Spontaneous multiloculated multiseptated pneumomediastinum in a newborn baby: the spinnaker sail is rigged-CT features with pathologic correlation.

The CT appearance of a pathologically proven spontaneous multiloculated multiseptated pneumomediastinum in a newborn baby has not been reported in the English literature. Our baby was delivered vaginally at term and developed mild respiratory distress after birth. The antenatal history was unremarkable apart from borderline oligohydramnios.

Pleuropulmonary blastoma with a large embolic cerebral infarct.

We report on a 3-year-old girl who developed a large embolic cerebral infarct 1 day after an uneventful thoracotomy to remove a large pleuropulmonary blastoma. The tumour had encased the heart and great vessels and ruptured into the left hemithorax. Pleuropulmonary blastoma is a rare, but unique, primary thoracic neoplasm in young children and, to our knowledge, the development of a secondary large embolic cerebral infarct is also uncommon and has not been reported in this tumour.

Biliary atresia: making the diagnosis by the gallbladder ghost triad.

Objective: To describe the gallbladder ghost triad and evaluate its usefulness in the sonographic diagnosis of extrahepatic biliary atresia (BA).

Methods: From October 1997 to February 2002, 217 fasted infants with cholestatic jaundice aged 2-12 weeks were examined sonographically. We defined the gallbladder ghost triad as gallbladder length <1.
