Biopsy thyroid, percutaneous core needle
CPT4 code
Name of the Procedure:
Biopsy thyroid, percutaneous core needle
Common Name: Thyroid Biopsy
Medical Term: Percutaneous Core Needle Biopsy (PCNB) of the Thyroid
Summary
A thyroid biopsy using a percutaneous core needle involves taking a small tissue sample from the thyroid gland through the skin. This procedure helps diagnose thyroid conditions by analyzing the tissue sample in a lab.
Purpose
A thyroid biopsy helps diagnose conditions like thyroid cancer, nodules, or goiters. It aims to determine the nature of a thyroid abnormality and guide further treatment.
Indications
- Presence of thyroid nodules detected by imaging
- Unexplained thyroid enlargement (goiter)
- Abnormal thyroid function tests
- Persistent neck pain or discomfort
- Suspicious findings on a physical exam
Preparation
- Fast for a few hours before the procedure, if instructed
- Inform the doctor about all medications and allergies
- Blood tests or imaging studies (e.g., ultrasound) may be required beforehand
Procedure Description
- The patient lies on their back with the neck extended.
- The skin over the thyroid area is cleaned and sterilized.
- Local anesthesia is administered to numb the area.
- Using ultrasound guidance, the doctor inserts a thin, hollow needle into the thyroid gland.
- Small tissue samples are extracted through the needle.
- The samples are sent to a lab for analysis.
Duration
The procedure typically takes 20 to 30 minutes.
Setting
Performed in an outpatient clinic or hospital radiology department.
Personnel
- Radiologist or endocrinologist
- Nurse or medical assistant
- Pathologist (for tissue analysis)
Risks and Complications
- Mild pain or discomfort at the biopsy site
- Bruising or swelling
- Minor bleeding
- Rarely, infection or injury to surrounding structures
Benefits
- Provides a definitive diagnosis of thyroid abnormalities
- Helps guide appropriate treatment plans
- Results are usually available within a few days
Recovery
- Minimal downtime; most patients can go home shortly after the procedure
- Keep the biopsy site clean and dry
- Avoid strenuous activities for 24 hours
- Follow-up appointment to discuss biopsy results
Alternatives
- Fine-needle aspiration (FNA), which uses a thinner needle but may be less conclusive
- Thyroid ultrasound alone without biopsy
- Surgical biopsy, which is more invasive but provides a larger tissue sample
- Watchful waiting with regular monitoring of the thyroid condition
Patient Experience
- Mild discomfort or pressure during needle insertion
- Local anesthesia helps minimize pain
- Post-procedure soreness managed with over-the-counter pain relievers
- Rapid return to normal activities with minimal restrictions
