Intravenous Tumour Thrombus from Papillary Carcinoma of Thyroid- A Case Report & Review of Literature

Thyroid carcinoma with extensive tumor thrombus in the superior vena cava: A case report

“…Tumor thrombus in the great vein is sometimes detected in patients with renal cell, adrenal cortical, testicular and hepatocellular carcinomas [3]. In 1879, Kaufmann and Graham reported the first two cases of vascular tumor thrombus associated with thyroid cancer [4].…”

Follicular thyroid carcinoma with internal jugular vein tumour thrombus

“…The condition may be accidentally diagnosed on imaging or as part of the routine peri-operative radiological evaluation. 1 , 6 Various imaging modalities exist for evaluating patients with suspected tumour thrombus. In the index case, ultrasound scan of the neck as part of the work-up for a possible completion thyroidectomy was the initial imaging study, even though the diagnosis was missed on the initial study.…”

“…The ultrasound scan was the only modality readily available at the peripheral facility of the various imaging modalities. Ultrasound scan of the neck is generally routinely used, 1 , 4 , 8 , 15 being widely available and non-invasive. 15 It is useful in characterising the tumours and identifying the location of extrathyroid masses 4 , 15 and for diagnosing small vascular tumour thrombi.…”

“…Tumour thrombus is the presence of tumour cells in great vessels. 1 Thyroid carcinoma with major cervical vascular tumour thrombosis is a very rare condition. 2 The reported incidence of tumour thrombus in thyroid carcinoma is about 0.2 – 3.8%.…”

“… 5 Most often, tumour thrombus by thyroid carcinoma is asymptomatic, 6 and may not be detected by clinical examination, not being palpable. 1 Imaging plays a vital role in patient assessment and diagnosis. 1 , 6…”
