Hydrops of the gall bladder associated with Kawasaki syndrome

Acute hydrops of the gall bladder has been reported in Kawasaki syndrome (KS) (Mucocutaneous lymph node syndrome/MCLS) as a major component of abdominal crises. We report 2 cases of KS where hydrops of the gall bladder was not associated with abdominal pain and was diagnosed by ultrasonography. In additional, one of these cases had ischemia involving the penoscrotal region secondary to vascular involvement.
