case_images: The cervical magnetic resonance imaging (MRI) [Figure 1] showed an intradural extramedullary anterior/left sided C2-C4 heterogeneous mass (i.e., 12 x 16 mm) markedly compressing the cord.
case_images: The pathologic examination at HE (Hematoxylin and Eosin) stain at x200 magnification reveals a notable proliferation of blood vessels. These vessels exhibit dilated lumens, which are prominently filled with red blood cells, indicating vascular congestion. The walls of these vessels are thickened and fibrous, suggesting a chronic process or significant fibrosis.

case_images: Pathologically, the tumor proved to be a cavernoma [Figure 2].
case_images: Sagittal (a) and axial (b) sections of a cervical spine magnetic resonance imaging on T2-weighted imaging (WI) (a) and T1-WI (b) showing a complete removal of the cavernoma.
