Repetitive Transcranial Magnetic Stimulation Induced Charles Bonnet Syndrome

We report the case of a 15-year-old girl who has been suffering from depression for 2 years without any medication. She was admitted to the local psychiatric hospital, and then she received 1 Hz rTMS with parameters of 1200 stimuli/day in 15 trains of 10 sec, at 120% stimulation intensity, once a day, and 5 days a week. rTMS was performed over the right dorsolateral prefrontal cortex. After 6 sessions, she developed severe complex and colored visual hallucinations. She described snakes crawling on the floor, dogs wagging their tails, unfamiliar humans dressed in red clothing and blue hats, ever-changing scenery such as forests of trees and purple flowers.
