We examined four patients with fluorosis, presenting with compressive myelopathy, by MRI, using spin-echo and fast low-angle shot sequences. Cord compression due to ossification of the posterior longitudinal ligament (PLL) and ligamentum flavum (LF) was demonstrated in one and ossification of only the LF in one. Marrow signal was observed in the PLL and LF in all the patients on all pulse sequences. In patients with compressive myelopathy secondary to ossification of PLL and/or LF, fluorosis should be considered as a possible cause, especially in endemic regions.
我们对4例患有氟中毒且表现为压迫性脊髓病的患者进行了MRI检查，采用自旋回波和快速低角度激发序列。在1例患者中显示出由于后纵韧带（PLL）和黄韧带（LF）骨化导致的脊髓压迫，另1例仅LF骨化。在所有脉冲序列上，所有患者的PLL和LF中均观察到骨髓信号。对于继发于PLL和/或LF骨化的压迫性脊髓病患者，应考虑氟中毒作为可能病因，尤其是在流行地区。
