A middle-aged man was presented with poor appetite, polyuria, polydrpsia, and headache. A sellar mass was found, along with total pituitary hypofunction and visual field defect. A biopsy of the lesion via the trans-sphenoidal approach showed inflammatory changes and granuloma formation. However, repeated cerebrospinal fluid and pathogenic examination of the pathological tissue showed no positive indications. The initial diagnosis considered autoimmune hypophysitis, and treatment of glucocorticoids combined with immunosuppressants was administered, which led to a temporary shrinkage of the lesion, but it gradually enlarged subsequently. After multidisciplinary discussion, a high possibility of pituitary tuberculosis infection was decided upon. After standardized anti-tuberculosis treatment was initiated, the lesion reduced noticeably and the patient′s condition improved. Pituitary tuberculosis infection is incredibly rare and extremely easy to misdiagnose. This case was diagnosed and treated in a timely and effective manner through a multidisciplinary approach, highlighting the importance of such an approach in dealing with rare diseases.
