Abstract
A 69-year-old woman underwent total colonoscopy in a health checkup at a local clinic. Colonoscopic study revealed a submucocal tumor-like lesion at the appendiceal orifice. She was admitted to our hospital for an elaborate investigation and treatment. Abdominal plain X-ray showed calcification in the right lower abdomen. Abdominal CT scan demonstrated a high density mass in the ileo-cecal region. Thus, we diagnosed the symptom as asymptomatic appendicolithiasis. She underwent laparoscopic appendectomy. As asymptomatic appendicolithiasis is very rare, we report this case with a review of some literature.
