The Discovery
A man in his 60s was rushed to a hospital in Japan after passing out. Despite doctors' efforts, he passed away from sepsis (a life-threatening reaction to an infection). It wasn't until a post-mortem examination that forensic pathologists discovered the source of the problem: a 9cm aluminium eyeliner pencil lodged inside him.
How it happened
The eyeliner had been inserted into his rectum (likely during sexual activity) years prior. However, it didn't just stay there:- Perforation: The pencil was pushed so hard that it pierced through the wall of his rectum and into his bladder.
- The Stone: Once the tip of the eyeliner was inside the bladder, mineral deposits from his urine began to crystallize around it. Over time, this formed a massive 6.5cm bladder stone (about the size of a large lemon) that was literally "stuck" to the eyeliner.
