Autoinfarcted wandering spleen and fatal pneumococcal sepsis in an infant.

A wandering or ectopic spleen, a rare congenital condition caused by improper fixation of the ligamentous attachments, was identified during a postmortem examination of a 10-month-old female who had died of Streptococcus pneumoniae sepsis. The wandering spleen was autoinfarcted and adherent to the left hepatic lobe, with resultant functional hyposplenism.
