Case of Carcinoma Breast with Unusually Large Tumor Thrombus in Superior Vena Cava Detected on 18F-Fluorodeoxyglucose Positron Emission Tomography Computed Tomography Scan.

A 60-year-old female with triple negative breast cancer, postsurgery, neoadjuvant chemotherapy and radiotherapy, on follow-up had facial puffiness and giddiness. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) done for suspected recurrence evaluation revealed a large tumor thrombus (TT) in superior vena cava (SVC) with radiological evidence of SVC obstruction. 18F-FDG PET/CT also showed evidence of FDG avid brain metastases, lymph nodal metastases, and metastatic soft tissue deposits. This case of unusually large TT in SVC detected on 18F-FDG PET/CT highlights the ability of 18F-FDG PET/CT to identify TT and clearly demonstrate the pattern of disease in suspected recurrence in triple negative breast cancer patients.

Synovial Sarcoma of the Larynx: Report of a Case and Review of Literature.

Sarcomas account for less than 1% of malignant neoplasms arising in the head and neck in adults. Laryngeal synovial sarcoma is an extremely rare form of laryngeal malignancy with less than 20 cases reported in the literature. We report the case of a 48-year-old man with synovial sarcoma of the larynx. He underwent excision of the tumor followed by radiation. He is alive in remission at 36 months. The literature on synovial sarcoma of the larynx is reviewed.
