[Differential diagnosis of neck tumors by angiography (author's transl)]
Abstract:
Angiographic criteria and differential dignosis of tumors of the lateral neck are demonstrated in 200 examined patients. There is a typical angiographic pattern in chemodectomas. Extreme vascularization and localization in the area of the carotid bifurcation are characteristic for these tumors. Neurinomas are avascular or minimally vascularized. The character of carotid artery deviation allows to distinguish neurinomas from other neoplasms of the neck. Metastases of thyroidal carcinoma are usually represented by pronounced vascularized tumors with a smooth border. Metastases of squamous cell carcinomas as primary mesenchymal tumors are minimally vascularized or sometimes avascular. There is increased vascularization in combination with perifocal inflammation. It is impossible to differentiate metastases of squamous cell carcinomas from primary mesenchymal tumors by angiography.
