CT diagnosis and staging of adrenal tuberculosis / 中华放射学杂志

ABSTRACT

Objective To evaluate correlation of CT features of tuberculous adrenal glands with duration of adrenal insufficiency and propose a new staging criteria for adrenal TB Methods CT features of 28 cases of documented adrenal tuberculosis were analysed retrospectively The patients were divided into 3 groups according to the duration of adrenal insufficiency group A (10 cases , less than 1 year), group B (13 cases, 1 year to 4 years), group C (5 cases, longer than 4 years) The main CT features analyzed included size and shape of the adrenal gland, calcification ,and low density foci Results Enlargement of the adrenal gland group A(10) , group B (13), group C (1) Basic configuration of adrenal gland were identifiable in group A ,whereas others had more irregular shape Calcification group A (2) , group B (11),group C (5) Low density foci group A (3), group B(0), group C (0) Conclusion CT features of adrenal glands correlated with duration of adrenal insufficiency in adrenal tuberculosis It is more reasonable to use tri phase criteria according to CT appearance in adrenal tuberculosis
