Ultrasound is the recommended diagnostic modality used to diagnose cervical ectopic thymus. [6] The thymus has a unique appearance on ultrasound, which allows for specific diagnosis. [7] [8] Ectopic thymus appears hypoechoic, with characteristic linear echogenic foci. [3]
A 51-year-old female patient post total thyroidectomy for PTC with elevated thyroglobulin measurement. an Axial non-enhanced CT scan of the neck at the level of the thyroid bed demonstrates a well-defined, rounded, homogenously dense soft tissue situated between the trachea and left internal jugular vein (white arrow). b Transverse ultrasound ...
In this study, ultrasound was only 35% accurate at finding a single loop, and only 60% accurate at detecting a nuchal cord wrapped multiple times around the neck. [9] In no study was it possible by ultrasound to distinguish between a loose or a tight cord, although at least 3 attempted to do so.
The indications to do FNAC are: nodules more than 1 cm with two ultrasound criteria suggestive of malignancy, nodules of any size with extracapsular extension or lymph nodes enlargement with unknown source, any sizes of nodules with history of head and neck radiation, family history of thyroid carcinoma in two or more first degree relatives ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
In cervical lymphadenopathy (of the neck), it is routine to perform a throat examination including the use of a mirror and an endoscope. [27] On ultrasound, B-mode imaging depicts lymph node morphology, whilst power Doppler can assess the vascular pattern. [28]
In another study values of 79.6% and 2.7% for the combined screening were then improved with the addition of second trimester ultrasound scanning to 89.7% and 4.2% respectively. [13] A further study reported detection of 88% for trisomy 21 (Down syndrome) and 75% for trisomy 18 (Edwards syndrome), with a 3.3% false-positive rate. [14]
Other clinical signs that could indicate papillary thyroid are fixation to the trachea, a firm neck mass, damage to recurrent laryngeal or cervical sympathetic nerves. Five percent of the population can have thyroid nodules, and the majority will be benign. [6] Appropriate workup includes an ultrasound of the neck, followed by lab studies.
