Abstract
Lymph node Imaging has been helpful In managing patients with lymphoma, melanoma, and breast cancer. To evaluate 38 patients with head and neck cancers, 99mTC minicolloid was injected adjacent to the tumor and into a similar area on the uninvolved side. Lymphoscintigraphy of the neck was performed at 3‐ and 5‐hour intervals after injection and bilateral cervical lymphatic drainage was observed. Each patient then underwent a neck dissection. The pathologic node findings were then correlated with the neck scans. Results confirmed that cervical lymphatic drainage is unpredictable in 50% of the patients once the channels are involved with metastatic disease. Lymphoscintigraphy is not a reliable method of detecting early metastatic cervical carcinoma.
