Background: case report of a rare congenital anomaly - the diverticulum of the right ventricle of the heart, revealed by echocardiography and magnetic resonance imaging (MRI) of the heart.

Aim: was to show possibilities in detection and differential diagnosis of diverticulum of the right ventricle.

Materials and methods: patient, 23 years, during examination after passed pneumonia, underwent echocardiography wich revealed an aneurysm of right ventricle. Patient underwent further examination: MRI of heart in T1-WS and T2-WS, «gradient echo» and dynamical regime (Cine-SSFP) in standard positions. Demonstration of diverticulum is based on reconstruction imaging (MPR). Results: due to MRI data, in right ventricle we found a bulging 1,2х2,0 cm with clear contours, wich decreased in systole with myocardum of right ventricle - «true diverticulum of right ventricle». We marked difficulties in the diagnosis associated with the paucity of clinical manifestations.

Conclusions: MRI made it possible to study individual morphological anatomy of the diverticulum, to demonstrate and to assess in detail the topography that helped to make decisions on further management of the patient.
