A one year old girl was presented at the ER because of a large perineal impalement injury. She required surgery and a stoma was placed. Initially no causative mechanism for the injury was described. Further history-taking revealed she had jumped in the bath on a castle-shaped shampoo bottle. This explanation matches both the injury and the developmental stage of the child. With this case we aim to underline the importance of detailed history-taking in order to distinguish between accident and abuse. The history-taking should include a detailed history of the mechanism of trauma, in order to relate this to the injury and the developmental stage of the child. If there is a suspicion of child abuse risk factors for child abuse should be sorted out. If there is doubt about the relation between the mechanism described and the injury, a forensic expert should be consulted.
