From the case:
Radial head fracture
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/17810/annotated_viewer_json?lang=gb"}
A large joint effusion is present, which is associated linear cortical breach of the radial head which appears undisplaced.

A faint fracture involves the lateral aspect of the head of the radius, without a significant articular step-off. This is consistent with a Mason type I fractures.
Case Discussion
Even when a fracture is invisible, a large elbow joint effusion in an adult, should be treated as a radial head fracture.
