Abstract:

Hypertension in pediatric neuroblastoma can be challenging to manage due to its multifactorial etiology. We present a 3-year-old girl who presented with cardiogenic shock, echocardiographic evidence of dilated cardiomyopathy, right renal artery stenosis, and elevated catecholamines. Somatostatin receptor (SSTR) PET/CT revealed intense tracer uptake in a right adrenal mass and a low-grade diffuse myocardial uptake, suggestive of inflammatory myocarditis. This unusual finding highlights the potential role of SSTR PET/CT in detecting signs of myocarditis, with myocardial SSTR uptake as a possible biomarker of cardiac inflammation.

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
