Magnetic resonance imaging with angiography identified a superior sagittal sinus thrombosis as the likely explanation for her symptoms. Possible causes are considered, and previous reports of the neurotoxicity of agents used in the treatment of leukemia are reviewed.

Is it implying that neuropathy does not occur in patients with erythema nodosum leprosum given the drug or is it that Waters and leprologists who use thalidomide are unable to detect symptoms and signs of nerve damage?
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
