Introduction:
Excision of cervical lymph nodes in children can be technically demanding when nodes are small or deeply located. Combining ultrasound-guided tracer injection with an intraoperative portable gamma camera allows functional guidance during surgery.
Case Report:
A pediatric patient with persistent unilateral cervical lymphadenopathy underwent ultrasound-guided injection of a technetium 99mTc-labeled tracer. In the operating room, the portable gamma camera identified focal uptake and guided a targeted nodal excision through a limited cervical approach. The specimen was obtained safely, the procedure was uneventful, and recovery was rapid.
Discussion:
The use of ultrasound-guided tracer deposition combined with an intraoperative portable gamma camera provided precise, real-time navigation for pediatric lymph node excision. This approach may help reduce the extent of dissection and operative time while maintaining safety. It represents a feasible adjunct for selected pediatric cervical procedures.
