Often a clinically silent condition, splenic infarct is associated most commonly with hematologic disorders. Although splenic infarct rates of 50% and 72% have been reported in chronic myelogenous leukemia and myelofibrosis, respectively, few large series describing this entity exist.

In 1998, Nores et al [12] reported 59 cases treated over a 30-year period at the University of California, Los Angeles (UCLA) and at the Cedars-Sinai Medical Center. In 1986, Jaroch et al [15] identified 75 patients through clinical or autopsy reports at the Cleveland Clinic and found only an additional 77 cases in the literature. Most of the current literature consists of case reports only.

The frequency of visualized splenic infarcts may be rising because of the following factors:

  • Increased radiologic imaging of patients (with subsequent increased incidental detection of splenic infarcts) [16]
  • Current standard of nonoperative management of blunt splenic injuries
  • Increased use of angiographic embolization for vascular splenic injuries [17]
