Watch the full video lecture on YouTube: https://www.youtube.com/watch?v=UxFcjVs0Jng ## 🩺 Clinical Case Discussion : Solitary Thyroid Nodule Today, we'll have a clinical case discussion on a very common ENT presentation: **Solitary Thyroid Nodule (STN).** This case discussion format will be helpful for both undergraduates and postgraduates. We'll go through the patient's history, discuss how history guides us to a provisional diagnosis, cover the clinical examination findings and their significance, summarize the case, arrive at a provisional diagnosis, and outline the management plan. --- ### 📋 Patient History **Patient Demographics:** - **Age:** 36 year old female - **Residence:** Mumbai - **Occupation:** Homemaker **Chief Complaint:** - Swelling in front of the neck for 3 years. --- ### 📜 History of Present Illness - **Onset:** Insidious, noticed 3 years ago. - **Progression:** Gradually progressive, from ~2×2 cm to ~4×4 cm. - **Nature:** Painless swelling, midline anterior neck. - **Pattern:** Slowly progressive, no sudden changes. > **Gradual progression** → Suggests benign swelling. >What does Rapid increase VS Sudden increase in size of Thyroid swelling indicate? --- ### ❌ Negative History & Its Significance | Symptom | Significance if Present | | --- | --- | | Change in voice (hoarseness) | RLN palsy → Red flag for carcinoma thyroid | | Pain / Fever | Suggests thyroiditis, abscess, TB lymphadenitis | | Dysphagia | Large goiter compressing esophagus / malignant infiltration | | Odynophagia | Thyroiditis, malignant infiltration | | Dyspnea | Tracheal compression, deviation, or infiltration | | Stridor | Impending airway compromise → urgent evaluation | | Palpitations | Thyrotoxicosis (Graves, toxic nodule) | | Chest pain | Cardiac (thyrotoxicosis-related angina) / mediastinal invasion | | Appetite/Weight change | Hyperthyroid vs hypothyroid clues | | Heat/Cold intolerance | Hyperthyroidism vs hypothyroidism | | Irritability, tremors, lethargy | Hyper vs hypo features | | Eye signs (diplopia, exophthalmos) | Graves' ophthalmopathy | | Altered bowel habits | Diarrhea (hyper), constipation (hypo) | | Cough/hemoptysis | Tracheal invasion, retrosternal goiter, lung metastasis | | Other swellings | Lymph nodes (papillary Ca spread), pulsatile bone mets (follicular Ca), MEN syndrome masses | | Previous neck surgery | Recurrent goiter, residual carcinoma | | Radiation exposure | Major RF for papillary carcinoma | --- ### 🧬 Past, Family, Personal & Menstrual History - **Past Medical:** No thyroid medication use, no prior surgeries. - **Drug history:** No use of amiodarone, lithium, interferons, etc. - **Family History:** No thyroid malignancy / MEN syndrome features. - **Personal History:** Normal appetite, sleep, diet. No addictions. - **Menstrual/Obstetric History:** Normal cycles, 2 healthy children. >What are the different drug history relevant to thyroid swelling? Why is it important? >What is MEN Syndrome? Which one is associated with Thyroid cancer and what are the features you see in it? >What are the genes involved in MEN Syndrome? >What is the importance of taking Menstrual history in a thyroid case? >What are the clinical features of Hypothyroidism? >What are the clinical features of Hyperthyroidism? >What is difference between Hyperthyroidism and Thyrotoxicosis? --- ### 🔬 Clinical Examination Findings **General & Systemic Examination:** Normal. **Local Neck Examination:** - **Inspection:** - Single globular swelling, anterior midline (4×4 cm). - Extent: Below thyroid cartilage to 2 cm above sternal notch. - Moves with deglutition, not with tongue protrusion. - Skin normal, no scars/sinuses/pulsations/veins. - Trachea midline. - Pemberton’s sign negative. - **Palpation:** - Firm, smooth, well-defined margins. - Non-tender, mobile in vertical & horizontal planes. - Lower border palpable. - Skin pinchable. - No bruit, no cervical lymphadenopathy. - **Percussion:** Resonant over manubrium sterni → no retrosternal extension. - **Auscultation:** No bruit. - **Carotids:** Palpable bilaterally (Berry’s sign negative). >What are the neck swellings that move with deglutition? >What is a neck swelling that move with protrusion of tongue? >When do you see visible pulsations in Thyroid swelling? >When do you see Engorged Veins in Thyroid swelling? >What is Pemberton sign? How do you elicit it? What is the mechanism behind it? Name some condiitons where you see it. >Why do Thyroid swellings grow downwards, and not up? >What are the different Methods of Thyroid Palpation? >What is Thyroid paradox? >Where should you auscultate for bruit in a thyroid swelling? Why? >What is Berry's sign? --- ### 📝 Case Summary A **36-year-old female** presents with a **solitary, midline, anterior neck swelling** for 3 years. - Swelling is **firm, mobile, smooth-surfaced, moves with deglutition but not tongue protrusion**, and has **no pressure symptoms**. - **No clinical features of thyroid dysfunction** (clinically euthyroid). - No lymphadenopathy. --- ### 🩺 Provisional Diagnosis **Solitary Thyroid Nodule, Left Lobe — Probably Benign, Clinically Euthyroid.** >What are the points in favour of your diagnosis? >What are the Points to note in Provisional Diagnosis? >What is the Differential Diagnosis of Solitary Thyroid Nodule? >What is Dominant nodule in Multinodular Goiter? >What is Lateral Aberrant Thyroid? >What is the Most common site of nodule in Thyroid? --- ### 🏨 Management Plan Management always consists of two parts: Investigation and Treatment. **Investigations** 1. **Thyroid Function Tests (TFTs):** To confirm euthyroid / hypo / hyperthyroid status. 2. **Ultrasound Neck (First-line imaging):** - Confirm thyroid origin, size, solid/cystic, vascularity. - Look for malignant features → hypoechoic, taller-than-wide, microcalcifications. - Assess for cervical lymph nodes. 3. **FNAC (Gold Standard):** Report via **Bethesda system**. - Cannot distinguish follicular adenoma vs carcinoma. 4. **Laryngoscopy:** To assess vocal cord mobility (mandatory pre-op). 5. **Other (selected cases):** - Radionuclide scan (only if TSH low → hot vs cold nodule). - CT/MRI (retrosternal goiter, tracheal compression). - Antibody tests (Hashimoto’s suspected). >What is TIRADS? >What is Bethesda System for Reporting Thyroid Cytopathology? **Treatment** - Left Hemithyroidectomy under General Anesthesia >What are the Surgical Indications in Solitary Thyroid Nodule? >What are the Steps of Hemithyroidectomy? >What are the Complications of Thyroidectomy? --- ✅ **Final Takeaway:** This case is a **benign solitary thyroid nodule** in a clinically euthyroid young female, most likely managed by **hemithyroidectomy** with excellent prognosis. --- ## About This Note This free ENT note on Clinical Case Discussion: Solitary Thyroid Nodule was written by Dr. Mausumi Das and is paired with a corresponding video lecture.
