Overview

Splenic abscess is an uncommon and lifethreatening condition.

Classification

  • Unilocular abscess
  • Bilocular abscess
  • Solitary abscess
  • Multiple abscesses

Pathophysiology

Splenic abscess can result from various sources such as

  • Splenic trauma or splenic laceration
  • Hematogenous spread of bacteria
  • Contiguous spread of bacteria

Risk Factors

Common risk factors of splenic abscess include:[1]

  • Diabetes mellitus
  • Immunocompromised conditions such as AIDS[2]
  • Tunerculosis
  • Concomitant liver disease such as cirrhosis
  • Malignancies

Epidemiology and Demographics

Incidence

Indceidence of spelenic abscess varies between 0.1% to 0.7%.[3][4]

Case Fatality Rate

Splenic abscesses are associate with increased morbidity and mortality.

Diagnosis

History and Symptoms

Major symptoms of splenic abscess include:

  • Fever
  • Abdominal pain
  • Nausea and vomiting

Physical Examination Findings

Abdominal Examination

  • Tender splenomegaly

As the clinical features of splenic absecess are non specific and vague such as abdominal pain, fever and vomiting, that makes diagnosis is challenging and relied on imaging modalities. Imaging studies such as ultrasound, computerized tomography made the diagnosis early and more accurate that reduces morbidity and mortality.[5]

Laboratory Tests

Blood Tests

  • CBC with differential
  • Erythrocyte sedimentation ratio (ESR)

Treatment

Antimicrobial Regimen

Percutaneous Drainage

  • First line of treatment for splenic abscess
  • Safe and effective than surgery in both unilocular and bilocular abscesses.
  • Preserves spleen

Open Drainage

Surgery

  • Definitive treatment for splenic abscess
