left frontal intra axial mass lesion, preop planning for biopsy. Intra axial T2 high signal intensity lesion involving left middle frontal gyrus and mid to lower pre central gyrus with gyral swellings are seen. On Gad enhancement images, there is almost no contrast enhancement was seen on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.There is localized retention cyst on the left anterior aspect of the sphenoid sinus.
Left middle frontal and pre central gyrus intra axial lesion with gyral swelling as described above.
