Costela intratorácica: relato de caso

Abstract

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 leftsided intrathoracic rib in association with vertebral malformation, with a non-specific clinical picture.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.

Anatomofunctional comparison between the ribs of man and domestic animals

“…In most cases, horses have 18 pairs of ribs, eight sternal and 10 sternal, without flotation, and cattle 13 pairs, nine sternal and four sternal. However, according to Carvalho and Lopes (2012) and Milagres et al (2021), the number of rib pairs can also vary between individuals of the same species. Regarding the anatomical architecture, it was noted that canine, equine and bovine ribs are basically constituted by the same bone characteristics, including head, neck, body, costal tubercle, articular facet, costal groove and nutrient foramina (Figure 4) and, moreover, they do not have a spinal canal, confirming the scientific reports by Getty (1986).…”
