This report demonstrates pulmonary haemorrhage as a differential cause of anaemia. Idiopathic pulmonary hemosiderosis is a rare disease in children; it is classically described as a triad of haemoptysis, pulmonary infiltrates on chest radiograph, and iron-deficiency anaemia. However, anaemia may be the only presenting feature of idiopathic pulmonary hemosiderosis in children due to occult pulmonary haemorrhage. In addition, the serum ferritin is falsely high in idiopathic pulmonary hemosiderosis which increases the diagnostic difficulty. We recommend that pulmonary haemorrhage be suspected in any child presenting with iron-deficiency anaemia and persistent bilateral pulmonary infiltrates.

Idiopathic pulmonary hemosiderosis (IPH) is an uncommon chronic disorder in children. It is characterized by recurrent pulmonary hemorrhage and may result in hemoptysis and pulmonary insufficiency. The most common hematologic manifestation of IPH is iron deficiency anemia. The etiology of IPH is not known and its diagnosis may be difficult due to the variable clinical courses. The most helpful signs for identifying IPH are iron deficiency anemia and recurrent or chronic cough, hemoptysis, dyspnea, wheezing. We report here 5 pediatric cases of IPH presenting with iron deficiency anemia and without pulmonary symptoms. Mean corpuscular volume was low in all patients; iron was low in 4 out of 5 cases; total iron binding capacity was high in all of them; ferritin was low in 3 patients. At follow up, none of them had responded successfully to the iron therapy. Although they didn't present with pulmonary symptoms, chest radiographs incidentally revealed diffuse reticulonoduler shadows in all of them. Computed tomography revealed diffuse ground-glass opacities, consolidation, increased density. The diagnosis was confirmed by the detection of hemosiderin-laden macrophages in bronchoalveolar lavage fluid and gastric aspirate. If patients with iron deficiency anemia don't respond to iron therapy, they should be examined for IPH. Chest radiographs should be taken even in absence of pulmonary symptoms. Early diagnosis is important for a timely management of IPH.
