Research Abstract:

A 65-year-old female with history of kidney transplant in 2009 presented with painful hand swelling. In 2019 a chest xray showed 4.4cm left lung mass with transbronchial biopsy demonstrating non-squamous cell lung carcinoma (NSCLC), PD L1+, treated with radiation therapy. A surveillance CT scan showed a new mass in left upper lobe 3.3 x 2.9 cm with positive avidity on PET scan. Lung biopsy 08/19/2020 showed NSCLC reoccurrence, treated with radiation. A PET scan on 04/15/2021 showed a new lung mass and FDG avidity in transverse colon, however a lung biopsy was negative for malignancy on 03/09/2022. Surveillance imaging for cancer remained negative until the patient presented with right arm pain. AV fistula ligation performed on 11/18/2022.
