- The right parietal extra-axial mass shows vivid enhancement on MRI too, and only minimal peripheral SWI artifacts. Imaging appearance still favors meningioma over meningeal metastasis.
- A further, vividly enhancing similar extra-axial lesion can be detected in the right temporal region, adjacent to the petrous ridge.
- However, the most concerning finding is a small about 3 mm cortical-subcortical left parietal enhancing lesion, best seen on T1 C+, but inconspicuous on postcontrast FLAIR. On SWI the lesion demonstrates signal loss, likely representing hemorrhage. The lesion is in retrospect (note: potential hindsight bias) discernible on the postcontrast CT too.
- On the border of the right cerebral peduncle and brainstem an ill-defined about 6 mm focus of increased enhancement can be seen, showing SWI signal loss.
