Disorder of brain, unspecified [G93.9] / Encounter for other preprocedural examination [Z01.818] / Unspecified convulsions [R56.9], Reason for Study: ^Reason: MRI brain stealth for surgery planning, no fiducials needed. Brain mass, presurgery day of surgery Multiple fiducial markers attached to scalp for the preparation of planned surgery.There is about 20.6mm x 30mm sized intra axial mass with enhancement on the right parahippocampal gyrus.The lesion shows high signal intensity on the T2 weighted images and demonstrated irregular shaped enhancing portion especially posterior mesial aspect of the mass.Though limited sequence, there is no definitive surrounding edema.Differential diagnosis include ganglioglioma, pilocytic astrocytoma, and pleomorphic xanthochromcytoma.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.
Right hippocampal gyrus intra axial mass with focal enhancement and subtle mass effects as described above.
