Ultrasound-Guided (USG) Aspiration From Sacroiliac Joint in Tuberculosis Is Rare: An Atypical Case Report From a Developing Country

TL;DR

This case report describes a rare instance of tuberculosis in the sacroiliac joint diagnosed using ultrasound-guided aspiration in a young man from a developing country.

Contribution

The paper presents a rare case of sacroiliac joint TB diagnosed using a minimally invasive ultrasound-guided aspiration technique.

Findings

USG aspiration successfully obtained fluid for diagnosing TB in the sacroiliac joint.

Sacroiliac TB can present without classic symptoms, requiring alternative diagnostic methods.

Early diagnosis through minimally invasive techniques can improve outcomes in TB-endemic regions.

Abstract

Tuberculosis (TB) in the musculoskeletal system is rare, though it is an emerging health concern in many developing countries. Sacroiliac joint (SIJ) TB is uncommon. This report highlights the use of ultrasound-guided (USG) aspiration to diagnose SIJ TB. We report a 23-year-old boy who presented with low back pain and localized tenderness over the SIJ. Initial imaging showed signs of inflammation. USG aspiration was performed successfully to obtain fluid for microbiological analysis, and laboratory investigations confirmed the presence of Mycobacterium tuberculosis. Sacroiliac TB often presents in the absence of classic symptoms, and minimally invasive procedures like USG aspiration can play a role in providing rapid diagnosis and treatment. Early identification and appropriate management can prevent further complications and improve patient outcomes in regions where TB remains endemic in the world.
