“…The echogenicity of accessory thyroid nodules or ectopic thyroid tissues, which exhibit vascular flow, is the same as that of the thyroid 27 . Carotid body paragangliomas are well-defined, solid, hypoechoic masses at a characteristic location, straddling the carotid bifurcation and splaying the internal and external carotid arteries 28 . Nerve sheath tumors are heterogeneously hypoechoic and often demonstrate posterior acoustic enhancement 5 .…”

“…Nerve sheath tumors are heterogeneously hypoechoic and often demonstrate posterior acoustic enhancement 5 . They are fusiform or ovoid with tapering ends, and continuity with adjacent nerves is a diagnostic feature 28 . Venous vascular malformations appear as soft, compressible, heterogeneous, hypoechoic masses 29 .…”

“…No significant vascularity is present, and their characteristics are similar to those of ETT. However, the presence of multiple thin echogenic lines parallel to the transducer, resulting in a “feathered” or “striped” appearance, is characteristic 28 . Thus, we believe that it is not difficult to distinguish phantom nodules from the other small nodules located in the perithyroidal region.…”

PurposeThe aim of this study was to investigate the ultrasound characteristics and clinical significance of slightly hyperechoic lesions, referred to as phantom nodules, in the perithyroidal area in patients.Materials and MethodsA total of 128 patients who underwent thyroidectomy with central neck lymph node dissection at Kuma Hospital in Hyogo, Japan were included in the study. We detected 16 phantom nodules during preoperative ultrasound examinations, defined as slightly hyperechoic masses located in the perithyroidal areas, in 13 of these 128 patients (10.2%; mean age: 55.6 years, range: 36–75 years).ResultsAll phantom nodules were located in the caudal region of the thyroid gland, and the mean maximum dimension was 7.2 mm. 12 of the 16 nodules were round or oval, while the remaining 4 were fusiform and molded by the surrounding tissue. All nodules were well-defined, solid, homogeneous, hyperechoic masses. No speckled echo pattern, internal linear echo, or vascular flow signal was observed. All 4 nodules subjected to histological examination were composed of ectopic thymic tissue. In 2 of these 4, the parenchyma was severely involuted and almost entirely replaced by adipose tissue.ConclusionTo the best of our knowledge, this is the first report wherein some of the detected hyperechoic perithyroidal masses were composed of ectopic thymic tissue, and some were primarily composed of adipose tissue that completely replaced involuted ectopic thymic tissue. The results of the study suggest that these so-called phantom nodules are clinically insignificant and do not require fine needle aspiration cytology or further investigation.

“…Echogenicity type is affected by the consistency of the content of the BCCs, which may vary depending on the presence of inflammatory processes (liquid-cystic, cystic-liquid with debris, pasty, suppurated). Pseudosolid appearance due to the presence of the protein content of the cysts produced by the epithelial lining [31]. On color and power Doppler ultrasound BCCs are avascular.…”

“…Cyst wall appears as hyper-or isoehoic linear structure, often avascular at Doppler ultrasound. The thickness of the wall may vary in different parts of cysts and reach 1.0cm in recurrent inflammations [30,31], but also thinning is possible, i.e. the wall becomes non-differentiable [4].…”

Schwannoma is a rare benign tumor originated from the Schwann cells of the nerve sheath. Other common names are neurilemmoma, neurinoma, and neurinoma of Verocay. The tumor is encapsulated and shows slow growth reaching even the 8.5-cm size. The purpose of this paper is to provide clinical presentation, sonogram and ultrasound video of schwannoma of the tongue, its analysis along with intraoperative and histopathological data. A 27-year-old female patient with tongue schwannoma is presented and analysis of the published schwannoma cases in different anatomical areas is performed. Distinctive sonographic features of this type of tumor are showed and comparison with the other tongue masses is highlighted. Ultrasonography proved its efficacy as a first-line diagnostic tool which needs to be popularized among oral and maxillofacial surgeons.
