Abstract:
Objective To evaluate the contrast enhanced CT manifestations of lymphoma involving cervical lymph node and to compare with features of metastatic squamous cell carcinoma. Methods CT findings of cervical lymph node were reviewed in 56 patients (male 44, female 12; age: 9-75 year, median 42 year) with untreated lymphoma and 66 patients (male 51, female 15; age: 16-76 year, median 48 year) with squamous cell carcinoma. Four patterns of enhanced nodes were identified: Type I: homogeneous enhancement with an attenuation equal or similar to that of muscle. Type Ⅱ: heterogeneous enhancement with an attenuation much higher than that of muscle. Type Ⅲ: central low density with peripheral enhancement. The enhanced rim was thick and irregular (ⅢA), or thin and regular (ⅢB). Type Ⅳ: central soft tissue density with a very thin enhanced capsule. Results There were various manifestations of cervical nodes of malignant lymphoma, more than one type of abnormalities could be found simultaneously. Type I(47/56, 83.9%) and Type Ⅳ(15/56, 26 8%) were almost exclusively found in lymphoma. Type Ⅱ was more commonly seen in squamous cell carcinoma (31/66, 47%), but was rarely seen in lymphoma (8/56, 14 3%). Type Ⅲ can be seen in both of these disease entities (lymphoma 21/56, 37 5%; squamous cell carcinoma 52/66, 78 8%) , but was more common in squamous cell carcinoma ( P
