Learning objectives To distinguish between different types of pulmonary calcifications based on their morphology and etiology To identify the most common mechanisms of pulmonary calcifications To differentiate malignant from benign calcification in a pulmonary nodule To understand the clinical implications of different types of pulmonary calcifications, their management, and prognosis
Read more Background Pulmonary calcifications exhibit diverse morphologies and clinical significance. They can serve as markers of chronicity and severity, ranging from scattered, post-infectious changes found incidentally to chronic, rare diseases characterized by diffuse calcifying changes and poor prognosis.To better understand the prognosis, it is important to recognize the two most common mechanisms of pulmonary calcifications: metastatic calcifications, which involve the deposition of calcium salts in healthy lung tissue and are associated with systemic disturbances in calcium and phosphorus metabolism, and dystrophic calcifications,...
Read more Findings and procedure details For the purpose of this poster, we divided the pulmonary calcifications into three main groups: calcified solitary pulmonary nodules, scattered pulmonary calcifications, and diffuse pulmonary calcifications. Calcified solitary pulmonary noduleThe most reliable imaging features of benign pulmonary nodules with calcifications are a typical benign calcification pattern and no growth on follow-up scans over 2 years. Benign calcified nodule Typical benign features are calcifications occupying more than 10% of the nodule volume and with central, diffuse, popcorn-like or laminated calcification patterns.Popcorn-like calcifications and fatty...
Read more Conclusion It is essential to distinguish between the different forms of pulmonary calcification as the diagnosis impacts the treatment and follow-up regimen.
