Primary lateral sclerosis (PLS), previously undescribed in children, is characterized by a spastic motor deterioration and pathologic demonstration of corticospinal tract degeneration. We report an infant who, before 12 months of age, developed a progressive motor disease characterized by generalized spasticity. He died at 47 months, and neuropathologic examination revealed only corticospinal tract degeneration. We conclude that this child had typical clinical and pathologic findings for PLS.

We report the clinical and neuroimaging findings of a mother and daughter with seizure disorders and band heterotopias seen on magnetic resonance imaging studies. These clinicoradiologic findings simulate those for a diagnosis of tuberous sclerosis complex. Clinicians should be aware of this migrational anomaly and its neuroimaging characteristics, as well as the potential for this specific migrational anomaly to be genetically transmitted.

Three patients developed prominent neurologic symptoms and signs associated with Schoenlein-Henoch purpura. A 71/2-year-old boy was seen with status epilepticus after a 2-week history of generalized headaches, irritability, and intermittent colicky abdominal pain. A left hemiparesis and a left homonymous hemianopia with a right gaze preference that were present on initial examinations gradually resolved, but a mild left arm paresis persisted. Cutaneous, renal, and joint involvement followed initial CNS manifestations. The second patient, a 7-year-old girl, had a complex partial seizure with secondary generalization and a postictal hemiparesis seven days after presentation with classic signs of Schoenlein-Henoch purpura. Behavioral changes were noted during the acute phase of the illness. The third patient, a 13-year-old boy, developed signs of a left brachial plexopathy and transient weakness of his right leg during a complicated course of Schoenlein-Henoch purpura. Review of the world literature indicates that headaches and mental status changes are the most frequent neurologic complications of Schoenlein-Henoch purpura, followed by seizures, focal neurologic deficits, mononeuropathies, and polyradiculoneuropathies. The vasculitis of Schoenlein-Henoch purpura can involve the nervous system and may add significantly to the morbidity of the illness.
