Report of a rare cause of spinal cord compression: costal osteochondroma.
To describe a very rare cause of spinal cord compression, costal osteochondroma, which was present in a 16-year-old girl with a history of hereditary multiple exostoses.
Only four cases of expansion of costal osteochondroma into the spinal canal through an intervertebral foramen have been reported previously.
The origin of the osteochondroma at the head of the right 12th rib, the invasion of the spinal canal through the right T12-L1 intervertebral foramen, and the compression of the spinal cord were shown on computed tomography and magnetic resonance imaging. The exact extent of the osteochondroma, particularly the cartilage cap, was delineated accurately by magnetic resonance imaging. Complete excision followed by full recovery occurred 19 months after surgery.
Magnetic resonance imaging is the preferred method of investigation in cases of osteochondroma related to spine, because it allows for better pre-operative planning and helps to prevent incomplete excision of the tumor.
关于脊髓压迫症罕见病因的报告：肋骨骨软骨瘤。
描述一名患有遗传性多发性骨软骨瘤病史的16岁女孩中，导致脊髓压迫的一种极为罕见的病因——肋骨骨软骨瘤。
此前仅报道过4例肋骨骨软骨瘤通过椎间孔向椎管内扩展的病例。
计算机断层扫描和磁共振成像显示，骨软骨瘤起源于右第12肋头部，通过右T12-L1椎间孔侵入椎管并压迫脊髓。磁共振成像准确勾勒出了骨软骨瘤的确切范围，尤其是软骨帽。术后19个月完全切除肿瘤，患者完全康复。
磁共振成像为脊柱相关骨软骨瘤病例的首选检查方法，因为它有助于更好地进行术前规划，并有助于防止肿瘤切除不完全。
