“…They are often multiple and most prominent in the sacral region. Extradural meningeal cysts are more frequent in patients with connective tissue disorders 1 . CT density and MR signal match that of the CSF and they demonstrate no contrast enhancement.…”

“…Widening of the dorsal subarachnoid space with smooth indentation of the spinal cord may be the only finding on conventional sequences. Dorsal CSF flow artifacts may be diminished at the cyst's level and CT myelography will show a filling delay or defect 1,2,22 . When symptomatic, surgical resection or fenestration is indicated 22 …”

“…Dermoid/epidermoid are inclusion cysts that can be congenital (frequently associated to dysraphism) or acquired, due to iatrogenic introduction of dermal/epidermal tissue during lumbar puncture or spinal surgery 26 . They occur most frequently in the intradural extramedullary compartment and in the lumbosacral spine 1,22 . Dermoid cysts typically show fat‐like hypodensity on CT, with possible coexisting heterogenous structures (such as hair and gland elements).…”

Several distinct conditions present as cystic or pseudocystic lesions within the spinal canal. Some of the most common spinal cystic lesions include spinal meningeal cysts, juxtafacet cysts, dermoid/epidermoid cysts, nerve sheath tumors, and syringohydromyelia. Clinical presentation is usually nonspecific and imaging characteristics are frequently overlapping, which may pose a challenging presurgical diagnosis. We provide a pictorial review of cystic intraspinal lesions and discuss the main imaging features that can aid the neuroradiologist in the differential diagnosis. First, we propose a categorization of the lesions according to their location as extradural, intradural extramedullary, and intramedullary. This is a crucial initial step in the diagnostic workup and surgical planning. Second, for each of these locations, we organize the lesions according to their etiology: congenital and developmental disorders, degenerative disorders, traumatic or postsurgical collections, infectious conditions, neoplastic lesions, and other miscellaneous disorders. Finally, we summarize the clinical highlights and MR features that provide important insights for the differential diagnosis. MR is the technique of choice in presurgical evaluation and postsurgery follow-up. It provides accurate lesion localization and characterization and, most of the times, it will allow a confident differential diagnosis.High-resolution three-dimensional T2-weighted sequences and diffusion-weighted imaging can provide important hints in specific cases. Signal correlation with T1-weighted and fat-saturated sequences allows to differentiate true cystic lesions from hemorrhage or fat tissue.
