We studied eight patients with miliary tuberculosis (TB). In all insta
nces, tuberculomatous lesions were demonstrated in the aspirated bone
marrow. We conclude that the bone marrow aspiration has great value in
diagnosing miliary TB because it provides sufficient material to perm
it examination of serial sections as needed to confirm the diagnosis.
The bone marrow aspiration also is safer than the alternative procedur
es of lung or liver biopsies.
