Contrast-Enhanced Ultrasound of Anaplastic Thyroid Cancer: A Case Report and Review of the Literature

A 54-year-old female patient, a breast cancer survivor and a case of unresectable adenoid cystic carcinoma of the trachea, with thyroid invasion, presented with suprasternal neck swelling mimicking thyroid primary. A literature search was undertaken to highlight this rare presentation. There have been few reports in the literature describing tracheal adenoid cystic carcinoma involving the thyroid.

Ultrasound Features

Duodenal neuroendocrine tumors are rare neoplasms arising from endocrine cells. Here we present a case of 32-year-old woman with Duodenal neuroendocrine tumors, report the imaging and contrast-enhanced Ultrasound (CEUS) features and review previous literatures of neuroendocrine tumors, which may be valuable for the differential diagnosis of duodenal neoplasms.

We report the case of a 56-year-old postmenopausal woman whopresented with incidental left hydronephrosis during an investigationfor a gastrointestinal complaint. The patient denied any historyof flank pain or hematuria. Contrast-enhanced computedtomography revealed severe right-sided ureterohydronephrosis aswell as renal atrophy. The contralateral kidney was normal, as wasthe patient’s overall renal function. A retrograde ureterogramdemonstrated complete ureteral obstruction 4 cm proximal to theureterovesical junction. Subsequent ureteroscopy revealed a polypoidmass completely occupying the ureteral lumen, of which thebiopsies demonstrated inconclusive atypical urothelial changes.The patient underwent a laparoscopic nephrectomy with opendissection of the distal ureter. The patient recovered well postoperatively.Final pathology revealed a benign obstructingendometrioma without evidence of invasion from periureteraltissue. This appears to be the first reported case of asymptomaticprimary ureteral endometrioma with secondary renal atrophy.Earlier investigation and treatment may have allowed for renalpreservation earlier in the course of the disease.Nous décrivons le cas d’une femme ménopausée de 56 ans présentantune hydronéphrose gauche découverte de façon fortuite aucours d’un examen mené pour donner suite à des symptômes gastro-intestinaux. La patiente n’avait pas d’antécédents de douleurau flanc ou d’hématurie. Une TDM avec agent de contraste arévélé une urétéro-hydronéphrose droite importante accompagnéed’une atrophie rénale. Le rein controlatéral et la fonction rénaleglobale de la patiente ne présentaient aucune anomalie. Uneurétérographie par voie rétrograde a permis d’observer une obstructioncomplète de l’uretère proximale à 4 cm de la jonction urétérovésicale.Une urétéroscopie subséquente a révélé une masse polypoïdeoccupant la totalité de la lumière urétérale et des analysesaprès biopsie ont montré des changements atypiques non concluantsau niveau de l’épithélium urinaire. La patiente a subi unenéphrectomie par laparoscopie avec dissection ouverte de l’uretèredistale. La patiente s’est bien rétablie après l’intervention. Lerapport final de pathologie a révélé un endométriome obstructifbénin sans signe d’invasion des tissus péri-urétéraux. Il sembleque ce soit ici le premier cas signalé d’endométriome urétéralprimitif asymptomatique avec atrophie rénale secondaire. Un examenet un traitement réalisés plus tôt dans le cours de l’évolutionde la maladie auraient pu permettre la préservation du rein.
