Comparison of 99mTc-Tilmanocept and Hybrid Indocyanine Green-99mTc-Albumin Nanocolloid Drainage in a Patient With Melanoma in the Scalp.

Comparison of 99mTc-Tilmanocept and Hybrid Indocyanine Green-99mTc-Albumin Nanocolloid Drainage in a Patient With Melanoma in the Scalp.

Publication date: Oct 07, 2020

We present the planar lymphoscintigraphies and SPECT/CT images of a 60-year-old man diagnosed as having melanoma (Breslow 1.8 mm) in left parietal scalp, close to head midline. Sentinel lymph node biopsy using Tc-tilmanocept was performed, but the surgery was canceled. Two weeks later, sentinel lymph node biopsy was repeated, but using the hybrid radiotracer indocyanine green-Tc-albumin nanocolloid. The lymphatic drainage in left laterocervical region was similar with these 2 radiotracers, but on the right side, more sentinel lymph nodes were detected with nanocolloid compared with tilmanocept.
