Primary splenic tuberculosis in a patient with nasal angiocentric lymphoma: mimicking metastatic tumor on abdominal CT.
Tuberculosis may be difficult to diagnose when it presents in an uncommon extrapulmonary site. The authors report a case of splenic tuberculosis mimicking metastatic tumor on computed tomography in a 60-year-old woman who had been treated with combination chemotherapy for nasal angiocentric lymphoma. Diagnostic splenectomy revealed multiple necrotic masses in the spleen, which were consistent with caseating granulomas microscopically. Diagnosis was confirmed by positive cultures in Lowenstein medium, which grew typical Mycobacterium tuberculosis organisms. Following splenectomy, the patient was also treated with a triple-drug antituberculosis regimen with no recurrence of her symptoms.
