Left Atrial Myxoma in a Child: An Uncommon Presentation of a Rare Tumour in Early Age

Myxomas are rare tumours but are the most common benign tumours of the heart. They can arise from any heart chamber. However, they arise more frequently from the left atrium. They have rarely been described as originating in early age. A case of left atrial myxoma successfully removed using cardiopulmonary bypass in a 8-year-old child is presented. Review of the literature emphasizes the rarity and clinically aggressive behavior of this tumor in this age group. The object of this case report is to present myxoma in children and to evaluate possible differences between young and adult patients.

Benign Tumours

Myxomas are the most common benign tumours of the heart, majority of them arise from left atrium. They can have varied presentations, with asymptomatic patients to be picked up in routine screening at one end of spectrum to dangerous embolic manifestations at the other end of the spectrum. We report a case of left atrial myxoma distorting the mitral valve apparatus causing severe eccentric mitral regurgitation. Patient underwent complete surgical excision of the tumour along with mitral valve repair.

Abstract Background Myocarditis is an uncommon, potentially life-threatening disease that presents with a wide range of symptoms. In acute myocarditis, chest pain (CP) may mimic typical angina and also be associated with electrocardiographic changes, including an elevation of the ST-segment. A large percentage (20–56%) of myxomas are found incidentally. Case summary A 62-year-old female presenting with sudden onset CP and infero-lateral ST-elevation in the electrocardiogram. The diagnosis of ST-elevation myocardial infarction was presumed and administered tenecteplase. The patient was immediately transported to a percutaneous coronary intervention centre. She complained of intermittent diplopia during transport and referred constitutional symptoms for the past 2 weeks. Coronary angiography showed normal arteries. The echocardiogram revealed moderate to severe left ventricular systolic dysfunction due to large areas of akinesia sparing most of the basal segments, and a mobile mass inside the left atrium attached to the septum. The cardiac magnetic resonance (CMR) suggested the diagnosis of myocarditis with concomitant left atrial myxoma. The patient underwent resection of the myxoma. Neurological evaluation was performed due to mild vertigo while walking and diplopia in extreme eye movements. The head magnetic resonance imaging identified multiple infracentimetric lesions throughout the cerebral parenchyma compatible with an embolization process caused by fragments of the tumour. Discussion Myocarditis can have various presentations may mimic acute myocardial infarction and CMR is critical to establish the diagnosis. Myxoma with embolic complications requires emergent surgery. To the best of our knowledge, this is the first case reported in the applicable literature of a myxoma diagnosed during a myocarditis episode.
