Associated with the Carney complex (a rare multiple endocrine syndrome featuring multiple cardiac myxomas and skin pigmentation).
• Mobile echogenic mass with a well-defined stalk—may obstruct the mitral valve
PLAIN FILM/CT
• Cardiomegaly with left atrial enlargement (splaying of the carina)
• Signs of mitral valve obstruction (pulmonary hypertension and pulmonary oedema from increased left atrial pressure)
• Soft tissue mass within the left atrium
• majority show heterogenous contrast enhancement on CT due to necrosis, cyst formation and haemorrhage
MRI
• T1 : hypo,T2 : hyper
Atrial myxoma. CT image demonstrating a soft tissue mass within the left atrium; this was proven to be an atrial myxoma.
