Cavernous hemangiomas are benign tumors that exceptionally affect the cranial bones. The first description of this type tumor was in 1845 by Toynbee. A review literature reveals less than 100 published cases and a growing trend every year. Total surgical excision is treatment choice, prognosis after complete excellent, with recurrence usually rare. We present case 57-year-old patient painless left frontal bone, slow growth osteolytic characteristics from neuro-radiological point view. lesion...

Chordoma is a malignant tumor that usually involves the axial skeleton, and its origin related to notochord remnants. In cervical spine they represent 5% of all chordomas. Cervical chordoma present high rate recurrence given their location growing in highly risky anatomical region with complex anatomy. We report young female chordoma, involving C7-D1 vertebrae discussing challenges this intervention. There currently controversy over type surgical modality: block resection versus...
