41 cases of intraparotid lymph node tuberculosis and 51 cases of parotid tumors were studied. The authors suggest the following points for differential diagnosis: Clinically, intraparotid lymph node tuberculosis has a rapid onset, pustulation, regional lymphade nopathy, with a history of TB or contact with tuberculosis and low-grade fever. In most cases, the nerves function normal. Sialograms show no signs of branch ducts twist and irregular stricture and dilation. The diameter of exudative contrast mass could be more than 1 cm, but it does not exudate along the ducts. The posterior margin of ascending ramus does not show deformity. Calcification of cervical lymph nodes could be seen. If the tuberculosis mass is small, it is hard to be distinguished from tumor on sialograms. The clinical features are important in the diagnosis.
对41例腮腺内淋巴结结核和51例腮腺肿瘤进行了研究。作者提出以下鉴别诊断要点：临床上，腮腺内淋巴结结核起病急，有脓疱形成，区域淋巴结肿大，有结核病史或接触史，低热。多数情况下神经功能正常。腮腺造影显示无分支导管扭曲及不规则狭窄和扩张。渗出性造影剂肿块直径可超过1cm，但不沿导管渗出。升支后缘无畸形。可见颈部淋巴结钙化。如果结核肿块较小，在腮腺造影上很难与肿瘤区分。临床特征对诊断很重要。
