An uncommon case of gall bladder mass: gall bladder tuberculosis.

Gall bladder tuberculosis (TB) is a rare entity and differentiation of gall bladder TB from gall bladder malignancy is difficult. We hereby present an unusual case of incidental diagnosis of gall bladder TB during the evaluation of a gall bladder with suspicion of gall bladder cancer in a 49-year-old woman. The diagnosis of gall bladder TB was made with fine needle aspiration cytology (FNAC) from the gall bladder mass as the disease was found unresectable after cross-sectional imaging. Even with the advancement of cross-sectional imaging, the differentiation of gall bladder TB from gall bladder malignancy is not possible without tissue diagnosis.
