In the computed tomography images (a): an ICH located in the parietal lobe surrounded by circle edema. An ellipse entity that had the same density as the cortex can be seen in the anterior part of this lesion. In MRI images: this lesion can be significantly enhanced in the contrast sequence (b), with an extremely low signal in the T1 sequence (c), and in the T2 (d) and FLAIR (e) sequence the signals were still low, which were different from the previous literature.

T1 sequence, hypointense or isointense lesion with annularity hyperintense around on T2 and FLAIR sequence, and part of the lesion can be significantly enhanced on the contrast sequence. Thus, the modified diagnosis was the left parietal lobe tumor with ICH [Figure 1].
