Drumstick Symptom

The drumstick sign, also known as papillary mesomegaly, is a variable asymmetrical dilatation of the adnexal branches of the pulmonary artery observed in a number of heart and lung diseases.

It is a pathognomonic sign of rheumatic tricuspid valve disease (i.e., tricuspid sign) and its complications, such as bacterial endocarditis, perigyme membrane and fibroelastic aneurysm, as well as vibration pulmonary disease and physiological pulmonary congestion due to mitral stenosis. Another variant of the manifestation of this symptom is observed in congenital non-rheumatic tricuspid valve disease - a defect of the tricuspid aortic valve. Other causes of the syndrome: mediastinal tumor, lymphadenopathy, metastatic tumor, periarteritis nodosa, coarctation of the aorta.
