MR imaging features of idiopathic thoracic spinal cord herniations using combined 3D-fiesta and 2D-PC cine techniques
Idiopathic thoracic spinal cord herniation (TISCH) is a rare cause of surgically treatable progressive myelopathy. The authors report 3 cases of TISCH diagnosed based on conventional T1- and T2-weighted Spin-Echo (SE) MR images in one case, and T1- and T2-weighted SE images combined with 3D-FIESTA (...

Summary: | Idiopathic thoracic spinal cord herniation (TISCH) is a rare cause of surgically treatable progressive myelopathy. The authors report 3 cases of TISCH diagnosed based on conventional T1- and T2-weighted Spin-Echo (SE) MR images in one case, and T1- and T2-weighted SE images combined with 3D-FIESTA (Fast Imaging Employing Steady state Acquisition) and 2D-Phase-Contrast Cine MR imaging in 2 cases. Conventional MRI findings usually provided the diagnosis. 3D-FIESTA images confirmed it, showing the herniated cord in the ventral epidural space. Moreover, in combination with 2D-Phase Contrast cine technique, it was a sensitive method to for the detection of associated pre- or postoperative cerebrospinal fluid spaces abnormalities.
La hernie médullaire idiopathique thoracique (HMIT) est une cause rare, chirurgicalement curable, de myélopathie chronique. Les auteurs rapportent 3 cas de HMIT dont le diagnostic a été porté par IRM sur des séquences pondérées T1 et T2 Spin-Echo pour un cas, et associées à des séquences 3D-FIESTA (Fast Imaging Employing Steady state Acquisition) et 2D Phase-Contrast Ciné dans 2 cas. Les séquences conventionnelles orientaient fortement le diagnostic. La séquence 3D-FIESTA le confirmait, en montrant la moelle herniée dans l’espace épidural antérieur. Son association avec la séquence ciné 2D-Phase-Contrast était sensible pour la détection des anomalies associées pré- et post-opératoires au niveau des espaces sous-arachnoïdiens. |
