Unexpected death from hepatic abscess 16 months after toothbrush ingestion.

The development of a hepatic abscess secondary to foreign body (FB) ingestion remains rare in forensic practice. Herein, we present a case of a prisoner who died in the hospital and a forensic autopsy was performed to confirm the cause of death. A 14.5-cm-long toothbrush handle was found in the duodenum and had penetrated the right lobe of the liver, consistent with the repeated abdominal pain in his clinical history. The clinical history and investigation confirmed that he had ingested the toothbrush handle 16 months prior. This case highlights a rare complication of intentional ingestion of foreign bodies, and pathologists should be aware of this rare entity which links hepatic abscess and FB ingestion.
