Insights
Homocystinuria, a metabolic disorder, can manifest as a calcified right atrial mass. This rare presentation highlights unusual imaging findings in a patient evaluated for respiratory infection.
Area of Science:
- Cardiology
- Metabolic Disorders
- Genetics
Background:
- Homocystinuria is an inherited metabolic disorder caused by cystathionine β-synthase deficiency.
- This deficiency leads to elevated homocysteine and methionine, and reduced cysteine levels.
- These biochemical changes increase the risk of arterial and venous thromboembolism.
Observation:
- A case of homocystinuria presented with a calcified right atrial mass.
- The patient was initially evaluated for a lower respiratory tract infection.
- Unusual imaging findings were observed using multiple detector computed tomography and radiographs.
Findings:
- The study identifies a rare association between homocystinuria and a calcified right atrial mass.
- Imaging modalities revealed a unique combination of diagnostic features.
- This case underscores the diverse clinical manifestations of homocystinuria.
Implications:
- This case expands the understanding of cardiac manifestations in homocystinuria.
- It highlights the importance of considering metabolic disorders in patients with unexplained cardiac masses.
- The findings emphasize the utility of advanced imaging in diagnosing rare conditions.
Abstract:
Homocystinuria is a genetic inborn error of metabolism due to the deficiency of cystathionine β-synthase resulting in increased serum homocysteine and methionine and decreased cysteine which predisposes affected individuals to arterial and venous thromboembolic phenomena. We present a case of homocystinuria who presented to us as a calcified right atrial mass during the evaluation for lower respiratory tract infection. Our case reveals an unusual mix of findings using imaging with multiple detector computed tomography and radiographs.
