[Pulmonary varicosity, a rare reason of solitary nodule]

Pulmonary varicosity is a very rare entity. Beside congenital varices, most combined with other malformations of the pulmonary vessels, varicosities are described above all in connection with mitral insufficiency. Most cases with pulmonary varicosity are diagnosed by chance, because of absence of any symptoms or only slight symptoms respectively. We demonstrate our own case with respect to the diagnostic requirements (computerized tomography, multi-slice CT) and the differential diagnostic aspects.
