Abstract

Here, we report the existence of meningeal lymphatic vessels in human and nonhuman primates (common marmoset monkeys) and the feasibility of noninvasively imaging and mapping them in vivo with high-resolution, clinical MRI. On T2-FLAIR and T1-weighted black-blood imaging, lymphatic vessels enhance with gadobutrol, a gadolinium-based contrast agent with high propensity to extravasate across a permeable capillary endothelial barrier, but not with gadofosveset, a blood-pool contrast agent. The topography of these vessels, running alongside dural venous sinuses, recapitulates the meningeal lymphatic system of rodents. In primates, meningeal lymphatics display a typical panel of lymphatic endothelial markers by immunohistochemistry. This discovery holds promise for better understanding the normal physiology of lymphatic drainage from the central nervous system and potential aberrations in neurological diseases.

  • Recent magnetic resonance imaging studies in the living human brain and marmosets utilized a combination of gadolinium-based contrast agent (Gadovist) and blood-pool contrast agent (Vasovist) to demonstrate existence of the meningeal lymphatic system.

  • The dural lymphatics are a critical transport system of macromolecules, interstitial fluid, and CSF from the CNS into the cervical lymph nodes.

    “The dural lymphatics are now recognized as a critical transport system of macromolecules, interstitial fluid, and CSF from the CNS into the cervical lymph nodes (Aspelund et al., 2015; Absinta et al., 2017; Louveau et al., 2018; Ahn et al., 2019).”

  • The extent of enhancing tissue within parasagittal dura does not resemble previously reported appearance of true dural lymphatic vessels (tubular-shaped, sub-millimeter, near venous sinus wall) nor classical MRI appearance of arachnoid granulations bulging into venous sinuses.

    “The extent of enhancing tissue within parasagittal dura does not resemble the previously reported appearance of true dural lymphatic vessels, which are tubular-shaped structures of sub-millimeter cross-sectional diameter near the venous sinus wall3,4,11, and also far from the classical MRI appearance of arachnoid granulations bulging into venous sinuses12.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
