Non-Familial Left Atrial Myxoma in an Adolescent: A Rare Mimic of Mitral StenosisNavin Agrawal, DM, Soumya Patra, Ashish Agarwal, Kamal Gupta, Sunil Srinivas, Rajni Sharma and Manjunath CN.
We are presenting a rare case of large non-familial left atrial myxoma in a fourteen year old girl which presented clinically
similar to severe mitral stenosis which was the first clinical differential diagnosis which was considered initially. She
had symptoms of progressively worsening orthopnea and exertional dyspnea since the last 2-3 months (NYHA class III
symptom status). The final diagnosis which was made after echocardiography was surprising and the girl was diagnosed
to have a large atrial myxoma which was causing obstruction of the mitral valve preventing normal inflow across the
mitral valve. The patient had no family history of being diagnosed of a cardiac tumor nor there were any cutaneous
manifestations in the form of lentigenes or any symptoms suggestive of and systemic or cerebral embolization of tumor
fragments. The patient subsequently underwent surgical excision of the tumor which was eventually confirmed to be an
atrial myxoma histopathologically. Presence of atrial myxoma in an adolescent patient is an extremely rare occurrence
and has seldom been reported.
Key words: Atrial myxoma, non familial echocardiography
