A delayed splenic hemorrhage from a subcapsular hematoma occurred in association with pregnancy. That rare complication carries a high mortality rate, is rarely diagnosed preoperatively and is correctly diagnosed only 20% of the time. The clinical setting and a high index of suspicion led us to investigate for the presence of a splenic hematoma. A computed tomographic scan was invaluable in establishing the diagnosis. We adopted a conservative approach and followed the patient's clinical course from 28 to 40 weeks' gestation, until she delivered vaginally. In general, patient management (conservative vs. splenectomy) and mode of delivery will depend on how close one is to the initial event, on the patient's and fetus's clinical condition and on the gestational age.
