Isolated body lateropulsion in a patient with pontine infarction.

A 72-year-old man with diabetes mellitus and hypertension was admitted to our hospital with lightheadedness. The patient showed lateropulsion to the right side, but his neurological findings were otherwise normal. Brain magnetic resonance images showed a fresh ischemic infarct in the left dorsal part of the lower pons. Body lateropulsion is characterized by an irresistible falling to one side and has been reported in lesions in several brain regions. However, it has rarely been reported in pontine lesions. We suggest that physicians should be aware that pontine lesions can cause isolated body lateropulsion without other neurological deficits.
