Splenic Abscesses in the Pediatric Population: A Literature Review of an Uncommon Entity.

Splenic abscess in the pediatric population is a rare but serious condition. Its incidence is reported to be between 0.05% and 0.7%. Splenic abscess is an infectious suppurative process with a discernible macroscopic filling defect in the subcapsular space or spleen parenchyma. Causes include bacterial infection through the hematogenous route or from locoregional spread such as the gastrointestinal tract, septic emboli, trauma, sickle cell anemia, and malarial infestation. Diagnosis is often delayed due to non-specific signs and symptoms. Symptoms include fever, abdominal pain, and palpable left upper abdominal swelling. Ultrasound and cross-sectional imaging such as CT scans are useful for the diagnosis of splenic abscess but contrast-enhanced CT scans are considered the gold standard because of their high sensitivity and specificity. Treatment options range from antimicrobial therapy, percutaneous drainage, and aspiration to surgical interventions such as splenectomy. As it has a high mortality rate, prompt diagnosis and appropriate treatment are essential for optimal outcomes.
