OBJECTIVE To assess the role of high-resolution ultrasonography in the preoperative evaluation of patients with hyperparathyroidism. DESIGN Retrospective cohort. SETTING Tertiary care university hospital. PATIENTS Three hundred seventeen patients with hyperparathyroidism who underwent preoperative assessment with ultrasonography and/or sestamibi scan and surgical treatment between October...

Background. Cervical recurrence occurs in up to 30% of patients with differentiated thyroid carcinoma. We retrospectively compared preoperative transcutaneous ultrasonography and physical examination (PE) results in the detection of local-regional metastases (lymph node and soft tissue) in patients with thyroid cancer. Methods. Data were collected retrospectively from the medical records of pat...

Ultrasonography is pivotal in triage thyroid biopsy in the era after the identification of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This pictorial essay illustrates the pathologic basis of the sonographic features that distinguish NIFTP from thyroid cancers. In this study, we present the correlations of ultrasonography to ×1 histopathology to assess ...

A 68-year-old man was diagnosed as having advanced gastric cancer. Computed tomography showed a thyroid tumor with trachea deviation. This tumor exhibited mosaic echogenecity in ultrasonography. Signet-ring cell carcinoma was found by means of fine needle aspiration biopsy. This tumor gradually became swollen and the thyroid hormone levels in blood were increased without any clinical symptom. S...

thyroid hemiagenesis can be associated with various thyroid pathologies such as papillary thyroid cancer or nodular goiter. however, we did not encounter any publication in the literature in which hemiagenesis could be observed together with retrosternal goiter. in this report, a thyroid hemiagenesis associated with a benign nodular goiter extending retrosternally is reported. a 59-year-old mal...

OBJECTIVE The clinical management of patients with thyroid nodules that are biopsied by fine-needle aspiration cytology and yield indeterminate results remains unsettled. The BRAF V600E mutation has dubious diagnostic value due to its low sensitivity. Novel strategies are urgently needed to distinguish thyroid malignancies from thyroid nodules. DESIGN This prospective study included 504 thyro...

introduction: a thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance. palpable thyroid nodules occur in 4 to 7 percent of the population. nodular thyroid diseases are more frequent in women than in men. most actions of thyroid hormone are mediated by the active form of thyroid hormone. d2 is essential for formation of active hormone of t3 through deiodina...

A diffuse sclerosing variant of papillary thyroid carcinoma is uncommon and has a tendency for rapid growth and a higher incidence of cervical lymph node metastases. We experienced a case of a diffuse sclerosing variant of papillary thyroid carcinoma in a 48-year-old man. This case showed benign features on initial ultrasonography and positron emission tomography (PET) scan. A new nodule was de...
