Clinicopathological study of tuberculous brain abscess

Area of Science:

• Neurology
• Infectious Diseases
• Pathology

Background:

• Central nervous system tuberculosis remains a major cause of morbidity globally.
• Tuberculous abscess is an uncommon but critical manifestation of CNS tuberculosis.
• It clinically, radiologically, and histologically mimics pyogenic abscesses, complicating diagnosis.

Purpose of the Study:

• To review the clinical, radiological, and histopathological spectrum of tuberculous abscesses.
• To identify diagnostic clues for tuberculous abscesses.
• To emphasize the importance of accurate diagnosis for appropriate therapy.

Main Methods:

• Retrospective review of 21 tuberculous abscess cases over 13 years (1995-2007).
• Analysis of clinical presentations, radiological findings, and histopathological features.
• Microscopic and culture-based demonstration of acid-fast bacilli.

Main Results:

• Histopathological findings included palisading epithelioid cells and foamy histiocytes surrounding neutrophilic exudate.
• Acid-fast bacilli were essential for confirming the diagnosis.
• Accurate diagnosis requires a high index of clinical suspicion, especially in endemic areas.

Conclusions:

• Tuberculous abscess diagnosis relies on characteristic histopathology and confirmation of acid-fast bacilli.
• Early and accurate diagnosis is crucial for effective treatment of central nervous system tuberculosis.
• Clinical vigilance is paramount in tuberculosis-endemic regions.
