Infected abdominal aortic aneurysms are uncommon but not rare (1-3% of all abdominal aortic aneurysms). This life-threatening disease can lead to rapid uncontrolled sepsis and/or aortic rupture. We report one case that underlines two notions. Firstly computed tomography is effective to detect early stages of the pathology providing complete depiction of the anatomical abnormalities. Secondly infected aortic aneurysm can be successfully treated by antibiotherapy and in situ replacement with cryopreserved arterial homograft.

Twenty cases of cystic adenomatoid malformation of the lung were observed: 2 had died in utero; the diagnosis was made at birth in 13 infants of which 3 were premature. A Bochdalek's hernia had been diagnosed before birth in 2 cases by echo-tomography. The correct antenatal diagnosis had been made in 2 cases. Two infants had no symptoms, 3 were dyspneic, 8 were in respiratory distress and had to be intubated and ventilated. Two had a prune belly syndrome. Eight infants had a thoracotomy during their first week of life. Pulmonary resections concerning those 13 patients comprised 10 lower lobectomies, 1 of which was associated with a lingulectomy, and 2 upper lobectomies, 1 of which was associated with a middle lobe resection. Five patients were diagnosed and operated upon between 10 months and 8 years of age; 4 had recurrent bronchitis and 1 was diagnosed during the treatment of a gastroenteritis. They had 3 lower and 2 upper lobectomies. Recovery was uneventful in all patients except for 1 who was reoperated upon for intestinal obstruction. Antenatal diagnosis of cystic adenomatoid malformation should become standard. The malformation may be mistaken for a pulmonary sequestration or bronchogenic cyst. Differential diagnosis of a congenital hernia is important.
