Noncompaction ventricular myocardium is an unusual cause of cardiomyopathy. It is association with congenital heart defects, most often with outflow obstructive lesions or coronary anomalies. However, no factor could explain the arrest of development of myocardial structure (isolated form). The pathogenesis of isolated noncompaction is thought to be an arrest in endomyocardial morphogenesis. It has been reported that myocardial noncompaction could present as acquired disease. The most common site of involvement is the left ventricle, with right ventricular involvement being reported in a few cases. In this report, we present a case with noncompaction of the right ventricle (RV). Cardiac computed tomography angiography and magnetic resonance imaging demonstrated morphological abnormalities of the RV.

The rupture of a popliteal artery aneurysm is very rare, and can lead to serious complications if untreated. Any reports of a huge pseudoaneurysm, following rupture of the popliteal artery aneurysm could not be found in a review of the literature. A pulsatile huge mass leading to a deep venous thrombosis, was observed in a 74 years old male patient who for 2 months had had a progressively swollen and painful left leg. On angiographic evaluation, the mass was found to be a pseudoaneurysm originating from a ruptured true aneurysm of the popliteal artery. There was also a small true aneurysm in the contralateral extremity at the same localization. Both the false, and true aneurysms were resected surgically and arterial continuity was established with a synthetic polytetrafluoroethylene graft.
