A rare presentation of splenic tuberculosis with a pseudocyst.

Splenic tuberculosis is an unusual manifestation of extrapulmonary tuberculosis, especially in immunocompetent hosts. It often poses diagnostic difficulties as microbiological confirmation is not easy. In this case report, we describe a case of pseudocyst of the spleen due to tuberculosis, which is a rare clinical presentation with only one case having been reported previously. A 24-year-old immunocompetent woman presented with pain in the abdomen, vomiting and fever. On evaluation the patient was found to have a cyst arising from the spleen. Splenectomy was performed. Pathological examination of the specimen revealed a pseudocyst with granulomas and giant cells consistent with tuberculosis. Cyst fluid analysis revealed lymphocyte predominance with high adenosine deaminase levels. The patient was started on 6 months of antituberculous therapy postoperatively. On follow-up, the patient was found to have gained weight and showed signs of well-being.
