Background:

Kawasaki disease shock syndrome is a rare presentation of Kawasaki disease, in which cardiovascular manifestations associated with elevated inflammation biomarkers that develop hypotension are observed. It is preceded by gastrointestinal and neurological manifestations, with an increased risk of coronary lesions and resistance to intravenous immunoglobulin.

Case report:

A 5-month-old male patient with a fever that had developed in the last week, gastrointestinal and neurological symptoms with hypotensive shock, urticarial rash, BCG lymphadenitis, and edema of palms and soles. Giant coronary aneurysms were evident, so Kawasaki disease shock syndrome was diagnosed, which was treated with corticosteroid pulse and intravenous immunoglobulin.

Conclusions:

Clinicians must suspect Kawasaki disease shock syndrome when there is hypotensive shock, and the gastrointestinal, neurological and mucocutaneous symptoms that are characteristic of the disease, especially in infants under one year of age. The timely treatment of this disease reduces severe complications.
