Focal cortical dysplasia (type I)

Focal swelling of left temporal lobe. Gyriform low T1w/high T2w signal, predominantly in the subcortical white matter with blurring of GM/WM junction. Remainder of parenchyma normal, with normal mesial temporal lobe appearances. Normal CSF configuration. No abnormal restricted diffusion. No contrast enhancement or SWI abnormality.
Case Discussion
Signal abnormality in the left temporal lobe without associated positive or negative mass effect. Likely focal cortical dysplasia (Blumcke type I), although a low grade DNET remains in the differential list.
