Thyroid masses should be differentiated on the bases of their
nature, i.e. benign or malignant. The diagnosis of thyroid
diseases was difficult; beside laboratory investigation which
yield some type of thyroid diseases, Nuclear Medicine,
Ultrasound, computerized tomography (CT) and magnetic
resonance imaging (MRI) have been used. The purpose of this
study was to evaluate the correlation between various
sonographic features of thyroid nodules and their risk for
malignancy in an attempt to suggest an optimal diagnostic
approach to further workup of these lesions.
In this study 50 patient with thyroid disorder were scanned
by ultrasound at radiation and isotope center–khartoum –sudan
(RICK ) before histopathology examination (fine needle
aspiration biopsy). Hgh-resolution sonography of the thyroid
gland was performed with a U/S machine(HDI 4000 scanner
(Philips Medical Systems) equipped with acommercially
available 8- to 13-MHz linear transducer with color and power
Doppler.capability

In this study, specific intra-group analysis of sonographic
features among benign and malignant nodules indicates that
only the presence of calcification is a statistically significant
predictor of malignancy. The presence of intrinsic
microcalcifications was 40% sensitive and 85.7% specific in
identifying malignancy, and hence the presence of intrinsic
microcalcification within a thyroid nodule indicates high risk of
malignancy. |
