Radiology Rounds - Cystic Pancreatic Lesions

As cross-sectional imaging has become more common, there has been a marked increase in the incidental detection of cystic pancreatic lesions. It is estimated that more than a third of these are found in asymptomatic patients. Although knowledge of the natural history of cystic lesions is incomplete at this time, it is known that some cystic pancreatic lesions, including pseudocysts and serous c...

Radiology Rounds - August 2006 - Evaluating Pulmonary Nodules

Increased utilization of chest CT examination has resulted in a dramatic escalation in the number of newly detected solitary pulmonary nodules, defined as round lesions <3 cm in diameter surrounded by lung parenchyma. Although the risk of finding cancer is 3040% in radiographically discovered pulmonary nodules, thin section CT is 10-20 times as sensitive and can detect much smaller nodules. Siz...

Radiology Rounds - January 2008 - Cerebral Aneurysms

Data from autopsy studies indicate that 1-5% of adults have cerebral aneurysms. Most are considered to be sporadically acquired lesions although the risk is higher if an individual has a family history of aneurysms or autosomal dominant polycystic kidney disease. About 27,000 cerebral aneurysms rupture each year in the United States, resulting in subarachnoid hemorrhage. The peak incidence is a...

Radiology Rounds - August 2009 - Imaging for Sinusitis

Each year, nearly 31 million people in the USA are diagnosed with sinusitis, defined as an inflammatory process involving the mucous membranes of the paranasal sinuses. Symptoms of sinusitis include mucopurulent nasal discharge, nasal congestion, facial pain, pressure or fullness, and decreased perception of taste or smell. These symptoms result in substantial adverse effects on mood, physical ...
