An Adult Cervical Intramedullary Arachnoid Cyst: Case Report and Review

Abstract

Lino Fonseca and Bernardo Ratilal

Spinal arachnoid cysts are uncommon benign lesions that occur in the spinal axis, and can cause spinal cord or nerve roots compression and may become clinically relevant. The authors report a 49-year-old woman who presented progressive onset of cervical pain with distal paraesthesia of the upper limbs associated to an intramedullary arachnoid cyst in the mid-cervical spine diagnosed by MRI. From the literature review, only six cases in patients over 18-year-old were found, all with thoracic location and one with cervical extension, and all were submitted to decompressive surgery. The authors described the first intramedullary arachnoid cyst with a wait and scan approach.
