Malignant peripheral nerve sheath tumor of the oculomotor nerve

WOS: 000238706600013PubMed ID: 16875338We present the short-term follow-up magnetic resonance (MR) studies and H-1-MR spectroscopy in a child with malignant peripheral nerve sheath tumor of the oculomotor nerve associated with other less aggressive cranial nerve schwannomas. The tumor revealed perineural extension and diffuse nerve involvement besides rapid growth. H-1-MR spectroscopy was helpful in excluding an intra-axial neoplasm with exophytic growth, mainly due to the absence of creatine and N-acetyl aspartate peaks, and markedly elevated choline peak
