68Ga-PSMA-Avid Small Cell Lung Cancer on PET/CT: Incidental Second Malignancy in Treated Prostate Cancer
1From the Department of Nuclear Medicine and PET/CT, Apollo Gleneagles Hospitals, Kolkata, India.
Abstract:
Ga-prostate-specific membrane antigen (Ga-PSMA) PET/CT has shown excellent results in imaging of prostate cancer. Some nonprostatic malignancies can also demonstrate Ga-PSMA uptake, including primary lung adenocarcinoma. However, no such data are present for small cell lung cancer. We present the case of a 59-year-old man, where a second primary metastatic small cell lung cancer was discovered on Ga-PSMA PET/CT done for suspected recurrence of prostate cancer.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
