Infectious Mononucleosis-Induced Splenic Infarction: Perhaps More Common in Healthy Individuals Than Previously...

Area of Science:

• Infectious Diseases
• Hematology
• Virology

Background:

• Infectious mononucleosis (IM) is a common syndrome typically caused by Epstein-Barr virus (EBV).
• IM usually presents with fever, pharyngitis, and lymphadenopathy, and is generally self-limiting.
• Rare complications of IM can affect multiple organ systems.

Observation:

• Splenic infarction is a rare complication associated with EBV-induced IM.
• Historically, IM-induced splenic infarction was considered infrequent and primarily seen in patients with hematologic conditions.
• This case report details splenic infarction in a young, otherwise healthy male patient.

Findings:

• The study challenges the notion that IM-induced splenic infarction is rare and limited to immunocompromised individuals.
• It suggests that splenic infarction may occur more frequently in healthy patients with no prior medical history.
• A case of splenic infarction in a young adult with no history of coagulopathy is presented.

Implications:

• These findings suggest a need to reconsider the prevalence and risk factors for splenic infarction in EBV-induced IM.
• Clinicians should maintain a high index of suspicion for splenic infarction in patients with IM, even those without apparent risk factors.
• Further research is warranted to elucidate the mechanisms and incidence of IM-associated splenic infarction in the general population.
