Abstract:
Computed tomographic findings of 24 cases of cervical tuberculous lymphadenitis were retrospectively analyzed. We classified the CT findings as 4 types: type 1(homogeneous soft tissue density mass), type 2(central low density with peripheral rim enhancement and with preservation of surrounding fat plane), type 3(central low density with peripheral rim enhancement and with obliteration of surrounding fat plane), type 4(large confluent low density mass, so called "cold abscess") As a result, there were 2 cases(8.3%) of type 1, 7 cases(29.2%) of type 2, 9 cases(37.5%) of type 3, 3 cases(12.5%) of type 4, 1 cases(4.2%) of type 1 combined with type 3, and 2 cases(8.3%) of type 2 combined with type 4. So 22 cases(91.7%) revealed central low density and peripheral rim enhancement, which suggest necrosis. The maximum thickness of enhancing rim was above 2mm in all of 64 definable necrotic lymph nodes and above 4mm in 42(65.5%) lymph nodes, suggesting that the wall of necrotic tuberculous lymphadenitis tends to be thick. We conclude that CT is useful not only for the diagnosis but also for the evaluation of the extent and the status of cervical tuberculous lymphadenitis.
