“…Adenolipoma of the thyroid is a nodule composed of mature adipose tissue surrounded by a fibrous capsule, and it is associated with proliferation of thyroid follicles without cytologic atypia or capsular or vascular invasion. With the exception of location, its US characteristics including an ovoid shape, homogeneity, and hyperechogenicity 32 are similar to those of phantom nodules.…”

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.

“…This localisation requires further investigations to exclude a possible connection to the thyroid gland [ 2 ]. Intraglandular tumours of the parotid gland and other glands have been described in the medical literature [ 10 ] [ 11 ]. In our patient, the cytological data from the fine needle aspiration biopsy showed an origin from the adipose tissue with a benign nature.…”

BACKGROUND:Lipomas are benign formations with the mesenchymal origin, which are found in the head and neck region in a very small percentage of cases. In these cases, they usually occur in the posterior neck and usually grow very slowly without causing complaints. However, when they cover the front of the neck, it is necessary to confirm the adipose origin of a tumour and to exclude the connection with the thyroid gland. Although in principle, lipomas are benign, there are three more unfavourable possibilities of 1) malignancy of lipomas, 2) the occurrence of de novo liposarcomas or 3) the association of lipomas with other tumours, such as retinoblastoma.CASE REPORT:We present a 74-year-old woman with a painless subcutaneous formation in the neck. A Fine Needle Aspiration Biopsy (FNA) was performed, with the conclusion of the cytological result for lipoma. Surgical removal was planned under general anaesthesia.CONCLUSION:Usually, lipomas do not require surgery, but when they engage muscles they become indicative of surgical treatment.
