Alaska's Western Arctic Caribou herd forms aggregations or groups that can stretch for miles. Once back in town the photos were laid out and areas of overlap marked so that no caribou were double-counted. It took 11 of us three days to put the overlap lines on photos, Dau said.
Chest Radiology > Pathology > Pericardial Effusion. Pericardial effusion causes an enlarged heart shadow that is often globular shaped (transverse diameter is disproportionately increased). A fat pad sign, a soft tissue stripe wider than 2mm between the epicardial fat and the anterior mediastinal fat can be seen anterior to the heart on a lateral view.
Pericardial effusion, and the possible inflammation of the pericardium resulting from it (called pericarditis), can have many possible causes, including: 1  Infection such as viral, bacterial or tuberculous. 2  Inflammatory disorders, such as lupus.3  Cancer that has spread (metastasized) to the pericardium. Antibiotics are used to treat pericardial effusions caused by an infection. 2  If a pericardial effusion is related to the presence of cancer, treatment may include chemotherapy, radiation therapy, or medication infused within the chest.
