall. An appendectomy was performed.
In patients presenting with a right lower abdominal pain, acute appendicitis may be possible even in cases when appendectomy has already been performed. Stump appendicitis is very rare. Ultrasonography is considered to be useful for the diagnosis of acute appendicitis, but a CT scan was more useful in the present case.
