Thyroid Nodule Treatment in Corpus Christi, TX

Thyroid nodules are discrete, solid or fluid-filled lesions within the thyroid gland that are distinct from the surrounding thyroid parenchyma. They are extremely common, detectable by ultrasound in up to 68 percent of randomly selected adults, and the overwhelming majority are benign. However, approximately five to fifteen percent of thyroid nodules harbor malignancy, making evaluation by a qualified physician essential. At Corpus Christi ENT Sinus & Allergy, Dr. Todd M. Weiss conducts a thorough evaluation of thyroid nodules to accurately risk-stratify each lesion and guide appropriate management from surveillance to surgical intervention.

How Thyroid Nodules Are Discovered

  • Incidentally on imaging performed for another reason (incidentaloma)—the most common scenario, as CT, MRI, and ultrasound of the neck are increasingly performed
  • During routine physical examination, when a nodule is palpable, typically greater than one centimeter in size
  • Patient-reported discovery of a neck lump
  • Workup of thyroid function abnormalities (hypothyroidism or hyperthyroidism)

Symptoms

Most thyroid nodules are asymptomatic. When symptoms do occur, they may include:

  • Dysphagia (difficulty swallowing) — from compression of the esophagus by a large nodule or goiter
  • Dysphonia (hoarseness) — from compression or invasion of the recurrent laryngeal nerve; a concerning symptom
  • A visible or palpable lump in the front of the neck
  • Neck pressure or discomfort
  • Symptoms of hyperthyroidism (palpitations, heat intolerance, weight loss, tremor) in functioning or “hot” nodules
  • Dyspnea (difficulty breathing) — from tracheal compression by a large or substernal nodule

Evaluation

Thyroid-Stimulating Hormone (TSH)

TSH is the initial laboratory test for all thyroid nodules. A suppressed TSH suggests a hyperfunctioning (toxic) nodule, which has a very low risk of malignancy; these nodules may not require FNA biopsy. An elevated TSH raises the concern for autoimmune thyroid disease.

Thyroid Ultrasound

Ultrasound is the primary imaging modality for thyroid nodule evaluation. It characterizes the size, composition (solid, cystic, or mixed), echogenicity, margins, calcifications, and vascularity of each nodule — features that stratify the risk of malignancy using the ACR TI-RADS or ATA risk classification systems. Ultrasound also evaluates cervical lymph nodes for suspicious features.

Fine-Needle Aspiration (FNA) Biopsy

FNA biopsy is the most accurate preoperative diagnostic test for thyroid nodule characterization. Under ultrasound guidance, a thin needle is passed into the nodule to aspirate cells for cytopathologic analysis. Results are reported using the Bethesda System for Reporting Thyroid Cytopathology, which stratifies findings from benign to malignant and assigns a malignancy risk percentage to guide management.

Management

Surveillance

Benign cytology (Bethesda II) warrants surveillance with serial ultrasound at 12 to 24-month intervals. Nodules that remain stable over two or more years may be followed less frequently. Growth of greater than 20 percent in two dimensions on follow-up ultrasound may prompt repeat FNA.

Surgical Resection

Surgery is indicated for: malignant or suspicious FNA cytology, indeterminate cytology with high-risk ultrasound features, symptomatic nodules causing compressive symptoms, hyperfunctioning nodules causing hyperthyroidism not amenable to other treatment, or patient preference after thorough discussion. Depending on the extent of disease, surgical options include thyroid lobectomy (removal of one lobe) or total thyroidectomy (removal of the entire gland). Dr. Weiss will discuss the most appropriate surgical approach, expected outcomes, and risks during your consultation.

Common Thyroid Cancers

  • Papillary thyroid carcinoma: the most common thyroid malignancy (approximately 80 to 85 percent of cases); typically slow-growing with an excellent prognosis
  • Follicular thyroid carcinoma: the second most common; cannot be reliably distinguished from follicular adenoma by FNA alone and requires surgical pathology
  • Medullary thyroid carcinoma: arises from parafollicular C cells; may be associated with multiple endocrine neoplasia (MEN) syndromes; elevated serum calcitonin is a diagnostic marker
  • Anaplastic thyroid carcinoma: rare but highly aggressive; requires urgent multidisciplinary management
