Cardiac Malignant Peripheral Nerve Sheath Tumor Accessed By F-FDG PET/CT.

This is a case report of a patient presenting an extremely rare cardiac malignancy: malignant peripheral nerve sheath tumour. The F-fluorodeoxyglucosis positron emission tomography associated to computed tomography (F-FDG PET/CT) accesses the tumour anatomy and metabolic activity, thereby making it possible to characterize a malignant neoplasm noninvasively. The diagnostic approach with F-FDG PET/CT spared the heart from a likely futile invasive procedure when detecting a distant metastasis and changed the biopsy site and therapeutic planning.
