Ultrasonographic findings of thyroglossal duct papillary carcinoma: A case report

Abstract

HighlightsThyroglossal duct cyst carcinoma can be classified as primary, secondary and multicentric.Preoperative ultrasound with possible fine needle aspiration biopsy are useful for determining the extent of the operation.The treatment is Sistrunk’s operation with the addition of total thyroidectomy and neck dissection when indicated.

Two separate tumours—Concomitant papillary carcinoma in thyroglossal duct cyst and right thyroid lobe: Case report and review of the literature

“…CT of the neck is not standard at our institution for uncomplicated cases, and is undertaken in suspected cases as mentioned above. This is in line with the literature, as Table 1 shows that within the published cases, US scan was undertaken for 4 out of the 5 cases including the current case [ 13 , 14 , 18 ], while CT of the neck was done in a minority (2 out of 5) of cases [ 14 , 19 ]. FNAC or core needle biopsy are safe, well-tolerated, and cost-effective for diagnosing thyroglossal duct lesions and are recommended [ 11 ].…”

“…Table 1 shows that the current patient was the youngest in the reported cases of concomitant TGDC carcinoma and thyroid carcinoma. The female gender of our patient also supports the fact that more females are affected with TGDC carcinoma than males [ 10 ], and our review ( Table 1 ) illustrates that concomitant papillary carcinoma in TGDC and in the thyroid could be twice more likely among females than males [ 13 , 14 ]. In addition, our patient was from the Philippines, where Filipinos are known to have higher prevalence of thyroid cancers that display more aggressive behaviour [ 15 ].…”

“…Some surgeons recommend that total thyroidectomy should be performed in all cases of TGDC carcinoma [ 7 ], because of the high incidence of the presence of concomitant thyroid malignancy in the main thyroid gland as a pathophysiology; or to facilitate radioactive iodine therapy and adjuvant treatment therapy [ 2 ]. Table 1 shows a case treated by Sistrunk’s operation as the primary surgery, and then after the histopathology results, the patient underwent secondary total thyroidectomy [ 13 ], compared with the rest of the cases in Table 1 that underwent total thyroidectomy in addition with compartmental dissection [ 14 , 18 , 19 ]. In our patient, despite her low risk (young patient, no past medical illnesses, no family history), a high measure of care was taken (Sistrunk's operation and total thyroidectomy undertaken together) because of the potential high risk of thyroid malignancy among individuals from the Philippines [ 15 ], and the possibility of carcinoma arising in the identified thyroid nodule.…”

Thyroglossal Duct Cyst Papillary Carcinoma: A Case Report and Review of the Literature

“…In addition to its advantages of being simple, fast, inexpensive and free of radiation, ultrasound can also guide clinical work, like performing the differential diagnosis of neck masses, checking suspicious characters of any malignancy in the mass and guiding FNAB. In general, uncomplicated thyroglossal duct cysts may show as anechoic and well circumscribed on ultrasound, while malignancy will be suspected in the presence of cystic with solid component, septation, mural mass with punctate calcifications and cervical lymphadenopathy [7,8]. Therefore, when the patient has these suspicious signs, further examination is required, such as FNAB.…”

Thyroglossal duct cyst papillary carcinoma with lymphatic infiltration: A case report

“…8 Additionally, abnormal cervical lymph nodes are often visible. 8 On contrast-enhanced neck computed tomography, the lesion may appear as a solid mass with calcification or as a unilocular or multilocular cyst with solid component. 9,10 The magnetic resonance imaging of TDCC is rarely reported but typically depicts high-intensity cyst components and the heterogeneous solid component on T2-weighted images.…”
