Systemic arterial pneumatosis in a neonate with necrotizing enterocolitis.

Ultrasound is exquisitely sensitive for the identification of portal vein pneumatosis, which in neonates is commonly caused by necrotizing enterocolitis. We describe the ultrasound finding of systemic arterial pneumatosis in a case of necrotizing enterocolitis associated with congenital heart disease. A combination of a patent ductus venosus and an extracardiac right-to-left shunt via the great vessels through a patent ductus arteriosus provided a pathway for the pneumatosis from the portal vein to the abdominal aorta.

Skeletal scintigraphic appearance of an auto-transplanted osteoarticular plug: epiphyseal transplant.

Nuclear medicine bone scan is an essential diagnostic imaging tool both for the diagnosis and staging of bone tumors and in the follow-up of these patients. It is very important that we be able to discriminate between normal variants, changes related to altered physical stress, and recurrent disease in order to interpret the bone scan meaningfully. We wish to report the appearance of the isotope bone scan, technetium 99m-labeled methylene diphosphonate ((99m)Tc-MDP), associated with an auto-transplanted osteoarticular plug (epiphyseal transplant) performed following limb amputation. This reconstructive surgery can give a potentially misleading appearance on the nuclear medicine bone scan if one is unfamiliar with this surgical technique.

Thoracic outlet syndrome with subclavian aneurysm in a very young child: the complementary value of MRA and 3D-CT in diagnosis.

Thoracic outlet syndrome (TOS) is rare in childhood. In adults, TOS results in compression of the neurovascular bundle (branches of the brachial plexus and the subclavian artery), but more than 95% of cases present solely with neurologic compression. We present a case of TOS in a very young child and describe the rare finding of subclavian artery compression and post-stenotic aneurysm. The clinical features, imaging workup, and surgical findings are discussed. The combination of three-dimensional MR angiography and CT was of great value in diagnosis and surgical planning.
