Massive splenic infarct in a pediatric patient without predisposing factors

Splenic infarction is a rare entity in the paediatric age that, when found, is associated with other predisposing factors such as oncological, haematological or infectious diseases. It is whether asymptomatic or symptomatic with abdominal pain, fever and splenomegaly. There is no consensus on which is the best treatment option, in most cases deciding conservative or surgical management according to individual patient characteristics. We present the case of a patient with acute abdominal pain and fever with a diagnosis of massive splenic infarction without apparent aetiology that was managed conservatively with favourable evolution. It is important to consider this condition as a cause of abdominal pain associated with splenomegaly.
