Going beyond the coronaries: Routine cardiovascular risk assessment reveals rare incidental thymoma.

Thymomas are rare anterior mediastinal masses that present with local or paraneoplastic symptoms. Definitive diagnosis requires tissue sampling but early detection leads to early intervention and improved outcomes. We present a case where routine cardiovascular risk assessment identified an incidental and rare thymoma. Final specimen pathology revealed a Thymoma WHO Type AB (30% A, 70% B). Routine cardiovascular risk assessment which often includes coronary artery calcium scanning and cardiovascular computed tomographic angiography may reveal pathology beyond the coronary arteries. Early detection of asymptomatic mediastinal masses facilitates early intervention and can improve outcomes.
