Abstract:
Three years after prostatectomy, a 78-year-old man with initial high-risk prostate cancer and new increasing prostate-specific antigen levels underwent Ga-prostate-specific membrane antigen (PSMA) PET/CT. Imaging revealed PSMA-positive pelvic, ascending retroperitoneal and left supraclavicular lymph nodes consistent with metastases. Additionally, there was PSMA-positive lymphadenopathy (hilar and mediastinal) and pulmonary changes (fibrotic and nodular) in which histopathology excluded metastases. A lymphocyte proliferation test was indicative of beryllium sensitization. Chronic beryllium lung disease-a multisystem granulomatous inflammatory disease mainly affecting the lungs-could be established in this patient with occupational exposure to beryllium. This case shows that manifestations of berylliosis can also be PSMA positive.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
