Ruptured idiopathic left ventricular false aneurysm of the free wall associated with Takayasu's arteritis in a young child.

The co-existence in a young child of long-standing Takayasu's arteritis, chronic myocarditis and a false aneurysm of the left ventricle raises the possibility that a common inflammatory process may have accounted for all three findings. The unique combination of pathology observed in this patient may provide further evidence that widens the spectrum of cardiac involvement associated with Takayasu's disease to include the myocardium.
