# Thyroid ultrasound for palpable thyroid nodularity
## STEP 1 — Gather Information
Perform a focused neck examination, palpating the thyroid gland for size, consistency, tenderness, and any discrete nodules; note patient’s acromegaly status (recent IGF-1/GH) and symptoms. If a palpable thyroid nodule is identified, proceed to step 2.
## STEP 2 — Rule In / Rule Out
Determine whether the palpable finding represents a true thyroid nodule versus normal thyroid tissue, muscular prominence, or cervical lymph node; rule out equivocal or non-thyroid masses. If a true thyroid nodule is confirmed, proceed to step 3; otherwise, no ultrasound is indicated.
## STEP 3 — Classify or Stratify
Assess nodule features: size ≥1 cm, firm/hard consistency, fixation to surrounding structures, associated dysphagia or voice changes, or prior radiation exposure. If the nodule meets any high‑risk criterion, proceed to step 4; for smaller, soft, mobile nodules without concerning features, clinical judgment may defer imaging but documentation is required.
## STEP 4 — Decide
Order a thyroid ultrasound (with grayscale and Doppler if available) to evaluate nodule morphology, vascularity, and presence of additional lesions.
## Clinical Guardrails / Mimics / Pitfalls
Do not delay ultrasound based on normal thyroid function tests; palpable nodules warrant imaging regardless of TSH or IGF-1 levels. Avoid mistaking a prominent thyroid cartilage or sternocleidomastoid muscle for a nodule. In acromegaly patients, do not rely solely on clinical surveillance because thyroid cancer prevalence is increased.
## Concrete Clinical Example
A 48‑year‑old woman with uncontrolled acromegaly (IGF‑1 800 ng/mL) presents for routine visit; exam reveals a 1.8‑cm firm, non‑tender nodule in the left thyroid lobe. Ultrasound shows a solid, hypoechoic nodule with microcalcifications, prompting fine‑needle aspiration for cytology.
