Throughout the area, sonography is usually the 1st and occasionally the single imaging modality for use after medical exam. this is often fairly precise for the cervical area. This e-book stories the sonographic positive factors of the cervical buildings, together with the thyroid, parathyroids, salivary glands, lymph nodes, larynx and hypopharynx, and blood vessels. distinctive morphological descriptions of various pathological strategies are supplied, through thorough dialogue of differential diagnostic difficulties. The function of the entire new technical modalities, together with high-definition grey scale, stronger colour Doppler, and ultrasound distinction brokers, is totally thought of. The ultimate bankruptcy is dedicated to using cervical sonography in pediatrics.

1 Papillary Carcinoma of the Thyroid The most frequent thyroid malignancy (>70% in all series), papillary carcinoma usually affects young females. This carcinoma has three main features: rhyroid Gland Fig. 22. 6-cm nodule is the largest in this patient with diffuse multinodular disease of the thyroid. If FNA is envisaged, this dominant nodule should be aspirated (a) it has a propensity for lymphatic spread, (b) its growth rate is slow, and (c) it is often multifocal. It rarely metastasizes (to the lung) and is often curable; the prognosis is often excellent.
Thyroid Gland 41 b a Fig. 45a,b. Sonographic features of Basedow's disease. a Transverse scan revealing discretely inhomogeneous enlargement of the thyroid and numerous dilated vascular structures throughout the parenchyma. b Sagittal scan revealing a discrete inhomogeneity in the echo texture, and especially the presence of vascular elements CASTAGNONE et al. (1996) did not observe any correlation between normalization of thyroid vascularity and reduction of hormone secretion in response to treatment.
24b: This lesion detected by US shows anarchic vascularity and especially poorly defined limits. c Same patient as in Fig. 8% of cases by Lv et al. (1994). Although the sonographic patterns are varied and the clinical presentation is not very suggestive, histological diagnosis of papillary carcinoma is usually facilitated owing to the presence of a characteristic papillary configuration and large, irregularly shaped nuclei (GHARIB 1997). All of these data underscore the utility of routine FNA cytology for all centimeterlarge thyroid nodules.
