We reviewed the pattern of involvement of the calvarium by tuberculosis (TB
) in five patients and the role of imaging in its management. Four patients
presented with localised scalp swelling and one with generalized seizures.
Radiographs revealed lucent lesions with minimal surrounding sclerosis in
the frontal (2), parietal (2) and occipital (1) bones. CT showed lesions in
volving the entire thickness of the calvarium and accompanying contrast-enh
ancing soft tissue. The patient presenting with seizures had a ring-enhanci
ng lesion in the parietal lobe in addition to the extra-axial lesions. Alth
ough radiographs in all cases demonstrated calvarial TB, CT showed the exte
nt of the defect, involvement of adjacent soft tissues, and in one case an
intra-axial lesion. Radiographs suffice for follow-up of these patients.
