pulmonary siderosis
Toddler with
hemoptysis and anemia. Initial CXR AP (left) shows diffuse alveolar infiltrates primarily in the upper lobes. CXR AP obtained a week later (right) shows resolution of the findings. The diagnosis was pulmonary hemosiderosis.

hemosiderosis • Idiopathic pulmonary hemosiderosis - Ganzer Fall bei Radiopaedia
Pulmonary hemosiderosis (PH) refers to iron deposition within the lung. It can be divided into two main types:
- primary pulmonary hemosiderosis
- pulmonary hemosiderosis associated Goodpasture syndrome
- pulmonary hemosiderosis associated with hypersensitivity to proteins in cow's milk (Heiner syndrome)
- idiopathic pulmonary hemosiderosis (IPH)
- secondary pulmonary hemosiderosis: often due to mitral stenosis
Terminology
Although the term “siderosis” strictly just means any deposition of surplus iron in the body, when used as a stand-alone term it usually refers to pulmonary siderosis.
Radiographic features
General
It is usually characterized by:
- small, ill-defined pulmonary nodules or
- coarse reticular areas of increased opacity with a bias for the middle and lower lung regions
- pulmonary ossification (especially when related to mitral stenosis): manifests as dense 1-5 mm nodules, mainly in the middle and lower lungs, with a tendency for confluence and the occasional presence of trabeculae
