case_images: Plain radiography of lumbar area showing bony erosion and widening of the canal (scalloping) at the level of L3 vertebra (arrow).

case_images: On plain radiography, evidence of vertebral scalloping and widened foramen at the level of L3 was considered probable (Figure 1).
case_images: Sagital magnetic resonance images showing an intradural mass at the level of L3, isointense to spinal cord on T1-weighted (A) and iso-hyperintense on T2-weighted sequences (B). T1-weihted axial image demonstrating the intradural mass pushing the caudal roots to the side of the canal (C).

case_images: Magnetic resonance imaging (MRI) revealed an intradural, well circumscribed mass at the level of L3, isointense to spinal cord on T1-weighted and isointense to hyperintense on T2-weighted sequences (Figure 2).
case_images: Post-gadolinium enhancement revealed in sagital (A), coronal (B), and axial (C) magnetic resonance images of this lesion.

case_images: Post gadolinium injection images showed remarkable homogenous enhancement (Figure 3).
case_images: Photomicrograph of the lesion demonstrating a lobule composing of small capillary vessels lined by a layer of endothelial cells. The fibrous capsule (arrow), interlobular septa (right-pointing arrowhead), and a capillary lumen (left-pointing arrowhead) are disclosed in the picture. H & E, original magnification, x4 (A) and x40 (B).

case_images: Histopathological assessment revealed encapsulated mass with lobular components containing small size capillary vessels lined by a single layer of flattened endothelial cells (figure 4).
case_images: A large vessel with endothelialized wall in the middle of the specimen, probable to be the feeder vessel. H & E, original magnification, x20.

case_images: A large vessel with structured endothelial components was seen in the middle of the sample, most likely to be the feeder vessel (Figure 5).
