Thyroid No Surgery 101: Post Ethanol Ablation PEI Ultrasound Patterns for Thyroid Cysts: Some Mimic Cancer Changes.
Comments on this Study by DR.G.by Noh Hyuck Park et al
2. 40 patients with thyroid cysts (n = 14) and predominantly cystic thyroid nodules (n = 26) underwent long-term US follow-up (range, 12–36 months; mean, 18.2 months) after PEI.
3.US images of 40 post-PEI nodules were retrospectively investigated to study the reduction in nodule volume and detailed US appearance.
4. Ultrasound features post PEI were Marked hypoechogenicity (n = 28), spiculated margin (n = 7), microcalcifications (n = 6), taller-than-wide shape (n = 2),
centrally predominant vascularity (n = 3), no vascularity (n = 31), mixed vascularity (n = 3), and peripheral vascularity (n = 3).
4. Post-PEI nodules were diagnosed by US as benign (n = 3), probably benign (n = 2), borderline (n = 5), possibly malignant (n = 20), and malignant (n = 10).
5. A high incidence of findings that are usually associated with malignancy.
6. Recognizing these consequences of the procedure would help avoid unnecessary FNA on post-PEI nodules.
If you have a patient post PEI for a thyroid cyst remeber that the ultrsound can look like suspicious or definite cancer.These are just changes secondary to the PEI treatment and do not need a biopsy or surgery.
