A newborn infant with intrathoracic mass: Answers


1. The patient’s lesion in the lung did not respond to antibiotic treatment, which eliminated pneumonia or atelectasis. Diaphragmatic hernia, teratoma, mediastinal neuroblastoma, intraor extralobar pulmonary sequestration, broncho-foregut malformations, such as cystic adenomatoid malformation or bronchogenic cysts, and intrathoracic kidney can cause this X-ray appearance, and these pathologies should be considered in the differential diagnosis [1–3]. 2. Patients with a suspected intrathoracic mass according to a chest X-ray require further evaluation, including Doppler ultrasound, computerized tomography (CT) scan of the thorax with intravenous contrast or magnetic resonance imaging [4]. These studies may delineate the lesion and its associated vasculature and determine whether any communication with the tracheobronchial tree exists [2, 4]. An intravenous pyelogram can be performed in such cases with suspected ectopic kidney [5]. 3. All patients should be evaluated for associated congenital disorders, in particular cardiac anomalies [2]. Rotational irregularities with the hilum facing inferiorly, distorted shape, elongated urethra, high origin of renal vessels and medial deviation of the lower renal pole can be associated with congenital intrathoracic kidney (CIK) [6, 7].
