 A 57-year-old man visited our hospital for further examination concerning autoimmune pancreatitis, and a calcified mass lesion was detected in the ileo-cecal region on abdominal CT scan. Barium enema showed an elevated lesion with smooth surface and about 2 cm in size in the cecum. Colonoscopic study revealed a submucosal tumor-like lesion with a depressed area filled with fecal crusters. Endoscopic ultrasonography displayed a strong acoustic shadow at the lesion, so we diagnosed it as an appendiceal calculus. Laparoscopy-assisted cecectomy was perfomed, and revealed a stone about 3 cm in diameter in the lumen of the appendix rolling about to the cecum. Appendiceal calculus with submucosal tumor-like appearance is very rare, but we must take it into consideration in differentiation from elevated lesions of the cecum.
