BACKGROUND: The association of tumor size with malignancy in thyroid nodules with indeterminate cytology: atypia/follicular lesion of undetermined significance (AUS/FLUS), suspicious for follicular (SFN)/Hürthle cell neoplasm (HCN), and suspicious for malignancy(SM) has not been clearly studied. STUDY DESIGN: We retrospectively identified 1,104, patients who underwent thyroid FNA and subsequent thyroidectomy. Patients with indeterminate cytology were reviewed. The size of the nodule was determined by ultrasound...

We present a case illustrating the rare complication of acute generalized thyroid swelling shortly after sonographic-guided fine needle aspiration of a thyroid nodule. Ultrasound revealed the presence of characteristic linear hypoechoic avascular areas interspersed throughout the gland suggestive of edema. The patient was treated conservatively, with near complete normalization of the thyroid within 24 hours. Recognition of this potential complication is important, as the rapid onset of diffuse thyroid enlargement is often alarming but typically has a transient and self-limiting course...

Thyroid is a small gland situated at the anterior side of the neck and one of the largest glands of the endocrine system. The abrupt cell growth or malignancy in the thyroid gland may cause thyroid cancer. Ultrasound images distinctly represent benign and malignant lesions, but accuracy may be poor due to subjective interpretation. Computer Aided Diagnosis (CAD) can minimize the errors created due to subjective interpretation and assists to make fast accurate diagnosis. In this work, fusion of Spatial Gray Level Dependence Features (SGLDF) and fractal textures are used to decipher the intrinsic structure of benign and malignant thyroid lesions...

CLINICAL ISSUE: In the daily clinical routine characterization of focal lesions using native B‑mode classical ultrasound and color Doppler can be difficult or insufficient; therefore, additional diagnostic information must be taken into consideration. STANDARD RADIOLOGICAL METHODS: Standard radiological methods in the daily clinical routine include native B‑mode ultrasound and color Doppler ultrasound. METHODICAL INNOVATIONS: Using sonoelastography it is possible to evaluate and characterize tissue properties and focal lesions regarding their stiffness to acquire additional information on a noninvasive basis...

Postoperative spindle cell nodule (PSCN) is a very rare pathologic complication that can occur in association with a recent core needle biopsy, surgery, or trauma. Cases of PSCN have been reported in the lower genitourinary tract, endometrium, and thyroid but are rare in the breast. Herein, we report an ultrasound-guided biopsy-proven PSCN after ultrasound-guided vacuum-assisted excision in the breast.
