Spinal arachnoid cyst

Presentation

The patient presented by back pain.

Patient Data

Age: 45 years
Gender: Female
Modality: MRI

Two intraspinal extramedullary lesions are seen abutting the posterior aspect of the dorsal cord and displacing it anteriorly. They follow CSF signal (low signal on T1, high signal on T2 with no post contrast enhancement) on all sequences. 

Case Discussion

Spinal arachnoid cysts are benign central canal lesions. On MRI they appear as masses with CSF-like signal (low signal on T1, high signal on T2 with no post contrast enhancement). The wall of an arachnoid cyst can not be appreciated in MRI.
