CTICasesMetastatic Calcification in Dialysis
Imaging findings
Chest and spine CT show calcification of the dura within the spinal canal, a porcelain left atrium, calcification of the aortic and pulmonary arteries, and prominent airway cartilage calcification in a patient on long-term hemodialysis.
Key takeaways
Long-standing renal failure and hemodialysis can lead to abnormal calcium-phosphate product and metastatic/dystrophic calcification. This can manifest as calcification of the dura mater, left atrial wall (porcelain atrium), and tracheobronchial tree.
