BACKGROUND/OBJECTIVE: Spinal intramedullary tuberculoma is rare, accounting for 2/100,000 of cases of tuberculosis and only 2% of all cases of tuberculosis of the central nervous system. Diagnostic imaging is essential to improving diagnosis and management of this disease.
METHODS
The clinical profile, radiological data, and histological slides of 2 cases of intramedullary tuberculomas confirmed by pathologic examinations were reviewed.
RESULTS
In 2 cases, magnetic resonance imaging (MRI) showed thickening of the spinal cord and oval lesions with a low T1-weighted image signal and a typical "target sign" T2-weighted image signal. After gadopentetate dimeglumine administration, the lesion's rim shape was enhanced, showing uneven wall thickness and sharp margins.
CONCLUSIONS
MRI findings of spinal intramedullary tuberculoma were specific, and accurate diagnosis could be obtained. MRI is the optimal measure because it shows location, size, and number of lesions and the presence of degeneration and necrosis.
背景/目的：脊髓髓内结核瘤罕见，占结核病病例的2/100,000，仅占中枢神经系统结核病所有病例的2%。诊断性影像学对于改善该疾病的诊断和管理至关重要。
方法
回顾了2例经病理检查确诊的髓内结核瘤的临床资料、放射学数据和组织学切片。
结果
2例患者中，磁共振成像（MRI）显示脊髓增粗，椭圆形病变在T1加权像上呈低信号，在T2加权像上呈典型的“靶征”信号。静脉注射钆喷酸葡胺后，病变边缘强化，壁厚不均匀，边界清晰。
结论
脊髓髓内结核瘤的MRI表现具有特异性，可获得准确诊断。MRI是最佳检查方法，因为它能显示病变的位置、大小、数量以及是否存在变性和坏死。
