Mirror image artifact in ultrasound is not an unusual phenomenon. However, it is rarely seen in thyroid ultrasound because of the natural convexity of the tracheal surface. We report a mirror artifact during thyroid ultrasound in a patient with an excessively collapsible trachea. Minor pressure with the transducer made the trachea surface flat or concave, and then a cyst in the thyroid was mirrored across the trachea, which mimicked an intratracheal cyst. This case illustrates how an unusual collapsible trachea can generate an image that simulates an intratracheal lesion during thyroid ultrasound...

Differentiation of benign and malignant thyroid nodules is crucial for clinical management. Here, we explored the efficacy of next‑generation sequencing (NGS) in predicting the classification of benign and malignant thyroid nodules and lymph node metastasis status, and simultaneously compared the results with ultrasound (US). Thyroline was designed to detect 15 target gene mutations and 2 fusions in 98 formalin‑fixed, paraffin‑embedded (FFPE) tissues, including those from 82 thyroid cancer (TC) patients and 16 patients with benign nodules...

BACKGROUND: Thyroglobulin antibodies (TgAb) can interfere with Tg measurement and can be used as "Tg surrogate" in patients with differentiated thyroid cancer (DTC) treated with total thyroidectomy (TTx) plus radioiodine remnant ablation (RRA). At variance, few data, and in patients usually followed for a short term follow-up, have been reported about the changes of TgAb levels in patients treated with TTx but not RRA. The aim of this study was to evaluate the changes of TgAb levels in DTC patients treated with TTx but not RRA and to identify the factors that influence these changes...

In this study, we aimed to evaluate dosimetric approaches in ablation treatment of Differentiated Thyroid Carcinoma (DTC) without interrupting the clinical routine. Prior to therapy, 10.7 MBq 131 I in average was orally given to 24 patients suffering from DTC. MIRD formalism was used for dosimetric calculations. For blood and bone marrow dosimetry, blood samples and whole-body counts were collected at 2, 24, 72, and 120 h after I-131 administration. For remnant tissue dosimetry, uptake measurements were performed at the same time intervals...

Papillary thyroid cancer (PTC) can present as a thyroid cyst. In its more aggressive form, PTC may be multifocal in nature and is associated with a poorer prognosis. In patients whom PTC is diagnosed incidentally after a diagnostic lobectomy, the decision whether to offer completion thyroidectomy is sometimes challenging to make if such patients fall in the 'low-to-intermediate' risk category. We present a case of a 55-year-old lady who had a predominantly cystic left thyroid nodule with no suspicious features on ultrasound as well as 2 subcentimetre simple right-sided cysts...

BACKGROUND: The 2015 American Thyroid Association (ATA) guidelines recommend using a classification based on sonographic patterns to set the size-threshold for biopsies. Each pattern is associated with a distinct estimated rate of malignancy that, we hypothesize, should stratify the risk of malignancy of cytologically indeterminate thyroid nodules. METHODS: Ultrasound images of 463 indeterminate thyroid nodules (38% atypia/follicular lesions of undetermined significance; 62% follicular neoplasms) with histological follow-up consecutively evaluated between 10/2008 and 06/2015 at our academic cancer center were independently evaluated by 3 observers and classified into one of the five sonographic patterns proposed by the ATA...

BACKGROUND: Low-risk patients with differentiated thyroid cancer can be treated with thyroid lobectomy. Serial measurements of serum thyroglobulin (Tg) are recommended for surveillance, but the cut-off values indicating recurrence are not known. We documented the natural course of serum Tg levels during follow-up after lobectomy for low-risk papillary thyroid carcinoma (PTC), and evaluated whether changes in serum Tg levels predict disease recurrence. METHODS: This historical cohort study included 208 patients with low-risk PTC who underwent lobectomy but did not require hormone replacement...

BACKGROUND: Papillary thyroid cancer (PTC) is an uncommon pediatric disease with an excellent prognosis. In follow-up surveillance, neck ultrasound (US), basal and thyroid-stimulating hormone-stimulated serum thyroglobulin (Tg) levels, and diagnostic whole-body radioactive iodine scans (DxWBS) have been traditionally used in both adults and children for the detection of recurrence or metastases of PTC. METHODS: Two pediatric patients with metastatic PTC were followed after standard ablative treatment with routine neck US and serum Tg levels, as well as periodic DxWBS...

Sir, Thyroid tumors occur rarely as associated to nervous system diseases. We had recently studied a case of thyroid carcinoma, peculiar by the predominant eosinophilic/oncocytic/oxyphil/Hurthle cell-component associated to multiple sclerosis (MS). The patient (man, 31-years old) presented with hair loss, diarrhea, thermophobia, tremor and tachycardia. The medical history revealed allergy (pollen, prawn), recurrent uveitis and optic nevritis (at the age of 12-years). A Behcet disease was suspected. Corticoid treatment was given for more than 6 years...

OBJECTIVES: This study was designed to confirm the echogenicity of normal parathyroid glands using intraoperative ultrasound (US). METHODS: Between October 2015 and January 2016, normal parathyroid glands were examined with an intraoperative US transducer during thyroidectomy procedures in 13 patients with thyroid disease. According to the findings from intraoperative US, routine percutaneous US of normal parathyroid glands was performed in a group of adults. On the basis of previous information on normal parathyroid echogenicity, a series of parathyroid diseases that were proved by surgery and histopathologic analyses were retrospectively reviewed...

PURPOSE: Ultrasonographic characteristics of thyroid nodules play an important role in estimating the risk of malignancy (ROM). Guidelines mandate all thyroid nodules be characterized by six key ultrasonographic features to estimate the ROM. Our objective was to evaluate how frequently these characteristics were identified by radiologists and the ensuing utility to estimate ROM. METHODS: We retrospectively reviewed 1930 consecutive diagnostic thyroid ultrasound reports from a large community radiology practice...

This study was conducted to evaluate the role in the differential diagnosis of thyroid nodules of various elastographic and Doppler parameters when added to gray-scale ultrasonography (US). One-hundred seventy-one thyroid nodules (63 malignant, 108 benign) in 169 patients were included. Elastography (strain and shear wave elastography) and Doppler (power Doppler, superb microvascular imaging and microflow imaging) images of the same thyroid nodule were obtained using a single US machine. The diagnostic performance parameters of gray-scale US with and without elastography and those of Doppler US were calculated and compared...
