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.

“…Reports of IMAC are few and to date, only 24 cases have been reported. [ 1 - 3 , 5 - 7 , 9 - 14 , 16 - 21 , 23 - 26 ]…”

“…Although most reports emphasize surgery for symptomatic cases, Fonseca and Ratilal demonstrated that clinical observation can be done in mild or asymptomatic cases. [ 7 ] The late presentation of symptoms in some adult cases can be used as a reference in support of observation of mild or asymptomatic patients. However, the literature is limited and we can only speculate about the natural history of IMAC at this point.…”

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.

“…Fenestration of the cyst with or without shunting to the subarachnoid space is another available treatment modality. Although surgery is the preferred approach in fact available one, a recent case reported by Fonseca and Ratilal [19] advocate "wait and scan" approach as a good therapeutic choice if patient is asymptomatic or mildly symptomatic.…”

“…Fonseca and Ratilal 2017 [19] 49 years/female Progressive cervical pain with episodic B/L distal paresthesia these lesions should undergo for surgical treatment as they afford very good clinical results, excellent prognosis and almost no recurrence. It's time to provide focused attention on their occurrences in asymptomatic patient.…”

Spinal arachnoid cysts are uncommon benign lesions of spine axis and most commonly present as compressive myelopathy. Intramedullary arachnoid cyst is uncommonly seen, hence, not much discussed in literature. Due to rarity of this entity, many questions are yet to be answered and should be addressed properly, particularly related to etiopathogenesis, accustomed course, behavior, differential diagnosis, and the best treatment modality. We report the clinicopathological profile of thoracic intramedullary arachnoid cysts in two adult patients, and present a detailed review of available literature on the spinal intramedullary arachnoid cyst. Most of the literature concerning with intramedullary arachnoid cysts are in the form of case reports from pediatrics population. As far to the best of our knowledge, only a few cases excluding our two were found in both pediatrics and adult population.
