Proton magnetic resonance spectroscopy ( 1 H MRS) has the potential to provide a noninvasive assessment of hepatic lipid composition. The spectral resolution of in vivo clinical MR data is currently limited by the magnetic field strengths available and by motion artifact. Therefore, interpretation o

Abstract
A variety of lesions may present as intraventricular masses in children. We report quantitative proton magnetic resonance spectroscopy (MRS) of two intraventricular tumors of the choroid plexus: choroid plexus carcinoma (CPC) and choroid plexus papilloma (CPP). Both lesions were characterized by high levels of choline‐containing compounds and a complete absence of creatine and the neuronal/axonal marker N‐acetyl aspartate. The CPC showed higher levels of choline compared to the CPP, and it also had elevated lactate. These preliminary results, if confirmed in a larger cohort of patients, indicate that proton MRS may have a role in the presurgical diagnosis of choroid plexus tumors in children, which may also have important implications for therapy and prognosis.
