• We reported thirteen cases of bilateral stringhalt associated with Hypochaeris radicata that occurred in horses in Uruguay during a severe drought in the summer of 2023. All horses were affected chronically and progressively by bilateral hyperflexion of hindlimbs. In two severely affected horses, the main histological lesions included neuronal chromatolysis and axonal spheroids in the ventral gray horn in the lumbar and sacral spinal cord and axonal degeneration and digestion chambers in ventral roots fibers and long peripheral nerves. We suggest that in addition to injuries to peripheral nerves, lesions in the spinal cord play an important role in the clinical signs of stringhalt in horses. [Display omitted] •This is the first report of bilateral stringhalt associated with Hypocheris radicata in Uruguay and the second in South America.•Outbreaks are linked to severe drought in the summer.•Complete spinal cord examinations are mandatory for this condition.•Degenerative neuronal lesions occur in the ventral gray horn.
