Most vertebral haemangioma are asymptomatic and discovered incidentally. Sometimes the symptomatic lesions present with radiological signs of aggressiveness and their appearance resemble other aggressive lesions (e.g. solitary plasmacytoma).
We present a patient with large symptomatic aggressive haemangioma like lesion in 12(th) thoracic vertebra in which a magnetic resonance spectroscopy (MRS) was used to analyse fat content within the lesion. The lesion in affected vertebrae showed low fat content with 33% of fat fraction (%FF). The fat content in non-affected (1(st) lumbar) vertebra was as expected for patient's age (68%). Based on MRS data, the lesion was characterized as an aggressive haemangioma. The diagnosis was confirmed with biopsy, performed during the treatment - percutaneous vertebroplasty.
The presented case shows that MRS can be used as an additional tool for evaluation of aggressiveness of vertebral haemangioma like lesions.
大多数椎体血管瘤为无症状性病变,为偶然发现。有时,有症状的病变具有侵袭性的影像学表现,其外观类似于其他侵袭性病变(例如孤立性浆细胞瘤)。
我们报告了 1 例 12 胸椎大的侵袭性血管瘤样病变患者,在该患者中使用磁共振波谱(MRS)分析病变内的脂肪含量。受影响椎体的病变显示低脂肪含量,脂肪分数(%FF)为 33%。非受影响(第 1 腰椎)椎体的脂肪含量与患者年龄(68%)相符。基于 MRS 数据,病变被特征化为侵袭性血管瘤。在经皮椎体成形术治疗期间进行的活检证实了该诊断。
本病例表明,MRS 可作为评估血管瘤样病变侵袭性的附加工具。
