Motion sickness susceptibility due to a small hematoma in the right supramarginal gyrus.
We describe a unique case of a woman who twice experienced episodes of susceptibility to motion sickness that lasted for several months. Both times a small hemorrhage from a cavernous angioma in the supramarginal gyrus (SMG) was detected by MRI. Because the SMG is part of area 7, which belongs to a network of multisensory visual-vestibular cortical areas, we conclude that a small lesion there can cause motion sickness susceptibility.
