Abstract

The authors describe the case of a fifteen-year-old girl with progressive paraparesis of the lower limbs that was caused by an intraspinal extradural dorsal arachnoid cyst at the level of Th 3-6. Diagnosis was established with MRI and MRI myelography. The latter revealed the CSF-like content of the cyst. The patient underwent laminotomy and en bloc resection of the cyst. Ligation of the pedicle of the cyst was done with laminoplasty. Quick and complete recovery was observed after surgery.

Zusammenfassung

Die Autoren beschreiben den Fall eines 15-jährigen Mädchens mit progressiver Paraparese, die durch eine extradurale dorsale intraspinale Arachnoidalzyste auf dem Niveau Th 3 bis 6 verursacht ist. Die Diagnose wurde durch MRl und MR-Myelographie gesichert. Letztere zeigte den wassergleichen lnhalt der Zyste. Nach Laminotomie und en bloque Resektion der Zyste ist der Pedikel der Zyste reseziert worden, und eine Laminoplastik schloss den Eingriff ab. Nach der Chirurgie trat eine schnelle und komplette Erholung ein.
