The heterogeneous lesion within the left frontoparietal white matter shows susceptibility, consistent with intraparenchymal haemorrhage. On the postcontrast imaging, there is an irregular enhancing rim, which extends toward the ventricle. Significant surrounding T2 hyperintense signal abnormality is noted. There is local mass effect, with sulcal effacement. No subfalcine line or transtentorial herniation. The lesion is solitary, with no further intracranial mass identified. Periventricular white matter T2/FLAIR hyperintensity is consistent with chronic small vessel ischaemia. No intracranial aneurysm or other vascular abnormality is demonstrated.
Conclusion: Left frontoparietal tumour, with intratumoural haemorrhage. The location and solitary nature favour high-grade glioma (glioblastoma) over metastasis.
