RESUMO
Bone and joint pain are common causes of pediatric consultation for a variety of etiologies. The causes are mostly traumatic or infectious or have an inflammatory origin. Acute leukemia (AL) can sometimes begin with osteoarticular signs and radiological investigations such as magnetic resonance imaging (MRI) can help guide the diagnosis. We report on two cases of pediatric AL revealed by osteoarticular signs, with MRI helpful in the diagnostic procedure. In these children, the first signs were recurrent joint pain, with no blood count anomalies. There was a delay between the onset of arthralgia and diagnosis due to atypical presentation of the disease. MRI guided the investigations to the diagnosis of AL. The persistence of pain or inflammation must lead to considering a bone MRI and a complete blood count must be repeated in case of persistent inflammatory bone pain to avoid a missed diagnosis of blood disease.

A case of small bowel volvulus due to midgut malrotation in a 4 years-old child complaining of vomiting and abdominal pain. Diagnosis was made by a Doppler ultrasound showing the volvulus and the intestinal malrotation. We are discussing the interest of this technique.

The treatment of post-traumatic dislocation of the patella depends on careful examination. One should propose surgery in most cases, for not only one may leave a foreign body within the joint, but above all correction of the extensor apparatus is necessary in more than 50 p. cent of cases, to avoid a recurrence. The quality of the results depends on the preoperative analysis of the knee. Our study of 29 cases confirmed this.

Reduction in aneurysm size during the months after an endovascular graft placement generally is considered one of the criteria of success. We report the case of a patient with an abdominal aortic aneurysm rupture occurring 9 months after a bifurcated endovascular graft placement despite a greater than 45% reduction in size noted on contrast-enhanced computed tomography scan performed at 7 months. Biomaterial modifications of the stent and of the Dacron explanted stent-graft are analyzed.
