[Extraperitoneal appendicular calculi (author's transl)].

Two retrocecal and extraperitoneal appendix cases are showed. Atypical clinical signs, slow evolution, perforation and abscess were found. Radiological diagnosis is based by seeing the calculus and the appendix by means of barium enema. When appendix calculus is demonstrated and clinical signs are present, a surgical operation must be order urgently. Profilactic appendicectomy is recommended when no symptoms.
