Caseous Necrosis of Mitral Annulus.

Balci S, Akkaya S, Ardali S, Hazirolan T - Case Rep Radiol (2015)

Bottom Line: Masses or mass-like lesions located in proximity to mitral valve encompass a wide range of differential diagnoses including neoplasias, abscesses, thrombi, and rarely caseous calcification of mitral annulus.Due to asymptomatic presentation, its diagnosis is usually incidental.Imaging in evaluation of mitral annulus caseous calcification is essential in order to prevent unnecessary operations.

ABSTRACT
Masses or mass-like lesions located in proximity to mitral valve encompass a wide range of differential diagnoses including neoplasias, abscesses, thrombi, and rarely caseous calcification of mitral annulus. Due to asymptomatic presentation, its diagnosis is usually incidental. Echocardiography is the first choice of imaging in evaluation. Cardiac computed tomography (CT) is helpful in establishing diagnosis by showing dense calcifications while cardiac magnetic resonance imaging (MRI) is used primarily as a problem solving tool. Imaging in evaluation of mitral annulus caseous calcification is essential in order to prevent unnecessary operations.

T1-weighted (a) and T2-weighted (b) turbo spin echo images show hypointense round mass-like lesion (black and white arrows). Delayed postcontrast cardiac MRI image (c) shows peripheral enhancement (black arrow). Multislice noncontrast computed tomography image (d) shows round calcification (black arrow) located in mitral annulus.

fig1: T1-weighted (a) and T2-weighted (b) turbo spin echo images show hypointense round mass-like lesion (black and white arrows). Delayed postcontrast cardiac MRI image (c) shows peripheral enhancement (black arrow). Multislice noncontrast computed tomography image (d) shows round calcification (black arrow) located in mitral annulus.

Mentions: A 76-year-old male patient with symptoms of tachycardia, palpitation, sweating, and headache was admitted to our hospital. His history for coronary or cerebral atheroslerotic disease was not remarkable. Physical examination revealed diastolic murmur. The transesophageal echocardiography demonstrated hyperechoic mass in posterior leaflet of mitral valve and mild mitral regurgitation. There was not accompanying leaflet prolapse or mitral stenosis. Cardiac magnetic resonance imaging (MRI) was performed for further evaluation. It showed a hypointense mass-like lesion of 2.5 × 2 × 3 cm. Lesion was hypointense in both T1- and T2-weighted sequences and showed peripheral enhancement in postcontrast delayed series. The aforementioned MRI findings were suggestive of caseous necrosis (Figures 1(a)–1(c)). Multislice computed tomography (CT) showed a calcified mass, confirming presumptive diagnosis of caseous necrosis (Figure 1(d)).
