Caseous Necrosis of Mitral Annulus : A Rare Cause of Stroke

Abstract EN

The current report describes a rare case of a caseous necrosis presenting as a pseudotumor in ventricle, revealed by stroke.

Cerebral MRI, showing multiples lacunes, evocates a cardioembolic mechanism.

Transthoracic and transesophageal echocardiography demonstrate a large hyperechogenic mass fixed to the posterior mitral valve and annulus while thoracic tomography revealed a fully calcified lesion, at the mitral annulus, evocative of caseus necrosis.

Medical therapy was preferred (anticoagulation), because of her age and the decaying nature of surgery.
