Atypical aggressive vertebral hemangioma of the sacrum with postoperative recurrence: A case report

Figure 1 Computed tomography and magnetic resonance imaging. A and B: Sagittal and axial computed tomography of the lumbosacral spine showed osteolytic bony destruction at S1 and S2 with preservation of the sacral crest; C–F: On sagittal magnetic resonance imaging, the lesion appeared isointense on T1-weighted sequences and heterogeneously hyperintense on T2-weighted and short inversion time inversion recovery sequences. The lesion exhibited heterogeneous contrast enhancement and involved the S1 endplate and S2 vertebral body. A soft tissue mass compressed the thecal sac.

Figure 2 Hematoxylin-eosin staining results (× 200). The photomicrographs (200 ×) demonstrate blood-filled channels of different diameters with an area of inflammatory necrosis (arrows).

Figure 3 Follow-up magnetic resonance imaging. Sagittal magnetic resonance imaging 6 mo after surgery showed an enlarged sacral mass and thecal sac compression.
