When Tissue is an Issue: “Trident Sign” Enhancement Helps …
The “trident sign” caused by enhancement of the central canal and dorsal subpial spinal cord has recently been described as strongly suggestive of underlying sarcoidosis. This sign may be particularly useful in cases of isolated sarcoid myelopathy where biopsy is too high risk and there is no other extraneural tissues to investigate.

Jan 30, 2021 · Coronal T1 and FLAIR sequence showing a pontine lesion with a three-pronged lance appearance (trident sign). The trident sign is classically described in the axial plane but can be easily seen also in coronal plane. Hypoosmolality leads to the loss of protective osmolytes that regulate cell size and prevent pathological swelling.
