An atypical presentation of atypical Kawasaki disease.

Kawasaki disease (KD) is a well-known inflammatory disorder that, despite its classic description, can pose a diagnostic challenge. We report a case of a 3-year-old girl who presented to the emergency department with a limp and urinary incontinence who was ultimately diagnosed with KD. She was found to have a large coronary artery aneurysm on echocardiogram. We discuss the challenges in diagnosing incomplete KD.
