Results
- Ultrasound guided fine needle aspiration was successfully performed in 178 nodules revealing 144 nodules to benign,
23 malignant nodules and 11 nodules of indeterminate features.
All the results were confirmed by post-operative histo-pathological correlation.
- The demographic analysis of the studied patients revealed that most thyroid nodules are present in the ages ranged from > 40- 50 years (n = 22 representing 31.4% of the 70 patients included in our study),
however most of the detected nodules were benign.
Malignancy was higher in patients > 70 years representing 50% of nodules found in this group followed by those from 25-30 years with malignant nodules representing 33.3% of nodules found in this age group.
- Sensitivity and specificity of the ultrasound features suggesting malignancy were as follows; Hypo-echogenicity (34.1% & 51.8%),
Solid consistency (27% & 94%),
Ill-defined margins (100%),
No halo (40.7% & 70.9%),
Micro-calcifications (36.8% & 81.8%) and Intra-nodular vascularity (52.2% & 80.4%) respectively.

- Echogenic nodules (representing 8.5% of the examined nodules) and completely cystic nodules (representing 5.7% of the examined nodules) showed 100% sensitivity of being benign.
