Pineal parenchymal tumor – pro
MRI is the most sensitive method for the assessment of the spinal cord, meninges and nerve roots and the differentiation of the spinal lesions into intra/extra medullary and extradural. Because of its high sensitivity and the advances of the method, drop metastases can be easily diagnosed at an earlier stage than in the past, contributing to the selection of the appropriate treatment. Therefore, the entire neuroaxis should be investigated with MRI for the presence of intradural extramedullary lesions.
