Echocardiography showed a homogeneous, echo-dense mass that was compliant with
rhabdomyoma, measuring approximately 7x9 mm in the right atrium extending into the right ventricle through the tricuspid annulus.
The present report describes a multifocal distribution of neoplastic nodules, the largest of which was in the right ventricle; however, MCEWEN (1994) reported that
rhabdomyoma is more common in the left ventricle, but also it can be observed in the interventricular septum and the right ventricle (TANIMOTO & OHTSUKI, 1995).
At 6 months of age, echocardiography revealed a further decrease in
rhabdomyoma size (13.8 x 12.1 mm); the lesion occupied a smaller portion (about 50%) of the mitral annulus (Figure 3(a)).
It depends largely on the tumour location: the patient may be asymptomatic if the tumour is located far from the outflow tract, as in the case of the
rhabdomyomas. When the tumour is located within these flow paths, it can generate their obstruction and therefore produce moderate to severe hemodynamic disorders.

rhabdomyoma. Acta Derm Venereol 2015; 95: 243-4.
Rhabdomyomas are a group of benign tumors that show skeletal muscle differentiation.
For instance, cardiac
rhabdomyomas may be identified with antenatal fetal ultrasound or in the first year of life.
In tuberous sclerosis, a cardiac
rhabdomyoma is the only sign that can be detected prenatally.

rhabdomyoma of the head and neck: a clinicopathologic and immunophenotypic study of 24 cases," Human Pathology, vol.
An echocardiogram revealed multiple echogenic masses in the ventricles which were consistent with cardiac
rhabdomyoma. An ultrasound of the brain revealed periventricular calcification.
Cardiac
rhabdomyoma can be found in 50%-65% of patients with TS [10].
Lesions appearing as swelling on the dorsum of the tongue usually mimic hemangioma, lymphangioma,
rhabdomyoma, neuroma, or neurofibroma.
