Case report: multi-modality imaging of a right ventricular fibroma in a teenager.

Background: Cardiac fibroma is a rare primary benign tumour of the heart. It often causes arrhythmia, endangers the lives of patients, and has a worse prognosis than other benign tumours. We report a 14-year-old female patient with a right ventricular fibroma. Various preoperative imaging examinations showed that the lesion was benign, and postoperative pathology confirmed that the lesions were fibroma. Case summary: A 14-year-old female patient visited her doctor for more than 5 months because of a heart murmur. Echocardiography revealed a slightly hyperechoic mass in the right ventricle, and on myocardial perfusion contrast imaging, the lesion showed equal enhancement. And the lesion also showed enhancement on contrast-enhanced gated cardiac computed tomography (CT). Contrast-enhanced magnetic resonance imaging (MRI) of the heart revealed that the lesion was isointense on T Discussion: Cardiac fibromas are histologically benign, but they can cause obstruction and malignant arrhythmia. The gold standard for diagnosing fibroma is pathology. However, in the absence of pathology, it is necessary to use various imaging methods to evaluate the lesions to distinguish between benign and malignant tumours.
