Multimodal imaging in the diagnosis of isolated left ventricular noncompaction

Left ventricular noncompaction (LNVC), first described in 1984, is a rare congenital cardiomyopathy that is thought to be caused by arrest of normal embryogenesis of the endocardium and the myocardium, and characterized by multiple prominent trabeculations with deep intertrabecular recesses. LVNC can be associated with other congenital cardiac abnormalities such as atrial septal defect and ventricular septal defect, but it can occur in isolation. The clinical manifestations of the disease are variable, ranging from no symptoms to signs of heart failure, systemic emboli, and ventricular arrhythmias. The diagnosis is established by two dimensional echocardiography or magnetic resonance imaging. We report the case of a 44-year-old man with LVNC and discuss the role of multimodal imaging in the diagnosis and assessment of the disease.

[Cystic lymphangioma: an unusual cause of lower limb lymphedema]

We report an unusual cause of unilateral lymphedema of the right limb rapidly increasing in a young woman. Ultrasonography ruled out the diagnosis of iliac deep venous thrombosis or extrinsic compression: the B mode scan revealed a mass located below the aortic bifurcation and along the iliac vessels, without any compressive effect. The lesion was heterogeneous associating both tissular and cystic aspects. The lower limb lymphoscintigraphy showed an interruption of the colloid circulation at the right iliac level. Computed tomography did not give any additional information. Magnetic resonance imaging before then after gadolinium showed typical aspects of cystic lymphangioma and confirmed the ultrasonography hypothesis. Considering that this tumor is benign, that surgery would be difficult because of the anatomic situation of the mass, and that post-operative involution of the edema is uncertain, the treatment was based on compressive stockings and regular follow up.
