A biopsy-supported neurologic case favored a toxic cause of white-matter injury. Pathology did not identify benzodiazepines as the unique responsible exposure.
The patient had rapidly progressive neuropsychiatric decline and diffuse white-matter abnormalities. Extensive laboratory, CSF, imaging, and EEG investigations did not establish a clear alternative cause.
Brain biopsy showed spongiform leukoencephalopathy favoring a toxin-related process. The history included several possible exposures, including insecticides, nonapproved anabolic steroids, opioids, and benzodiazepines.
A pathology pattern can support an injury category without identifying the specific toxic agent. Multiple possible exposures and incomplete exposure quantification leave causal uncertainty.
This report cannot establish a benzodiazepine-specific injury rate or prove that a therapeutic exposure produces the same lesion. In a forensic analysis, separate the confirmed tissue findings from the suspected exposure mechanism. Preserve timing, dose information, co-exposures, testing, and alternative explanations rather than treating every drug listed in the history as an independently demonstrated cause.
