Description
Samia Benlabed and colleagues report in 2026 a heart mass first taken for a giant blood clot that proved instead to be cancer growing inside the heart's vessels. Their patient had a metastatic solitary fibrous tumour, a rare growth of connective tissue. Scans showed a large, multi-lobed mass in the left upper heart chamber swinging through the mitral valve with each cycle. No irregular heartbeat rhythm or valve disease explained a clot, yet blockage or embolism risk was imminent.
Blood-thinning treatment began while a multidisciplinary team chose surgery, and the mass was removed. Lab examination showed a malignant growth of vessel-lining-like cells with severe abnormality and rapid division, and a positive marker test confirmed the fibrous tumour had spread there. The authors stress that ultrasound imaging and tissue proof play complementary roles when a mass could be either clot or cancer.
