ABSTRACT
One of the uncommon congenital variations is intrathoracic rib which a normal, a bifid, or an accessory rib lies within the thoracic cavity that is founded accidentally. Clinically, in most cases they are without symptoms; however, it may cause intrathoracic problems therefore it is important for radiologists and physicians to identify to prevent of excessive intervention and treatment during imaging diagnostic techniques of thoracic problems. In this report, we provide the case of a rare presentation of an intrathoracic rib in a 3-year-old boy arising from the inferior portion of a second rib based on findings from computed tomography. To our knowledge, this is only the second reported case of this type of intrathoracic rib that demonstrated with computed tomography.

Costela intratorácica é definida como uma anomalia congênita rara, possivelmente causada por uma fusão incompleta dos processos cefálico e caudal dos esclerótomos durante a embriogênese. Frequentemente é achado incidental, porém, pode estar associada a malformações vertebrais e a alguns sintomas como dor torácica. O quadro apresentado é de costela intratorácica à esquerda, associada a malformação vertebral, com quadro clínico inespecífico.
Intrathoracic rib is defined as a rare congenital anomaly, possibly caused by an incomplete fusion of cephalic and caudal processes of sclerotomes during embryogenesis. Frequently, such abnormality is incidentally found, but may be associated with vertebral malformation and some symptoms such as chest pain. The authors report the case of a patient with left-sided intrathoracic rib in association with vertebral malformation, with a non-specific clinical picture.
