Conclusions-In this study, we demonstrated abnormal pulmonary lymphatic perfusion in most patients with plastic bronchitis. Interruption of the lymphatic flow resulted in significant improvement of symptoms in these patients and, in some cases, at least temporary resolution of cast formation.

Cardiac MRI can predict the likely tumor type in the majority of children with a cardiac mass. A comprehensive imaging protocol is essential for accurate diagnosis. However, histologic diagnosis remains the gold standard, and in some cases malignancy cannot be definitively excluded on the basis of cardiac MRI images alone.

Lymphatic abnormalities are found in many patients after functional single-ventricle palliation. T2-weighted unenhanced MRI is capable of anatomic assessment of the lymphatic system in this patient population and has promise for guiding treatment in the future.

Congenital absence of the portal vein with systemic visceral venous return in a 8-year-old girl with oculoauriculovertebral dysplasia (Goldenhar Syndrome) had been previously reported following its discovery during preoperative evaluation of a liver mass which was diagnosed as focal nodular hyperplasia after open biopsy. Subsequently, an enlarging diffuse hepatic neoplasm developed with associated elevated alpha feto-protein levels. Repeat biopsy and imaging showed the tumor to be a hepatoblastoma involving both lobes of the liver. The patient was treated by hepatic resection and orthotopic liver transplantation and is doing well at 18 months follow-up.
