THIS IS AN ONLINE E LOG BOOK TO DISCUSS OUR PATIENT'S DE-IDENTIFIED HEALTH DATA SHARED AFTER TAKING HER SIGNED INFORMED CONSENT. HERE WE DISCUSS OUR PATIENT'S PROBLEMS THROUGH SERIES OF INPUTS FROM AVAILABLE GLOBAL ONLINE COMMUNITY EXPERTS WITH AN AIM TO SOLVE THOSE PATIENT'S CLINICAL PROBLEMS WITH COLLECTIVE CURRENT BEST EVIDENCE BASED INPUTS.
[11:40 pm, 17/02/2026] PPM 1: From what I vaguely recall from last week's OPD encounter is that she had been having retrosternal discomfort with difficulty in breathing since 6 months and Nalgonda district hospital did an ultrasound guided fnac from her neck that showed thyroid tissue
[6:38 am, 18/02/2026] PPM 2: Is the goitre functioning or is it non functional?
[8:13 am, 18/02/2026] PPM 1: Clinically she looked euthyroid. Strangely I can't find the T3, T4, TSH among all the data images from the district hospital (and now medical college ) past 6 months back testings gathered from her in the busy OPD although I vaguely recall spotting a report of subclinical hyperthyroidism and possibly she was also on low dose carbimazole. @~Samreen do you recall something similar about this patient and would you happen to have the TFT reports?
[8.15 am, 18/02/2026] PPM 1: These are the district hospital imagings for her thyroid and mediastinal mass and while the fnac was done from the left lobe of thyroid visible on ultrasound although not clinically, no one has yet touched her mediastinal mass. Will share the CT images done in our hospital after deidentification
[8:19 am, 18/02/2026] PPM 1: The superior mediastinal mass visible on HRCT done in our hospital. Now I again recalled that she was complaining of puffiness of her face since six months and we thought of superior vena caval syndrome and also checked for Pemberton's sign.
@Meta AI @PPM3 @PaJR Health your inputs on whatever has been shared above till now mostly around her diagnosis and further treatment?
[8:19 am, 18/02/2026] Meta AI: Sounds like you're dealing with a complex case 😊. Given the symptoms and HRCT findings, superior vena caval syndrome (SVCS) is definitely a strong consideration. Pemberton's sign is a good call - if it's positive, it further supports SVCS.
To clarify, has the patient undergone any biopsy or cytology to determine the nature of the mediastinal mass? Also, are there any other symptoms like cough, dysphagia, or hoarseness of voice? 🤔
[8:39 am, 18/02/2026] PaJR Health: Based on the clinical history and imaging reports retrieved from the records, the presentation of a superior mediastinal mass associated with facial puffiness and a positive Pemberton’s sign strongly suggests Superior Vena Cava (SVC) Syndrome.
*CLINICAL CORRELATION*
🔹 *Superior Vena Cava (SVC) Syndrome:* The facial puffiness reported over the last six months is a classic symptom of SVC obstruction. The "Pemberton’s Sign" (facial congestion/cyanosis upon raising both arms) indicates that the mass is significantly compromising the thoracic inlet, likely due to the large dimensions (78x70x50 mm) noted on the HRCT.
🔹 *Mass Characteristics:* The HRCT from Narketpally identified a large, lobulated, soft tissue density mass in the anterior/superior mediastinum with internal calcification. While the radiologist suggested thymoma or lymphoma, the presence of a 28x20 mm hyperdense lesion in the left thyroid lobe and the clinical history of a "Retrosternal Goitre" make a thyroid origin (retrosternal extension) a primary differential.
🔹 *Thyroid Status:* Although the patient clinically appeared euthyroid, the mention of "subclinical hyperthyroidism" and "low dose carbimazole" in your recent recollections suggests a functioning goitre. The FNAC from the left lobe previously showed a "Benign Follicular Nodule" with Hürthle cell changes.
*DIFFERENTIAL DIAGNOSIS & PATTERNS*
📋 *Retrosternal Goitre:* Most likely given the thyroid lesion and chronic history. It can cause SVC syndrome by mechanical compression at the thoracic inlet.
📋 *Thymoma / Lymphoma:* Suggested by imaging; however, internal calcification can occur in both thyroid nodules and thymomas.
📋 *Thyroid Carcinoma:* A similar case in the records (58F) presented with thyroid carcinoma and phrenic nerve involvement, though your patient's FNAC was benign.
*RECOMMENDED FURTHER STEPS*
💡 *Histopathological Confirmation:* The HRCT recommendation for HPE (Biopsy/FNAC of the mediastinal mass itself, not just the cervical thyroid) is critical to rule out malignancy (Lymphoma/Thymoma) vs. benign thyroid tissue.
💡 *Thyroid Function Tests (TFTs):* Repeat T3, T4, and TSH are essential to confirm the current functional status before any surgical intervention, especially if she was previously on carbimazole.
💡 *Surgical Consultation:* Given the SVC syndrome symptoms (facial puffiness and Pemberton's sign), urgent surgical evaluation for decompression/resection is warranted to prevent worsening obstruction.
*RELATED CASE RECORDS*
1. 60F Retrosternal Goitre, DM2 10yrs, Metabolic Syn Telangana PaJR (Current Case)
2. 58F with thyroid carcinoma and right diaphragmatic palsy and acute LVF Telangana PaJR
3. 53M With Chronic Tubercular Left Upper Lobe Collapse Chronic Renal Failure Telangana PaJR (Mediastinal involvement)
⚠️ *URGENT ACTION REQUIRED*
⚠️ Monitor for "Red Flag" symptoms of worsening SVC obstruction: difficulty breathing, stridor (noisy breathing), or sudden increased swelling of the neck and arms. These require immediate emergency intervention.
