Introduction: Cervical lymph node metastases from differentiated thyroid carcinomas occur mainly in the central compartment with an incidence between 20 and 90% (average 60%). The American Thyroid Association considers that the central compartment goes to the unnamed artery thus systematically including level VII to level VI. We report the case of a patient with resected level VII lymph thanks to identification by technetium99-nanocolloid.
Observation: Patient 32-year-old followed for 3 years for papillary thyroid carcinoma initially classified PT2N1bM0 who received an iratherapy treatment with a thyroglobulin (Tg) level at 71.86 ng/ml and post-therapeutic scanning: hyperfication cervical lymphadenopathy. At 3 months post-iratherapy in front of a Tg at 8.10 ng/ml, a cervical ultrasound finds a lymphadenopathy in level VII, whose fine needle biopsy returned carcinomatous with Tg in rinsing liquid highly positive. The TEP-FDG finds this lymphadenopathy without remote localization. The patient is reoperated under detection by iodine 131, unfortunately the lymphadenopathy doesn’t fix the iodine, it couldn’t be resected. In view of the Tg levels remained high, it was reoperated a third time under detection with in situ injection of technetium99-nanocolloid, the anatomopathological study found 2 lymphe node metastasis infiltrated and the postoperative ultrasound returned without abnormality.
Discussion: The resection of a lymph node metastasis of a thyroid papillary carcinoma by technique of in-situ injection of technetium99-nanocolloid, inspired by the technique of the sentinel node seems to be a new technique which would make it possible to act on lymphe node difficult to access on a neck modified by previous surgery and which no longer fixes iodine.
