case_images: (a, b) Coronal and sagittal lumbar CT (bone window) demonstrating an eccentric, expansile lytic lesion at the posterior aspect of the right L2 vertebral body extending along the right psoas muscle. It is causing mass effect on the right neural foramen. (c, d) Axial and coronal lumbar MRI with contrast showing a right paravertebral soft tissue lesion with heterogeneous signal intensity and enhancement at L1 to L3. There is spinal canal component at L2-L3 right neural foramen and epidural space involving the exiting nerve. It invaginates into the right psoas muscle and causes scalloping of the right vertebral body of L2 and L3. It measures about 9 x 6 x 4 cm in maximum diameters. (e) Hematoxylin and eosin stain (high power; magnification x200). Ganglioneuroma, mature: admixture of few mature ganglion cells and abundant atypical Schwann cells.
