Here's an interesting case from a couple of decades ago. This patient sought treatment for painful swelling to his face and right temple. 11 days earlier, while drunk, he had tried to break up a fight in a pub and remembered banging his head against a wall. What had happened?

The doctors who examined him noticed 'a small, well-healed laceration at the right oral commissure and pus draining intraorally adjacent to the upper 3rd molar tooth.' There was no other medical history of note. So they drained the infected haematoma on his head. And found...

A 13-cm section of snooker cue! The patient had been attacked with it but was so drunk that he had not realised what had happened.

This enormous object had somehow remained embedded in his skull undetected for 11 days. Here is an artist's impression of the route it must have taken.

"The sensation of the patient, hitting his head, was almost certainly the tip of the cue impacting the underside of the dermis of the temporal scalp."

OUCH.

The object was removed successfully and the patient made a full recovery. This case report can be read here: https://www.ijoms.com/article/S0901-5027(05)00323-1/fulltext
