(A) Cranial CT scan (bone window) showing a right frontoparietal junctional area mass with distending growth, accompanied by osteolytic changes, showing the phenomenon of "daylight radiation". (B) Cranial CT 3D reconstruction.

Bone changes in the right frontoparietal junction, benign bone tumor, or meningioma cranial changes were also observed (Figure 1).

T2 signal shadows were seen, and irregular or radial crown short T1 and short T2 signal shadows were seen within it, with restricted diffusion of the edges, local thinning of the bone cortex, protrusion to the inside and outside, and displacement of the adjacent brain tissue by pressure. The right frontoparietal bone was occupied, mostly benign, and cranial hemangioma was considered (Figure 2). The patient's serum biochemical index results, including blood routine tests, C-reactive protein, tumor markers, and coagulation function, were all normal.

On the first day after surgery, the cranial CT was reviewed, and the surgical result was good with satisfactory reconstruction (Figure 3).
Postoperative pathology report, suggesting cranial cavernous hemangioma. Histopathologic view of the resected tumor: hematoxylin and eosin (H&E) staining.

The postoperative pathology was confirmed as cranial cavernous hemangioma (Figure 4), and the patient was discharged 11 days after surgery in good condition.
