Diagnosing tuberculosis by fine-needle aspiration biopsy
American Family Physician
|January 1, 1982
Summary
Percutaneous fine-needle aspiration biopsy is effective for diagnosing active pulmonary tuberculosis. This method confirmed the disease when other tests failed, identifying acid-fast bacilli and growing Mycobacterium tuberculosis.
Area of Science:
- Pulmonology
- Infectious Diseases
- Diagnostic Pathology
Background:
- Pulmonary tuberculosis diagnosis can be challenging, often requiring invasive procedures.
- Conventional methods may not always yield definitive results for active disease.
Observation:
- A case report details a patient with suspected active pulmonary tuberculosis.
- Conventional diagnostic approaches were insufficient to confirm the disease.
Findings:
- Percutaneous fine-needle aspiration biopsy of a suspicious lung lesion was performed.
- Direct examination of the aspirate revealed acid-fast bacilli.
- Culture of the aspirate confirmed Mycobacterium tuberculosis growth.
Implications:
- Fine-needle aspiration biopsy is a valuable tool for diagnosing pulmonary tuberculosis when other methods fail.
- This minimally invasive technique aids in prompt and accurate identification of Mycobacterium tuberculosis.
- It supports timely initiation of appropriate treatment for patients with difficult-to-diagnose tuberculosis.
