Jacksonian Somatosensory Seizures as the Sole Manifestation of Chronic Subdural Hematoma

To the Editor.— We present the first reported case, to our knowledge, in which jacksonian somatosensory seizures were the sole manifestation of a contralateral chronic subdural hematoma. The somatosensory seizures resolved following evacuation of the hematoma. Report of a Case.— A previously well, 43-year-old, right-handed male welder began to note transient paresthesias of the left hand, arm, and face. With each episode, which lasted from 30 to 60 s, the symptoms would spread from the distal left phalanges to include serially the entire hand, arm, shoulder, face, and torso on that side. This temporal sequence never varied. Initially occurring once or twice daily, the episodes gradually increased in frequency to ten or more per day.
