Unilateral adrenal tuberculosis whose computed tomography imaging characteristics mimic a malignant tumor: A case report

Figure 1 Microscopic examination of fine needle aspiration biopsy of the right adrenal gland showed Langerhans cells. A: Epithelioid cells; B: Necrosis; which were suggestive of tuberculosis infection.

Figure 2 These were contrast-enhanced axial computed tomography images of the abdomen. A: Showed an isointense mass of 1.5 cm in the right adrenal gland; B: Showed an irregular mass of 6.0 cm × 4.5 cm with uneven density (20-30 HU in the central and 80-90 HU in the peripheral) in the right adrenal gland, while the left one was normal; C: Showed that the mass became smaller (2.7 cm × 2.4 cm) after anti-TB therapy for a total of 15 mo; D: Showed a slight enlargement of the right adrenal gland after about three years’ anti-TB therapy.
