[Echographic identification of an isolated thyroid nodule].

Area of Science:

• Radiology
• Oncology
• Endocrinology

Context:

• Thyroid solitary nodules are common findings.
• Accurate characterization is crucial for patient management.
• Gray-scale ultrasonography is a primary imaging modality.

Purpose:

• To evaluate the efficacy of gray-scale ultrasonography in characterizing thyroid solitary nodules.
• To propose a novel classification system for thyroid nodules based on echographic patterns.
• To correlate ultrasonographic findings with histological confirmation.

Summary:

• 103 patients with thyroid solitary nodules underwent gray-scale ultrasonography.
• 79 of these patients had confirmed histological diagnoses.
• A multi-transducer computerized water-bath equipment (OCTOSON) was utilized.
• A proposed four-group classification is based on observed echographic patterns.

Impact:

• This classification may enhance diagnostic accuracy for thyroid nodules.
• It could aid in differentiating benign from potentially malignant nodules.
• The findings may refine the clinical management of patients with thyroid nodules.
