title: Agenesis of the appendix vermiformis.
abstract: Agenesis of the appendix vermiformis represents a rare condition that accounts in approximately 1 in 100.000 laparotomies performed for suspected acute appendicitis. L.B., female, born at term after a normal pregnancy. Shortly after birth she presented respiratory distress; chest x-ray showed a left diaphragmatic hernia (CDH). At operation was noted the absence of the appendix and of the mesenteriolum as well together with the presence of a mesenterium commune. Other associated anomalies were detected: dextroposition of the heart, hypoplasia cnemis, hexadactylism of right foot, congenital hip displacement and bilateral congenital cataract. Etiopathogenesis of the agenesis of the appendix can be easily understood from an embryological point of view, following the cecal pole development. Diagnosis of this malformation is possible only after an accurate laparotomic or laparoscopic exploration around the ileocecal and retrocecal zone.
