Atypical sessile cardiac myxomas can mimic other structures and cause recurrent embolic strokes, highlighting the need for advanced cardiac imaging in cryptogenic stroke evaluation.
Stroke is a major cause of death worldwide, with most cases being ischemic in presentation. Cardioembolic phenomenon contributes to a significant number of ischemic strokes. Cardiac myxomas, although generally benign, are the most common tumors arising in the left atrium. Left atrial tumors tend to grow into the atrial lumen and can cause symptoms similar to heart failure with mitral valve disease. Cardiac myxomas have typical pedunculated, gelatinous features and are at risk of microthrombi formation. However, when these typical features are not present, sessile cardiac myxomas can be mistaken for lipomatous hypertrophy of the interatrial septum. Embolic phenomenon from myxoma microthrombi can lead to serious neurological complications, which can be difficult to diagnose. We present a case of an 82-year-old male patient with multiple strokes and findings of left atrial myxoma with atypical features. This case illustrates the diagnostic challenge posed by atypical cardiac myxoma morphology leading to recurrent embolic stroke. Advanced cardiac imaging, beyond a transthoracic echocardiogram, may be warranted when evaluating cryptogenic stroke to rule out cardiac myxomas.
Alishala et al. (Thu,) conducted a case report in 82-year-old male patient with prior ischemic strokes and multiple comorbidities including hypertension, myasthenia gravis, prostate cancer, and history of renal cell carcinoma, with an identified left atrial sessile cardiac myxoma causing embolic stroke (n=1). Surgical resection of left atrial mass was evaluated on Successful removal of left atrial cardiac myxoma without perioperative complications. Surgical resection of a sessile left atrial cardiac myxoma was successfully performed in an 82-year-old male with multiple strokes, leading to uneventful recovery and diagnosis confirmation.
