case_images: The patient underwent computed tomography (CT) scan of the abdomen/pelvis, which documented an enhancing extradural spinal lesion measuring approximately 2.3 x 1.5 cm at the level of the L1 and L2 vertebrae, resulting in severe central canal stenosis [Figure 1].

case_images: A supplemental magnetic resonance imaging (MRI) scan scan confirmed an enhancing "dumbbell shaped" 4.8 x 3.9 x 1.4 cm (CC x TV x AP) intraspinal extradural lesion centred at the L1/L2 level [Figure 2].

case_images: The patient underwent T12-L3 laminectomy with L1-L2 left facetectomy for excision of the tumor accompanied by T12-L3 instrumented fusion [Figure 3].

case_images: Histological examination showed fibroadipose tissue with diffuse proliferation of densely packed vascular channels closely associated with some arterioles and venules without any thrombosis [Figure 4].

case_images: Immunohistochemical staining found the endothelial cells to be CD31 immune-reactive [Figure 5].
