Summary
This summary is machine-generated.

Thyroid ultrasound aids in diagnosing thyroid diseases, but fine needle aspiration biopsy is crucial for accurate results, especially for nodules over 1-1.5 cm. Histopathology is needed for follicular neoplasms.

Area of Science:

  • Endocrinology
  • Radiology
  • Pathology

Background:

  • Thyroid ultrasound is a key diagnostic tool for differentiating thyroid and extrathyroid diseases.
  • Ultrasonography provides detailed images of thyroid structures, revealing typical patterns of certain pathologies.

Purpose of the Study:

  • To evaluate the role of thyroid ultrasonography in disease diagnosis.
  • To determine the necessity of fine needle aspiration biopsy (FNAB) and histopathology in conjunction with ultrasonography.

Main Methods:

  • Review of clinical experience with thyroid ultrasonography.
  • Correlation analysis between ultrasonography and histopathologic findings.
  • Assessment of the diagnostic accuracy of fine needle aspiration biopsy (cytopathology and histopathology).

Main Results:

  • Thyroid ultrasonography correlates imperfectly with histopathologic findings.
  • Fine needle aspiration biopsy is recommended for nodules >1-1.5 cm or suspicious lesions.
  • Cytopathology of FNAB is highly accurate, but follicular neoplasms require histopathology for definitive diagnosis.
  • Colour-flow Doppler ultrasonography offers supplementary information but is not essential for diagnosis.

Conclusions:

  • A combination of clinical findings, laboratory results, ultrasonography, and FNAB provides the most accurate diagnosis of thyroid diseases.
  • FNAB should be utilized without hesitation for suspicious thyroid nodules.
  • Histopathologic examination remains critical for differentiating benign and malignant follicular neoplasms.
