Male patient aged 52 years old, presented by long standing headache and signs of increased intracranial pressure with history of prior excision of glioblastoma multiformis. A, B Axial pre and post contrast T1W images show: an intra-axial SOL occupying left parietal lobe showing mixed solid and cystic components with surrounding mild perifocal edema and exerting mass effect in the form of effacement of cortical sulci. The lesion display mixed heterogeneous SI on T1WI and showing faint enhancement on CE-T1WI. C, D Axial pre and post contrast FLAIR images show: The lesion appear of mixed heterogenous SI on precontrast FLAIR images and showing more evident and intense enhancement on CE-FLAIR image in comparison with post contrast T1W image denoting superiority of CE-FLAIR in assessment of lesion activity. E, F Pre and post contrast FLAIR at same level: measurements of the SI, denoting the difference between pre and post contrast and confirms the presence of enhancement (CEI = 739, Lesion to background contrast ratio = 1.8). G, H Pre and post contrast T1WI: measurements of the SI in pre and post contrast images (CEI = 328, Lesion to background contrast ratio = 0.65). Final diagnosis: Residual/Recurrent Glioblastoma Multiformis
