|
Differential Diagnosis Also see: HNPP pathology |
MYELIN PATHOLOGY: Teased fibers  Tomaculae: Focal myelin thickening Common in HNPP Paranodal demyelination (Lower axon) |
from R Schmidt
 Thick myelin sheath due to multiple layers of folded myelin |
|
 Folding of myelin sheath: Outside axon or invaginating into axon (Right) |

Low power view: Two axons with tomaculae One thinly myelinated axon |
