CTICasesLeft atrial mural calcification in end-stage renal disease
Imaging findings
Serial CT scans show progressive, dense calcification of the left atrial wall and pulmonary vein ostia (porcelain left atrium), in a patient with end-stage renal disease on chronic hemodialysis and renal osteodystrophy (with sternal brown tumors).
Key takeaways
Left atrial mural calcification (porcelain left atrium) classically occurs in chronic rheumatic mitral stenosis, but can also develop in end-stage renal disease on long-term hemodialysis due to metastatic calcification from secondary hyperparathyroidism.
