131I Avid Tumor Thrombus in a Case of Poorly Differentiated Thyroid CancerSana Munir Gill, Aamna Hassan, Humayun Bashir, Waqas ShafiqShaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, PakistanIntravenous tumor extension is a well-recognized phenomenon occurring in various malignancies but is a relatively rare entity in thyroid carcinoma. In patients with poorly differentiated thyroid cancer, I-131 Avid Superior Vena Cava tumor (SVC) thrombus at initial presentation is infrequent and potentially life threatening. Tumor thrombus can form either due to direct vascular extension of the primary mass or by hematogenous spread. Hybrid nuclear imaging can potentially differentiate the two entities which can impact treatment plan of the patient. We present images of an interesting case of evolution of SVC thrombus in a 46-year-old female with diagnosed pDTC over the span of two years.
