Video-Assisted Thoracoscopic Resection of Cervicomediastinal Masses Using Preoperative Virtual 3-Dimensional Imaging

This case report describes a 59-year-old woman with a residual cervicomediastinal thyroid mass after right thyroid lobectomy for papillary carcinoma. Because of its deep intrathoracic extension and proximity to major vessels, a purely cervical approach was not feasible. The operation was planned using high-resolution, contrast-enhanced computed tomography and preoperative 3-dimensional reconstruction to delineate vascular and anatomic relationships. Video-assisted thoracoscopic surgery enabled complete resection with uneventful recovery. This case highlights how 3-dimensional imaging can enhance surgical planning, precision, and safety in complex mediastinal procedures.
