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 ...
Macrocystic have cysts greater than 2 cubic centimetres (0.12 cu in), and microcystic lymphatic malformation have cysts that are smaller than 2 cubic centimetres (0.12 cu in). [2] These malformations can occur at any age and may involve any part of the body, but 90% occur in children less than 2 years of age and involve the head and neck.
The cystic lymph node is situated at the neck of the gallbladder. [2] [4] It is invariably situated lateral to the biliary tree. [9] The node receives lymphatic drainage from the gallbladder, cystic duct, hepatic duct, and the superior portion of the common bile duct. [10] It in turn drains lymph into the hepatic lymph nodes.

Ultrasound examination is usually adequate in evaluating primary tumours and cervical lymph nodes. Preoperative cross-sectional imaging with CT or MRI is indicated if there is a concern for local invasion that may alter the patient's staging as well as surgical approach (Figs. 4, 55 and 6)6) .
A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct. Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages.
Most structures of the neck, including the thyroid and parathyroid glands, [24] lymph nodes, and salivary glands, are well-visualized by high-frequency ultrasound with exceptional anatomic detail. Ultrasound is the preferred imaging modality for thyroid tumors and lesions, and its use is important in the evaluation, preoperative planning, and ...
Medical imaging, such as abdominal ultrasound, may be used to distinguish a Sister Mary Joseph nodule from another kind of mass. [ 2 ] Gastrointestinal malignancies account for about half of underlying sources (most commonly gastric cancer , colonic cancer or pancreatic cancer , mostly of the tail and body of the pancreas [ 3 ] ), and men are ...
The malformation contains large cyst-like cavities containing lymph, a watery fluid that circulates throughout the lymphatic system. Microscopically, cystic hygroma consists of multiple locules filled with lymph. Deep locules are quite big, but they decrease in size towards the surface.
