Three patients developed prominent
neurologic symptoms and signs associated with
Schoenlein-Henoch purpura.
A 7 1/2-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.
