Lung Metastasis From Prostate Cancer Revealed by 18F-FDG PET/CT Without Osseous Metastasis on Bone Scan.

A 54-year-old man, a case of prostate cancer, underwent radical prostatectomy and hormone therapy. Elevated prostate-specific antigen level developed 7 years later, but pelvic MRI and bone scan revealed negative results.

Dipyridamole Tl-201 myocardial single photon emission computed tomography in the functional assessment of anomalous left coronary artery from the pulmonary artery.

Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital heart disease. Without surgical correction, most patients with this anomaly die during infancy from myocardial infarction and heart failure, with a mortality rate reported to be greater than 90% by 1 year of age. Some patients with significant collateral circulation from the right coronary artery may remain asymptomatic and survive into adulthood, but they usually develop progressive left ventricular dysfunction.
