Disseminated tuberculosis in elderly patients. A report on three cases diagnosed intra vitam.

Abstract. Three elderly patients admitted to hospital because of suspected malignancy have been diagnosed as disseminated tuberculosis during life. Classical features of disseminated tuberculosis such as miliary mottlings on the chest roentgenogram and choroidal tuberculosis were absent in two of the patients. The difficulties hindering the establishment of the diagnosis of “cryptic” disseminated tuberculosis are emphasized by the patient records. Response to treatment with isoniazide and para-amino-salicylic acid is in some cases the only evidence of tuberculosis. Moreover, the early institution of such therapy when other evidence of tuberculosis is lacking may cure the disease before it enters an irreversible state, and is strongly recommended.
