False-positive finding on 18F-FDG PET after chemotherapy for primary diffuse large B-cell lymphoma of the thyroid: A case report
No full textPrimary non-Hodgkin lymphoma of the thyroid is an uncommon disease. It is a potentially aggressive disease and diffuse large B-cell lymphoma of the thyroid may result in 5 year survival rates <50%. Hence adequate follow-up and multimodality treatment for recurrent or persistent disease are required. Since 18F-FDG PET is considered the imaging method of choice for the detection and staging of lymphoma, this was used for restaging of a case of diffuse large B-cell lymphoma of the thyroid after chemotherapy and its diagnostic value is questioned in the present case report. In fact, PET showed a false-positive finding which led to unnecessary surgery

Ectopic Intrathyroidal Thymus in Children: A Long-Term Follow-Up Study
No full textBackground: Ectopic intrathyroidal thymus has recently been reported in children as a cause of surgery and/or invasive diagnostic procedures when mistaken for a thyroid nodule. Thymus has a unique appearance at ultrasound (US). Methods: We report a follow-up study (mean 34 months, range 6-84) performed by US on 9 children (5 females) with a mean age of 6.3 +/- 3.2 years with intrathyroidal thymic inclusions diagnosed by US as 'incidentalomas'. None has palpable nodules. Results: Intrathyroidal thymic inclusions appeared on US as a hypoechoic area, with regular linear or punctuate internal hyperechoic echoes. The 2 oldest patients (13 and 17 years) showed a regression in both size and hypoechogenicity of thymic inclusions over time - reflecting the normal thymic involution with advancing age. Conclusions: Indeed, the lack of progression seen in our 9 patients over a mean time of 34 months confirmed the substantially benign and self-limited nature of this process. The increasing use of thyroid ultrasonography in children may result in an increased detection of intrathyroidal thymic inclusions - an embryologic anomaly that should be considered in the differential diagnosis of thyroid nodules in children and adolescents.

Incidental parathyroid adenomas with normocalcemia discovered during thyroid operations: Report of three cases
No full textWe report three cases of parathyroid adenoma incidentally discovered during a total thyroidectomy. No patients showed any clinical or chemical features that led us to suspect a hyperparathyroidism condition before operation, but a macroscopically enlarged parathyroid was discovered during the dissection and it was removed in all three cases. All patients had a single adenoma confirmed by a histological analysis. Calcemia decreased after operation in every case but only one patient needed temporary adjunctive therapy. No permanent hypoparathyroidism or recurrent hyperparathyroidism was observed. We recommend that any enlarged parathyroid discovered during neck surgery should thus be removed in order to avoid the risks of future surgical procedures due to successive bouts of clinical hyperparathyroidism
