The term meningocele manqué (MM) was coined in 1972 to describe a broad range of surgical findings characterized by intradural bands tethering neural structures to the dorsal dura. Over the following decades, reports continued to lump intradural tethering bands associated with a variety of comorbidities under the umbrella term MM. In more recent years, disorders previously called MM have been identified as embryologically distinct and have been reclassified. While this continues, there remains a set of intradural tethering disorders for which there is no better term than MM. Herein, we comprehensively review the literature surrounding MM including its embryology, its clinical, radiographic, and surgical presentation, and alternative classification methods and treatment.
