Differentiating between Traumatic Pathology and Congenital Variant: A Case Report of Butterfly Vertebra
Butterfly vertebra is a rare congenital malformation of the spine, which is usually reported in the literature as an isolated finding. We describe a 40-year-old woman that presented to our emergency department with back pain and sciatica. Initial radiological evaluation revealed an incidental finding of a L4 butterfly vertebra in the anteroposterior and lateral view radiographs. The patient pre...
متن کاملCase report: imaging findings in a "butterfly" vertebra.
A "butterfly" vertebra is a rare congenital anomaly, presenting as a sagittal cleft in the vertebral body. In the literature it has been described as an isolated finding, but it can also be associated with various syndromes, such as Alagille, Jarcho-Levin, Crouzon and Pfeiffer syndrome. We present a case of a 35-year old man with chronic low back pain. The diagnosis of a butterfly vertebra of S...
متن کاملImproving vertebra segmentation through joint vertebra-rib atlases
Accurate spine segmentation allows for improved identification and quantitative characterization of abnormalities of the vertebra, such as vertebral fractures. However, in existing automated vertebra segmentation methods on computed tomography (CT) images, leakage into nearby bones such as ribs occurs due to the close proximity of these visibly intense structures in a 3D CT volume. To reduce th...
متن کاملCase of Atlantoaxial Dislocation with Assimilated C1, Absent Posterior C2, Butterfly C3, and Fused Subaxial Cervical Spine: Management Dilemma with Multiple Segmentation and Formation Defects
Segmentation defects are often seen with congenital atlantoaxial dislocation (AAD) though an associated absence of posterior arch of C2 and butterfly C3 is rare. Apart from rarity, the combination of formation and segmentation defects adds to the management dilemma. We report a case of AAD with assimilated atlas, absent C2 posterior arch, C3 butterfly vertebra with floating posterior elements, ...
متن کاملVertebroplasty of Cervical Vertebra
BACKGROUND The first vertebroplasty was performed by Harve Deramond in France in 1984 due to a hemangioma of cervical vertebral body. Procedure technique consisted of inserting a needle through the bony palate of the oral cavity. Bone cement injected under pressure not only fills the areas of bone loss. The heat released in the process of crystallization causes denaturation of pathological tiss...
