Neoplasm of unspecified behavior of brain [D49.6], Reason for Study: ^Reason: brain lesion. Preop planning for biopsy History: headaches. Multiple fiducial markers attached on the scalp during the scan.There is ill defined mainly non enhancing, T2 high signal intensity mass on the left mesial temporal lobe involving para hippocampal and fusiform gyri although more sequences will be helpful for precise anatomical localization. The ventricles, sulci and cisterns are symmetric and unremarkable. 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.
Left mesial temporal lobe ill-defined nonenhancing mass which shows T2 high signal intensity is described above.
