Other musculoskeletal symptoms referable to limbs(729.89) [729.89], Reason for Study: ^Reason: new right frontal mass History: LLE weakness There are irregular margin heterogeneously enhancing intra-axial masses one on the right middle frontal gyrus with the surrounding edema and another lesion on the right post central gyrus extended toward right superior parietal lobule. Both lesions show mixed signal intensities with enhancement. The right post central gyrus lesion shows restricted diffusion with subtle increase in CBV on perfusion imaging indicating high cellularity mass lesion instead of ischemic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable except subtle mass effect toward right lateral ventricle. There are multiple small signal voids within the right middle frontal gyrus lesion indicating intra-tumoral hemorrhages.The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Multifocal irregular margined mixed enhancing masses with surrounding edema, differential diagnosis include multifocal primary intraaxial high grade glial tumor. Metastatic tumors are also one of differential diagnosis.
