Intrathoracic Rib Associated with Pulmonary Collapse in a Pediatric Patient

The ribs are essential structures of the osseous thorax that provide certain significant information and aid interpretation of radiologicimages in daily routine practice. Intrathoracic rib is a rare congenital anomaly that is usually discovered incidentally, but may cause in vain interventions in case of being unaware. We herein report an intrathoracic rib in a girl whose chest X-ray was strange enough to obtain a spiral computed tomography (CT) scanning for a definitive diagnosis afterwards.
