Fatal amoebic liver abscess: an autopsy study.

Area of Science:

• Medicine
• Pathology
• Infectious Diseases

Background:

• Amoebic liver abscess (ALA) is a common helminthic infection, particularly in tropical regions.
• Diagnosis can be challenging due to varied clinical presentations.
• Delayed or missed diagnosis can lead to severe complications and increased mortality.

Purpose of the Study:

• To analyze the clinicopathological features of amoebic liver abscess in autopsy cases.
• To identify factors contributing to diagnostic errors and fatal outcomes.

Main Methods:

• Retrospective autopsy study of 20 cases with confirmed amoebic liver abscess.
• Review of clinical records, gross pathological findings, and histopathological examination.

Main Results:

• Mean age of patients was 32 years; 20% presented with jaundice, 20% with fever and abdominal pain, and 30% with dysentery.
• Mean duration of illness was 7.2 days; all patients were emaciated with enlarged livers (mean weight 2680g).
• Abscesses were predominantly single, involving the right lobe (75%), with a mean size of 13cm; complications included rupture (15%), pulmonary involvement (15%), and colonic ulceration (50%) with perforation in 10%.

Conclusions:

• Amoebic liver abscess can present with non-specific symptoms, mimicking other conditions like viral hepatitis or enteric fever, leading to diagnostic delays.
• Unusual presentations and associated complications significantly contribute to the high mortality rate observed in this autopsy series.
• Emphasizing awareness of atypical presentations and prompt diagnostic workup is essential for managing amoebic liver abscess effectively.
