Echocardiography revealed a 1.5 x 1 x 1 cm hyperechoic mass on the posterior mitral leaflet in a patient with severe tophaceous gout, suggesting a rare mitral valve tophus.
Case Report (n=1)
No
This case highlights that gouty tophi can rarely present as hyperechoic masses on cardiac valves, and gout should be considered in the differential diagnosis of such echocardiographic findings.
A few cases of cardiac valve tophi have been reported in literature. In this case report, the echocardiographic characteristics of the hyperechoic mass in the posterior leaflet mitral valve, intact mitral valve ring, and the occurrence of severe tophaceous gout arthritis suggested the diagnosis of a gout tophus on the mitral valve.

Rohani et al. (2012) conducted a case report in Severe Gout Tophaceous Arthritis (n=1). Severe tophaceous gout was evaluated on Echocardiographic detection of mitral valve mass. Echocardiography revealed a 1.5 x 1 x 1 cm hyperechoic mass on the posterior mitral leaflet in a patient with severe tophaceous gout, suggesting a rare mitral valve tophus.
