title: Multidetector computed tomography evaluation of secondary hepatopulmonary fusion in a neonate.
abstract: Hepatopulmonary fusion is a rare condition in which a dense adhesion occurs between the right lung and herniated hepatic parenchyma in patients with right-sided congenital diaphragmatic hernia. Plain radiographic and magnetic resonance imaging (MRI) findings of hepatopulmonary fusion in a neonate have been reported in a retrospective study with a small patient population and a case report. However, to our knowledge, there is no report regarding the secondary hepatopulmonary fusion (after right-sided congenital diaphragmatic hernia repair) evaluated with multidetector computed tomography (MDCT) in a neonate. We report a case of secondary hepatopulmonary fusion in a neonate, in which multiplanar and three-dimensional (3D) images were helpful in delineating the precise anatomy for preoperative evaluation. Understanding the diagnostic limitations of plain radiographs and MRI, the use of MDCT with its multiplanar and 3D imaging may emerge as a useful noninvasive imaging modality in the evaluation of possible hepatopulmonary fusion in pediatric patients with right-sided congenital diaphragmatic hernia.
