Cardiac fibroma

Presentation

Chest pain

Patient Data

Age: 40 years
ct

An intramural mass originates from  the free wall of the left ventricle. The mass is isodense to the ventricular wall and contains calcification.

mri

The mass is isointense to the myocardium with linear calcification. It is isointense to the myocardium on steady-state free precession and doesn't cause contraction deformity. Late enhancement is due to high fibrous and collagen contents.

Usually fibroma doesn't show enhancement in first pass perfusion images due to high fibrous contents.

Case Discussion

This is a case of pathologically proven fibroma. 

Key facts:

  • intramural mass emanating the free wall of the ventricles
  • left side more common than right
  • isodense to the myocardium on CT
  • may be hypointense in T2 due to high fibrous and collagen content
  • calcifications in 25%
  • late enhancement is due to high fibrous content
