Global incidence of spinal perineural Tarlov ’s cysts and their morphological characteristics: a meta-analysis of 13,266 subjects

ConclusionsSpinal perineural (Tarlov) cysts are found in a minority of population. S2 level of the sacral bone is affected most frequently. There is female predominance. Correspondence with symptoms is seen in less than one-fifth of TCs. Studies with stronger evidence level are needed to corroborate the results. The purported high incidence in PGAD requires confirmation in case –control studies for the risk-ratio calculation.
