Left ventricular diverticulum mimicking cardiac tumor

Maciej T Wybraniec et al. Echocardiography. 2017 Oct.

Abstract

Left ventricular (LV) diverticulum represents a rare and frequently asymptomatic congenital anomaly, which is incidentally discovered during routine transthoracic echocardiography. We present a case of a 66-year-old female patient who was admitted to the cardiology department due to incidental finding of a tumor-like mass associated with the posterior mitral leaflet. Preliminary echocardiographic evaluation revealed a solid structure, suspected of mitral annulus calcification or LV malignancy. However, cardiac contrast-enhanced computed tomography confirmed the presence of LV diverticulum, partially filled with calcified thrombus. Conservative management was recommended. This case underscores the importance of multimodality imaging for differentiation of LV tumor-like structures.

Keywords: computed tomography (CT); echocardiography; left ventricular aneurysm; left ventricular diverticulum; left ventricular mass; mitral annulus calcification.
