An attempt to reduce unnecessary surgical procedures... Can ultrasound characteristics help in differentiating adenoma vs carcinoma in follicular thyroid neoplasms?

Introduction And Objectives: Thyroid nodules frequently require ultrasound and Fine Needle Aspiration Cytology (FNAC) evaluation. However, FNA cytology does not allow differentiation between follicular adenoma and carcinoma on Bethesda type IV lesions. This situation leads to many unnecessary surgical procedures because it is not possible to assure the benignity of the lesions, even when most of the specimens correspond to adenomas or even other benign lesions.

Superficial artery aneurysms underlying nummular headache--2 cases and proposed diagnostic work-up.

Introduction: Nummular headache, considered a primary headache in the 3rd edition of the International Classification of Headache Disorders, has nonetheless been attributed in several occasions to underlying epicranial anomalies.

Case Reports: Vascular imaging of the head in 2 patients with nummular headache revealed fusiform aneurysms of the scalp vessel in close relation to the painful area. One of the patients underwent surgical resection of the aneurysm with excellent response.

Utility and interobserver agreement of ultrasound elastography in the detection of malignant thyroid nodules in clinical care.

Background And Purpose: Malignancy correlates with hardness of tissues and US elastography can potentially analyze the stiffness of lesions. Our aim was to evaluate the utility of US elastography in the detection of malignant nodules and to investigate interobserver agreement with this technique.

Materials And Methods: One-hundred three consecutive patients with 106 thyroid nodules were examined prospectively with conventional B-mode sonography and real-time US elastography.

[Ocular blood flow and characteristics of retinal detachment].

Purpose: To determine if ocular blood flow (OBF) changes in retinal detachment (RD) are related with its characteristics (extension, macular involvement, PVR or duration).

Methods: 60 patients with unilateral rhegmatogenous RD and 20 <> patients were selected. Color Doppler Ultrasound was used to measure OBF velocities in the ophthalmic artery (OA), central retinal artery (CRA) and vein (CRV) and posterior ciliary arteries (PCA) of both eyes of each patient.
