Mitral valvular cyst mimicking a solid mass: misdiagnosis with imaging modalities

Area of Science:

• Cardiology
• Pathology
• Medical Imaging

Background:

• Mitral valve masses can present diagnostic challenges.
• Distinguishing benign from malignant cardiac masses is crucial for patient management.

Observation:

• An 80-year-old patient presented with a mitral valvular mass on imaging.
• The mass mimicked a solid tumor but was asymptomatic.

Findings:

• Histopathological evaluation of the resected mitral valve mass revealed a cyst.
• Echocardiography and other imaging modalities can lead to misdiagnosis of mitral valvular masses.

Implications:

• Mitral valvular cysts should be considered in the differential diagnosis of cardiac masses.
• Accurate histopathological diagnosis is essential, especially in asymptomatic individuals.
• This case underscores the limitations of imaging in definitively characterizing mitral valve lesions.
