# Whispers in the Neck: Unmasking Cystic Metastases From Hidden Papillary Thyroid Carcinoma

## TL;DR

A young woman with a seemingly benign neck cyst was found to have hidden thyroid cancer that had spread to the lymph nodes.

## Contribution

This case highlights the potential for occult papillary thyroid carcinoma to present as a cystic neck mass.

## Key findings

- A benign-appearing cystic neck mass was diagnosed as metastatic papillary thyroid carcinoma.
- The patient underwent completion thyroidectomy and neck dissection following the diagnosis.

## Abstract

Papillary thyroid carcinoma is the most common thyroid malignancy and it frequently causes lymph node metastases. Approximately 50% of patients with papillary thyroid carcinoma have cervical lymph node metastases at the time of their initial presentation. Here we report a case of a young female who presented with a benign-appearing cystic neck mass, which was revealed to be metastases from occult papillary thyroid carcinoma. Completion thyroidectomy and neck dissection were done after the diagnosis of papillary thyroid carcinoma.
