Pulmonary siderosis complicated with severe mycoplasma pneumoniae pneumonia: A case report.

Idiopathic pulmonary hemosiderosis (IPH) is a rare and fatal lung disease. Mycoplasma pneumoniae pneumonia (MPP) is the main community-acquired pneumonia among children aged 5 and above in China. We report the following case of IPH complicated with severe mycoplasma pneumoniae pneumonia(SMPP). An 8-year-old boy with cough and fever was diagnosed with IPH for 3 years and his chest computed tomography showed bilateral bronchopneumonia, lobular consolidation and subpleural interstitial fibrosis. As far as we know, IPH related to SMPP is rarely reported. In the high incidence period of MPP, clinicians and radiologists should be alert to the co-occurrence of IPH and SMPP.
