We present a case of an 81-year-old man with multifocal Paget disease found on bone scan that was performed for incidentally diagnosed prostate cancer. The subsequent Ga-PSMA (HBED-CC) PET scan also displayed increased uptake in the same distribution. Multiple known tumors display increased Ga-PSMA uptake due to neovasculature. We postulate that increased(More)
BACKGROUND In this study, we prospectively evaluate the diagnostic potential of a gallium-68 (68Ga) prostate-specific membrane antigen (PSMA)-binding ligand and positron emission tomography (PET) in detecting metastatic lesions in patients with renal tumour. The secondary aim was to determine whether the findings would result in the alteration of patient(More)
A 29-year-old woman presented with a new right supraclavicular mass on a background of resection of a malignant melanoma from her right shoulder before 4 years. F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) imaging revealed uptake in a right supraclavicular node and the inferior pole of the left lobe of the thyroid(More)
AIM To determine the incidence of symptomatic versus incidental pulmonary embolism (PE) in oncology patients, characterize the nature and extent of incidental PE and the factors contributing to diagnosis. METHODS Specialized web search engine was used to identify oncology patients with positive imaging studies for PE. PE identified at staging CT scans(More)
A 49-year-old woman presented for investigation of a chronic cough. Computed tomography (CT) demonstrated a 12-mm diameter lobulated mass in the right middle lobe of the lung. There was no evidence of metastases on computed tomography and, particularly, no masses were demonstrated in the adrenal glands. Subsequent bronchoscopic biopsy demonstrated a poorly(More)
