Symptomatic hyperprolactinemia mimicking pituitary pathology in a child with Landau-Kleffner syndrome and autism spectrum disorder: case report
A 12-year-old girl with autism spectrum disorder, Landau-Kleffner syndrome, and intellectual disability developed galactorrhea, vision problems, and falls while taking risperidone, with laboratory findings showing elevated prolactin (40.2 ng/mL) but normal imaging excluding pituitary tumor. Switching from risperidone to olanzapine resulted in complete symptom resolution and prolactin normalization (2.2 ng/mL) within three months, highlighting the importance of monitoring prolactin levels in children on antipsychotic medication.
