A Killian-Jamieson diverticulum potentially mimicking a thyroid nodule: A case report highlighting the cytology of a pharyngoesophageal diverticulum Fine-needle aspiration of a pharyngoesophageal diverticulum mimicking a calcified thyroid nodule on ultrasonography. Details of oesophageal content on fine needle aspiration biopsy (FNAB) of the thyroid to discern PED from thyroid nodules have been described in reports.[[1], [3], [5], [7]] Although radiological imaging is needed to differentiate diverticula from thyroid nodules, FNAB has been shown to be a useful initial test to evaluate and diagnose pretenders of thyroidal lesions.
