Abstract
Background Extrapulmonary tuberculosis (EPTB) is known to have many and varied presentations.
However, isolated involvement of bone with tubercular infection is uncommon. The clinical
features of such infections are known to mimic chronic pyogenic osteomyelitis, Brodie
abscess, or tumors, but not acute monoarthritis.
Case Description We describe here an unusual case of tuberculous osteomyelitis that mimicked features
of acute monoarthritis of the wrist joint.
Literature Review Extraspinal tuberculous osteomyelitis is rare and comprises only about 2 to 3% of
all cases of osteoarticular tuberculosis, with the hip and knee joints being the most
commonly involved. An extensive literature review did not show any published report
of tuberculous osteomyelitis presenting as acute monoarthritis of the wrist joint.
Clinical Relevance This case underlines the importance of making EPTB an important differential diagnosis
even in cases with clinical features that are completely inconsistent with tubercular
infections.
