Symptomatic Tarlov cyst: report and review.
Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion. The cysts are relatively rare and most of them are asymptomatic. Some Tarlov cysts can exert pressure on nerve elements resulting in pain, radiculopathy and even multiple radiculopathy of cauda equina. There is no consensus on the appropriate therapeutic options of Tarlov cysts. The authors present a case of two sacral cysts diagnosed with magnetic resonance imaging. The initial symptoms were low back pain and sciatica and progressed to cauda equina syndrome. Surgical treatment was performed by sacral laminectomy and wide cyst fenestration. The neurological deficits were recovered and had not recurred after a follow-up period of nine months. The literature was reviewed and discussed. This is the first reported case in Thailand.
