Cysts that are clearly associated with threat of progressive neurological loss or intractable, unremitting symptoms should be released by a decompression procedure.In our case series, percutaneous aspiration has been successfully used for 3 of 4 PTs with marked decrease in size of cyst on imaging and clinical improvement.Obstructing pathology and ultimately the location of the cyst can be major factors in determining the success of the procedure.Our study demonstrated that a minimally invasive aspiration of a ZP SC can often achieve clinical improvement.This may save the PT from undergoing an invasive surgical decompression.
