Summary
Amoebic liver abscess can mimic pneumonia, presenting with fever and respiratory symptoms. Early diagnosis using imaging and antibody tests, followed by amoebicidal treatment, is crucial for recovery.
Area of Science:
- Infectious Diseases
- Hepatology
- Radiology
Background:
- Amoebic liver abscess (ALA) is a serious condition often caused by Entamoeba histolytica.
- ALA can present with non-specific symptoms, leading to diagnostic challenges.
- Geographic origin and travel history are important factors in suspecting ALA.
Observation:
- Three patients initially diagnosed with pneumonia presented with symptoms suggestive of ALA.
- Common symptoms included fever, right-sided chest pain, elevated inflammatory markers, pulmonary infiltrates, and pleural effusion.
- Patients had recent or distant travel history to endemic or potentially contaminated regions (tropics, Morocco, Greenland).
Findings:
- Diagnostic confirmation involved identifying a liver cavity via imaging, detecting amoebic antibodies in serum, and observing a positive response to amoebicidal therapy.
- Two cases required closed drainage in addition to medical treatment.
- Delayed diagnosis can occur due to the varied and sometimes subtle presentation of ALA.
Implications:
- This case series highlights the importance of considering ALA in patients with pneumonia-like symptoms, especially those with relevant travel history.
- Prompt and accurate diagnosis of ALA is essential to prevent complications and ensure effective treatment.
- Radiological and serological investigations are key tools in differentiating ALA from other causes of similar symptoms.
