Focal fibrocartilaginous dysplasia in the thoracic vertebra: A case report

Abstract

Focal fibrocartilaginous dysplasia (FFCD) is a rare, paraneoplastic disease that often presents in children and teenagers. Previous studies have reported cases of lesions in the proximal tibia and distal femur, as well as lesions in the upper extremities. The present study describes a case of FFCD on the transverse process and the rib. The imaging findings were found to correspond with the typical observations of FFCD and a biopsy from the nidus revealed pathological results similar to those of previous reports. Thus, the present study demonstrated that FFCD affects tubular bones as well as flat bones. Further studies are required to investigate the underlying mechanism and treatment of FFCD.

Tibia vara caused by focal fibrocartilaginous dysplasia: A rare case report

“…These cases involve various bones such as the tibia, 1 , 4 femur, 5 , 2 ulna, 6 , 7 humerus, 7 radius, 8 phalanx, 5 and vertebra. 9 Among these reported cases, the proximal tibia is recognized as the site that is most commonly affected.…”

Abnormal alignment of the left lower extremity and irregular gait

“…MRI demonstrates characteristic low-signal T1 and T2 intraosseous soft tissue component corresponding to the cortical lucency, surrounded by hypointense sclerotic bone [2]. The signal intensity of the soft tissue component is hypointense to the hyaline cartilage, similar to fibrocartilage.…”

“…The most common site of FFCD is the proximal tibia followed by distal femur, forearm, humerus, phalanx, and vertebra transverse process [2,3]. FFCD is most commonly noticed when children start crawling and ambulating [4].…”
