Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Axial T2 weighted (TR: 4250, TE: 106) images demonstrating hyperintense expansile osseous lesion with trabecular thickening involving the entire T4 vertebral body extending into the left posterior elements with extension into the bony spinal canal and left posterolateral paraspinal musculature causing compression of the thoracic spinal cord.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Sagittal T2 weighted (TR: 4866, TE: 113) images demonstrating hyperintense mass involving the T4 vertebral body with extension into the spinal canal. There is high signal within the spinal cord at the level of T4 consistent with spinal cord edema.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Precontrast axial (TR: 366, TE: 14) T1 weighted images depicting an initially hypointense soft tissue mass which involves the T4 vertebral body with extension into the spinal canal, postererior elements, and left paraspinous soft tissues.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Precontrast sagittal (TR: 500, TE:14) T1 weighted images depicting an initially hypointense soft tissue mass which involves the T4 vertebral body with extension into the spinal canal, postererior elements, and left paraspinous soft tissues.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Postcontrast axial (TR: 467, TE: 14) T1 weighted images depicting an avidly enhancing soft tissue mass after intravenous injection of 15cc OptiMARK (gadoversetamide). The mass involves the T4 vertebral body with extension into the spinal canal, postererior elements, and left paraspinous soft tissues.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Postcontrast fat-suppressed sagittal (TR: 400, TE: 14) T1 weighted images depicting an avidly enhancing soft tissue mass after intravenous injection of 15cc OptiMARK (gadoversetamide). The mass involves the T4 vertebral body with extension into the spinal canal, postererior elements, and left paraspinous soft tissues.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. GE Signa Excite 1.5 Tesla magnet. Sagittal Short T1 Inversion Recovery (STIR) (TR: 4900, TE: 54) images demonstrating high signal within the spinal cord at the level of T4 consistent with spinal cord edema.

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. Noncontrast axial CT images depicting an expansile lesion of T4 vertebral body with trabecular thickening and intervening decreased density giving the characteristic ``polka dot`` appearance compatible with an osseous hemangioma. Note the aggressive nature with soft tissue component extending and involving the spinal canal and posterior elements. (Scanner: GE LightSpeed Pro16; Protocol: Source axial image slice thickness: 0.63mm, kVp 120, mA 631)

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. Noncontrast coronal CT images depicting an expansile lesion of T4 vertebral body with trabecular thickening and intervening decreased density giving the characteristic ``corduroy cloth/jail bar`` appearance on coronal images compatible with an osseous hemangioma. Note the aggressive nature with soft tissue component extending and involving the spinal canal and posterior elements. (Scanner: GE LightSpeed Pro16; Protocol: Source axial image slice thickness: 0.63mm, kVp 120, mA 631).

Click 67-year-old woman with aggressive hemangioma of the thoracic spine and progressive paraplegia. Selected digital subtraction angiography (DSA) images at the T3-T4 vertebral level demonstrating abnormal pooling of contrast in the T4 vertebral body on early phase with accumulation of contrast on more delayed phases consistent with a hemangioma. The blood supply was mainly from the right supreme intercostal artery.
