Abstract :
More than one trigger are known as responsible for acute glomerulonephritis in the pediatric age. The
most common infective trigger is beta-hemolytic Streptococcus group A (GAS) but various infective
agents, bacterial and viral, are capable of triggering the inflammatory process. We report a case of 5-
year-old child who developed an acute glomerulonephritis related to a GAS and Mycoplasma
pneumonia infection and Cytomegalovirus urine reactivation with ultrasound picture suggestive of
important kidney involvement. The case support the hypothesis of a relationship between multiple
infectious disease and immune-mediated and/or autoimmune mechanism whereas underling
mechanism is still unclear and highlights the possible use of ultrasound as a tool to assess the severity
of renal involvement.
