PurposeIatrogenic dural tears during lumbar spine surgery are not uncommon and may have multiple long-term sequelae if not managed promptly and definitively. Sequelae include pseudomeningocoeles due to a persistent cerebrospinal fluid leak, which may result in a subarachnoid hemorrhage or subdural hematoma. These, in turn, can lead to adult communicating hydrocephalus. The purpose of this study is to describe a case of an intraoperative iatrogenic dural tear leading to the formation of a pseudomeningocoele and progressing to hydrocephalus.MethodsWe present a case of a 62-year-old female who had an iatrogenic dural tear during a lumbar decompression and instrumented fusion. Attempts at closure were unsuccessful, which led to the formation of a pseudomeningocoele and an ascending subdural hygroma, progressing into a communicating hydrocephalus which was treated with a ventriculoperitoneal shunt.ResultsImaging studies and clinical follow up after the incidental durotomy demonstrate complications arising from the persistent cerebrospinal fluid leak, beginning with the formation of the pseudomeningocoele and progression to hydrocephalus. Based on these imaging studies, it was possible to illustrate the development of each of the complications.ConclusionThe need for prompt recognition and proper management of iatrogenic dural tears are emphasized in order to avoid future complications that may arise from inadequate or proper treatment.
