3-D CT angiographic demonstration of a neonatal ductus arteriosus aneurysm with development of ductal calcification: are the "ductus bump", ductus arteriosus aneurysm, and ductal calcification related?
A "ductus bump" was noted as an incidental finding on a chest radiograph in a newborn infant with congenital cystic adenomatoid malformation. A chest CT performed on the first day of life demonstrated this to be a ductus arteriosus aneurysm (DAA), which subsequently thrombosed. Ductal calcification was noted on follow-up imaging. We propose that the "ductus bump" may actually be a DAA, which resolves presumably by thrombus formation. Ductal calcification may also be related to the regression of the thrombus.
