Key result
Childhood thoracic calcifications most commonly reflect prior infections rather than neoplasms or metabolic disorders.
Why the study?
Thoracic calcifications in children occur in various locations and have diverse causes, but detailed characterization to aid diagnosis is needed.
The shape and location of thoracic calcifications in children provide important diagnostic clues for underlying infectious, neoplastic, or metabolic diseases.
Answers are grounded in this paper and cite their sources.
May aid differential diagnosis via calcification patterns in children; leaves open prospective validation of criteria.
Thoracic calcifications are found in the following locations: mediastinum, lung, pleura, cardiovascular system, and thoracic wall. The calcifications of the mediastinum include mostly inflammatory lesions and malignant neoplasms. Pulmonary calcifications are mainly inflammatory lesions and metastases of osteosarcomas. Where the cardiovascular system is concerned, the most common calcifications are those of the heart relating to tumors or surgery. Calcifications of the aortic wall and valve calcifications can be found. In the thoracic wall there are calcifications of the bone and of soft tissues. The knowledge of shape and location is very useful for the diagnosis of the underlying disease. Calcifications in the thorax are frequently manifestations of previous infectious processes. Less often, they may be due to neoplasms, metabolic disorders, or previous medical therapy.

Hoeffel et al. (2002) conducted a review in Thoracic calcifications. Thoracic calcifications in childhood are frequently manifestations of previous infectious processes, and less often due to neoplasms, metabolic disorders, or previous medical therapy.
