Mediastinal widening on chest radiography caused by combined aortic valve disease and primary large B-cell lymphoma.

Poststenotic aortic root dilatation in patients with aortic valvular stenosis may result in mediastinal widening on chest radiograph. Main differential diagnosis of mediastinal widening is a tumour. In fact, besides atypical chest pain or dyspnoea at exertion secondary to compression of intrathoracic structures in the latter, symptoms may be absent. We report a case of combined aortic valve disease and additional primary large B-cell lymphoma.
