[Bilateral pulmonary embolism mimicking acute chest syndrome in an adolescent with sickle cell disease]. / Embolie pulmonaire bilatérale mimant un syndrome thoracique aigu chez un adolescent drépanocytaire.

Pulmonary embolism is a life-threatening and potentially lethal disease. Its incidence in children with sickle cell disease is probably underestimated and pediatric case reports in the literature are rare. Moreover, symptoms can mimic an acute chest syndrome. We report on the case of a 17-year-old boy with SS sickle cell disease, admitted for chest pain with dyspnea and tachycardia. Pulmonary angiography revealed a partial bilateral obstructive pulmonary embolism. We did not find any deep venous thrombosis or thrombophilia. The progression was rapidly favorable with anticoagulant therapy. We recommend a pulmonary angiography for any chest pain that does not evolve favorably in a child with sickle cell disease. Large series of pediatric patients would be useful to establish diagnostic and therapeutic guidelines.
