Figure 3. Spinal cord dorsal root ganglia.

(A) Normal anterior spinal cord nerve rootlets (arrow). (B) Atrophic posterior spinal cord nerve rootlets (arrow). (C) Spinal cord and coverings showing atrophic dorsal root ganglia (arrows). (D) Atrophic dorsal root ganglion showing marked neuronal loss with scant residual neurons (arrow in higher magnification main image; low-power whole dorsal root ganglion shown in inset). No evidence of satellite cell hypertrophy. (E) Cross-section of cervical spinal cord showing secondary demyelination of the posterior columns (arrows); ×20, Luxol fast blue.
