Intrathoracic ribs are very rare congenital anomalies. Approximately 50 cases have been reported in the literature till date. They are usually present on the right side, between the third and eighth ribs without sex predominance. They may originate from a vertebral body or the proximal or distal part of a rib. In most cases, they are asymptomatic, but they may be associated with developmental abnormalities of ribs and vertebrae. The diagnosis is important to prevent further investigation or intervention. Here we present two rare cases with supernumerary intrathoracic rib and describe a novel sign, namely expansion of the rib head. To the best of our knowledge, this is the shortest supernumerary intrathoracic rib, reported in the literature, on the left side originating from the head of the second rib, which could have been misdiagnosed as osteochondroma due to its atypical features.Keywords: Intrathoracic rib, supernumerary, expansion of rib head, computed tomography, congenital anomaly ÖZIntratorasik kostalar çok nadir görülen anomaliler arasında yer almaktadır. Şimdiye kadar literatürde 50'ye yakın vaka bildirilmiştir. Genellikle sağ tarafta ve 3.-8. kosta orjinli olup cinsiyetler arasında sıklık farkı bulunmamaktadır. Vertebra gövdesinden, kostaların proksimal veya distal kesimlerinden köken alabilir. Vakaların çoğunda semptoma neden olmazken kosta ve vertebra gelişimsel anomalisi ile ilişki gösterebilir. Tanının doğru konulması ileri araştırılma veya girişimsel işlemlerin önlenmesinde önemlidir. Bu vaka takdiminde, süpernüme-rer intratorasik kosta anomalisi olan 2 hasta sunduk ve daha önce tanımlanmamış "kosta başı ekspansiyonu" bulgusunu tanımladık. Hastalarımızdan birindeki atipik bulguları nedeniyle osteokondrom ile karışabilecek sü-pernümerer intratorasik kosta anomalisi (Sol 2. kosta baş kesminden köken alan) şimdiye kadar tanımlanmış intratorasik kosta anomalileri arasında en kısası idi.Anahtar Kelimeler: İntratorasik kosta, süpernümerer, kosta başı ekspansiyonu, bilgisayarlı tomografi, konjenital anomali Eurasian

“…Intrathoracic ribs are uncommon congenital variation where an incomplete supra- or normonumerary rib follows an abnormal course in the intrathoracic cavity and may originate from a vertebra or a rib [3]. To our knowledge, 50 cases of intrathoracic rib have been appeared in the literature so far after first reported in 1947 [345678910].…”

Recognition of a rare intrathoracic rib with computed tomography: a case report

et al. 2017

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.
