We report the case of a 45-year-old Colombian female with a 3-month history of @entity10 , @entity448 , @entity1295 , and @entity892 in addition to left @entity2103 2  weeks prior to presentation. On examination, visual fields and fundi were normal, but left abducens and @entity2103 were noted. An MRI scan disclosed a sellar mass with suprasellar but neither parasellar nor retrosellar extension. The mass was interpreted as a @entity977 and resected via the transsphenoidal approach. Histologic examination revealed @entity39 in a background of normal pituitary gland tissue. The differential diagnosis includes @entity378 , @entity370 , @entity364 , syphilis, granulomatous @entity792 , @entity1222 , and @entity10630 . Staining for tubercle bacilli (acid fast and fite) as well as for fungi (GMS) was negative and PCR for mycobacteria showed the same result. Postoperative empiric treatment with antituberculous medication resulted in resolution of the @entity129 within a 1  month. The diagnosis of inflammatory/infectious @entity738 can be difficult to diagnose preoperatively and occasionally even postoperatively. A high index of suspicion should be maintained especially in those @entity1 with a history of a @entity262 or in regions endemic in granulomatous @entity166 .
