Primary Pulmonary Amebiasis Complicated with Multicystic Empyema.

Area of Science:

• Infectious Diseases
• Parasitology
• Pulmonology

Background:

• Amebiasis is a parasitic infection caused by Entamoeba histolytica.
• While often asymptomatic, it can lead to severe extraintestinal manifestations like liver abscesses or pulmonary involvement.
• Pleuropulmonary amebiasis is a rare but serious complication.

Purpose of the Study:

• To report a rare case of primary pleuropulmonary amebiasis.
• To emphasize the importance of considering amebiasis in pulmonary disease diagnoses, especially in endemic areas.
• To highlight successful treatment outcomes.

Main Methods:

• Case report of a 24-year-old male with Down syndrome presenting with severe pneumonia and empyema.
• Diagnostic investigation included pleural fluid analysis.
• Treatment involved surgical drainage and metronidazole therapy.

Main Results:

• Pleural fluid analysis confirmed Entamoeba histolytica cysts and trophozoites.
• The patient was diagnosed with primary pleuropulmonary amebiasis.
• Prompt response to surgical drainage and metronidazole treatment was observed.

Conclusions:

• Pleuropulmonary amebiasis should be considered in the differential diagnosis of severe pulmonary infections, particularly in endemic regions.
• Early diagnosis and appropriate treatment, including surgical intervention and antiparasitic medication, are crucial for favorable outcomes.
• Physicians should maintain a high index of suspicion for amebiasis in patients presenting with pulmonary disease, especially those from endemic areas.
