Pasteurella multocida Splenic Abscess Causing Fever of Unknown Origin: Report of One Case

Area of Science:

• Infectious Diseases
• Bacteriology
• Clinical Case Reports

Background:

• Pasteurella multocida is a known cause of various human infections.
• Splenic abscesses are uncommon, with few documented cases caused by Pasteurella multocida.
• Primary splenic abscesses can present as fever of unknown origin (FUO).

Purpose of the Study:

• To report a rare case of splenic abscess caused by Pasteurella multocida.
• To emphasize the potential of Pasteurella multocida as an etiologic agent in primary splenic abscesses presenting as FUO.
• To highlight the diagnostic and management considerations for such cases.

Main Methods:

• Case report of an 81-year-old male patient presenting with FUO.
• Investigation and diagnosis of a splenic abscess.
• Treatment involved laparoscopic drainage and antibiotic therapy.

Main Results:

• A splenic abscess caused by Pasteurella multocida was identified in an immunocompetent host with type II diabetes and a synthetic arterial graft.
• The patient showed a positive response to laparoscopic drainage and a 20-day course of antibiotics.
• No specific portal of entry for the organism was identified.

Conclusions:

• Primary splenic abscess should be considered in the differential diagnosis of FUO.
• Pasteurella multocida is a potential, albeit rare, causative agent for splenic abscesses.
• Prompt diagnosis and appropriate management, including drainage and antibiotics, are crucial for favorable outcomes.
