Background: Adrenocorticotropic hormone therapy for infantile spasms, including West syndrome, has been previously reported to induce seizures. We present the findings for a school-aged child with epilepsy who developed new focal seizures during adrenocorticotropic hormone therapy.
Case presentation: The Japanese patient had posttraumatic epilepsy and developed intractable focal seizures at the age of 13 years. Adrenocorticotropic hormone therapy was administered when the patient was 14 years of age. On day 10 of treatment, he developed new focal seizures, which were characterized by left arm contractions followed by movements of touching things with his right hand and writhing and rocking his body left and right and back and forth as automatisms. The focal seizures clustered for 40 minutes and disappeared after suppository administration of 10 mg diazepam. These focal seizures did not reoccur after more than 2 years of follow-up.
Conclusion: Adrenocorticotropic hormone-induced seizures can occur in children older than previously reported, and can occur in children with intractable seizures other than epileptic spasms.
