Conclusion: Accuracy of a new sonographic classification system in differentiating benign from malignant solid thyroid nodules, while keeping FNAB
as gold standard was high and is recommended for diagnosis of malignant solid thyroid nodules.
The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) established 6 general diagnostic categories for describing thyroid FNAB
results, with each category implying a particular cancer risk and linking said risk to a rational clinical management.
The ultrasonography-guided FNAB
or core biopsy results were PTC (n = 6), PTC suspicion (n = 3), and an indeterminate follicular cell lesion (n = 2).
The sensitivity and specificity of the FNAB
investigation was 79% and 100%, respectively.
Descriptive statistics and specificities for diagnosis by CT, MRI, and FNAB
However recent studies have shown that ultrasound guided FNAB
has significant unsatisfactory cell sample for cytology evaluation4 and high false negative cytology in diagnosing malignancy especially for thyroid nodules if or more than 4 cm.

This paper provides an overview of the lung FNAB
procedure, relative contraindications, complications and nursing considerations.
Demonstrating v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations from the FNAB
sample further helps to distinguish AIP for malignant pancreatic disease, since KRAS mutation is found in 90% of patients with pancreatic cancer, but never in AIP [8, 9].
Arguably the best definition of FNAB
is in a textbook of cytology by de May and reads 'FNA biopsy can be defined as the removal of a sample of cells, using a fine needle, from a suspicious mass for diagnostic purposes' (1) Fine-needle aspiration biopsy (FNAB
), when performed by trained operators and for the correct indications, is a safe and minimally invasive procedure, with an excellent diagnostic yield.
Because the patient had obstructive symptoms and follicular lesion on FNAB
, right hemithyroidectomy and isthmectomy was done and histopathology findings were compatible with colloid goiter.
If an individual's FNAB
findings were diagnostic or suspicious for malignancy or follicular neoplasia, the person was referred for thyroid surgery.
