A Calcified Amorphous Tumor in the Left Atrium: A Case Report

Area of Science:

• Cardiology
• Radiology
• Pathology

Background:

• Calcified amorphous tumors (CATs) are uncommon, benign cardiac masses.
• Their etiology and typical presentation remain poorly understood.
• CATs are often found on the mitral valve or annulus.

Observation:

• This report details a rare case of a cardiac CAT.
• The mass was located in the left atrium of a 79-year-old female patient.
• Computed tomography (CT) and magnetic resonance imaging (MRI) were utilized for evaluation.

Findings:

• The study presents the characteristic CT and MRI findings of a left atrial CAT.
• It highlights imaging features that aid in differentiating CATs from other cardiac masses.
• Specific diagnostic criteria based on imaging are discussed.

Implications:

• This case contributes to the limited literature on cardiac CATs.
• Accurate identification via imaging can prevent misdiagnosis and unnecessary interventions.
• Further research into CAT pathogenesis may be warranted based on imaging characteristics.
