The spectrum of extrapulmonary tuberculosis

A Baydur

    The Western Journal of Medicine
    |April 1, 1977
    PubMed
    Summary

    Extrapulmonary tuberculosis (EPTB) diagnosis is often delayed due to non-specific symptoms. High clinical suspicion is crucial for early recognition and treatment of EPTB, which can mimic various diseases.

    Area of Science:

    • Infectious Diseases
    • Pulmonology
    • Clinical Medicine

    Background:

    • Incidence of extrapulmonary tuberculosis (EPTB) remains constant despite declining pulmonary tuberculosis.
    • Delayed recognition of EPTB is common when symptoms are non-respiratory.
    • EPTB should be considered in differential diagnoses for bone, joint, genitourinary, and central nervous system (CNS) diseases.

    Purpose of the Study:

    • To identify factors contributing to delayed recognition and diagnosis of extrapulmonary tuberculosis.
    • To analyze the clinical presentation and diagnostic challenges of EPTB.

    Main Methods:

    • Retrospective study of 62 patients with extrapulmonary tuberculosis from 1969-1972.
    • Review of patient records for presenting symptoms, diagnostic findings, and treatment outcomes.

    Main Results:

    • CNS, skeletal, and genitourinary tuberculosis each accounted for approximately 25% of cases.
    • Presenting symptoms were diverse and non-specific, including fever, weight loss, and neurological abnormalities.
    • Chest roentgenograms were abnormal in most patients, but a normal chest X-ray does not exclude EPTB.

    Conclusions:

    • A high index of suspicion is essential for diagnosing EPTB due to its varied presentation.
    • Early recognition and treatment, particularly for disseminated EPTB, can be lifesaving.
    • Diagnostic confirmation relies on mycobacterial culture from various bodily fluids and tissues.
