چکیده

we report a 73-year-old woman with primary left atrial rhabdomyosarcoma and its 1h mr spectroscopy (mrs) findings. the tumor showed a 2.8 cm sized lesion in the posteroinferior atrial wall on mri. 1h mr spectra were acquired using a point-resolved spectroscopy (press) sequence with electrocardiographic (ecg) gating and respiratory motion. the use of 1h-mrs allowed the quantification of triglyceride (tg) peak groups at 0.9 and 1.3 ppm, and unsaturated group of lipids at 2.1 ppm, creatine (cr) at 3.0 ppm, and choline (cho) at 3.2 ppm. the percentages of the myocardial metabolites based on water-peak in the interventricular septum were tg 18.4%, cr 1.6%, cho 3.3% and unsaturated group 4.0%, whereas the rhabdomyosarcoma showed tg 118.8%, unsaturated group 5.1%, cr 1.3%, cho 3.5% and the olefinic components of fatty acid at 5.4 ppm 24.5%. this case demonstrates that 1h-mrs is potentially useful to diagnose the rhabdomyosarcoma by quantifying the myocardial metabolites which are important biomarkers for heart function and diseases.

Myocardial Metabolic Abnormality in a Primary Left Atrial Rhabdomyosarcoma: Localized 1H MR Spectroscopy

We report a 73-year-old woman with primary left atrial rhabdomyosarcoma and its 1H MR spectroscopy (MRS) findings. The tumor showed a 2.8 cm sized lesion in the posteroinferior atrial wall on MRI. 1H MR spectra were acquired using a point-resolved spectroscopy (PRESS) sequence with electrocardiographic (ECG) gating and respiratory motion. The use of 1H-MRS allowed the quantification of triglyce...

Left atrial rhabdomyosarcoma.

A 27-year-old man complained of frequent chest pain and recurrent syncope for 3 months. He was in mild respiratory distress with a respiratory rate of 20/min and a heart rate of 94 bpm, regular in rhythm. His blood pressure was 120/70 mm Hg. Cardiac auscultation revealed a distinct early diastolic click followed by a grade 2/5 diastolic decrescendo murmur at the apex that was variable in charac...
