Abstract

Intra-abdominal tuberculous lymphadenitis can mimic a variety of other abdominal disorders such as pancreatic cancer, metastatic lymph nodes, or lymphoma, which can make a proper diagnosis difficult. A correct diagnosis of intra-abdominal tuberculous lymphadenitis can lead to appropriate management. Endoscopic ultrasonography (EUS)-guided needle biopsy may be the procedure of choice for tissue acquisition when onsite cytopathology examination is unavailable because it is essential to obtain sufficient material suitable for the examination using an ancillary method, such as flow cytometry, molecular diagnosis, cytogenetics, or microbiological culture. We report a case of intra-abdominal tuberculous lymphadenitis diagnosed using an EUS-guided, 22-gauge histology new needle biopsy without an onsite cytopathology examination.

  • Fig. 1 Clinical findings. (A) Chest X-ray showing multiple variably sized calcified nodules in both upper lobes. (B) Upper endoscopy showing a 3×3 cm intraluminal protruding mass with normal overlying mucosa in the cardiac region of the lesser curvature of the stomach. (C) Abdominal computed tomography showing enlarged lymph nodes with rim enhancement and central low attenuation at the gastrohepatic ligament. (D) Endoscopic ultrasonography showing an enlarged heterogeneous hypoechoic lymph node.

  • Fig. 2 Pathological findings. (A) Tissue materials obtained using the endoscopic ultrasonography-guided ProCore biopsy. (B) Caseous necrotic material with no epithelioid granuloma (H&E stain, ×100). (C) Acid-fast bacillus (arrow) (Ziehl-Neelsen stain, ×1,000).
