[Unilateral adrenal hemorrhage--a Waterhouse-Friderichsen syndrome?]

A 5-year-old girl presented with a clinical picture of rapidly progressing acute meningococcal sepsis. A routine bedside abdominal ultrasound examination which was done daily showed on the 2nd and 3rd hospital day massive right adrenal hemorrhage with extension into the retroperitoneal fat tissue and intraperitoneal space. The left adrenal gland remained unchanged.
