Objectives This article reports the management of a case of a 32-year-old male who presented with progressive weakness in the lower limbs and spastic paraparesis secondary to an intramedullary arachnoid cyst (IMAC). For literature review, the authors used the phrase “intramedullary arachnoid cyst” in PubMed search engine. 23 articles describing cases with IMAC were included in this review, with a total of 26 patients. Materials and Methods We report a case with long term recurrant intramedullary arachnoid cyst and present a review on spinal intramedullary arachnoid cyst. Result IMAC is showing bimodal incidence and trending to occur below 10 years and after 30 years. However, rarely, it should be considered in the differential diagnosis of intramedullary cystic lesions. Authors suggest doing laminoplasty or fusion for the pediatric patients to prevent kyphoscoliosis deformity in the long run, but doing early surgery to gain better outcome. Resection of the cyst wall should be done as much as possible; if it could not be achieved, then marsupialization or cysto-subarachnoid shunt should be considered. Aspiration alone or fenestration is not enough to eradicate the cyst. Long-term and prospective studies are recommended to achieve the best treatment options. Conclusion Review supports early surgical treatment of symptomatic IMACs with resection of the cyst wall as much as possible.

Background: Spinal intramedullary cysts present a radiological dilemma. We present a rare case of a conus intramedullary arachnoid cyst and report on its differentiating features and management. Case Description: We report a case of a 30-month-old child who presented with decreased gluteal sensation and urinary dribbling for 6 months. Apart from some slowness in walking, the power was normal in all four limbs. Imaging showed a non-enhancing, T2-weighted hyperintense 12 × 8 mm conus intramedullary cyst without any edema. A T12-L1 laminotomy followed by marsupialization of the cyst was done. Histopathology was suggestive of an arachnoid cyst. The postoperative course was uneventful with improvement in muscle strength and achievement of regular milestones. We also present the pertinent review of the literature to date. Conclusion: Intramedullary arachnoid cysts are a rare entity and should form the differential diagnosis for cysts presenting in the conus medullaris. Simple decompressive options may suffice for symptomatic cases and radical excision may be avoided. A high index of suspicion is essential considering the subtle nature of presenting symptoms.
