case_images: (a) Four-chamber echographic view shows a mobile left atrial mass (M) protruding into the left ventricle (LV) whose ultrasonic characteristics are consistent with a myxoma (LA: left atrium). (b) MRI performed in 2021 shows the mass (M) protruding through the mitral valve from the left atrium (LA) during systole (S) into the left ventricle (LV) during diastole (D). (c) MRI (sagittal T2- and T1-weighted images) performed in 2007 shows the first occurrence of a 17 x 14 mm left atrial mass (M). Video link on YouTube: https://www.youtube.com/watch?v=cPPDHg0cYZc.

case_images: The atrial mass was incidentally discovered by echography (Figure 1(a) (video link on YouTube: https://www.youtube.com/watch?v=cPPDHg0cYZc)). MRI (Figure 1(b)) revealed a large and mobile left atrial mass (32 x 35 mm) protruding through the mitral valve into the left ventricle in diastole and consistent with a myxoma as the patient reported a recent and insidious shortness of breath, with neither chest pain nor fever and weight loss. At the age of 18, she had developed a left atrial myxoma (17 x 14 mm) attached to the interatrial septum (Figure 1(c)) which was surgically removed.
case_images: (a) Operative views. Left part: after right atriotomy and before septotomy: a small 7 x 6 mm mass (M) enshrined below the insertion of the previous pericardial patch (P) used to reconstruct the interatrial septum 13 years earlier. Right part: after septotomy, a gelatinous and mobile mass (M) is easily visualized into the left atrium. (b) Cervical MRI performed 11 months after the resection of the myxoma depicts a 20 x 18 mm cervical intradural spherical mass (M) at the C2-3 level with signs of spinal cord compression. Left part: T2-weighted sagittal image. Right part: T1-weighted sagittal image.

case_images: After resection, examination of the right atrial chamber showed a small (7 x 6 mm) gelatinous mass enshrined below the insertion of the previous pericardial patch and easily resected (Figure 2(a)). Eleven months later, while reporting dysesthesia with a moderate cutaneous hypoesthesia around the neck, the patient underwent a cervical MRI which disclosed a 20 x 18 mm cervical intradural spherical mass at the C2-3 level with signs of spinal cord compression and without any osteolytic component (Figure 2(b)).
