Bowler's thumb is an uncommon traumatic neuropathy of the thumb ulnar digital nerve. We present a case of bowler's thumb in an individual who is an avid bowler, however, only manifesting following an unrelated injury. We describe the clinical and imaging findings, differential diagnostic considerations, and the treatment options. Knowledge of this entity and its sonographic features is important in order to identify this uncommon entity.
