Key Clinical MessageThe rare occurrence of Tarlov cysts in pediatric patients, particularly in the context of complex birth injuries, necessitates thorough evaluation and tailored management approaches. A comprehensive understanding of the clinical significance and optimal treatment strategies for this unique combination is crucial to ensure effective and individualized care for affected children.

“…When conservative measures fail and quality of life is significantly impacted, authors have advocated neurosurgical treatment, which usually involves a small laminectomy with cyst wall fenestration with or without packing the cyst cavity with autologous fat or excision while avoiding neural tissues [7-8]. Large case series showed complete or substantial improvement in more than 80% of patients who underwent surgery [9-10].…”

Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Our patient presented with radicular symptoms involving the left hand. Imaging workup revealed a cystic lesion of the left T1 nerve root at the level of the foramen. Surgical resection resulted in significant improvement in patient symptoms, and pathology revealed a perineural cyst. We conclude that a thoracic perineural (Tarlov) cyst can be symptomatic by causing nerve root compression and can be mistaken as a nerve root sheath tumor on imaging. Surgical treatment can be curative.

“…They are often multiple and small in size, with the S2/S3 nerve roots most commonly affected; although they may be found elsewhere [27][28][29][30][31] .The cyst wall is usually composed of dense, paucicellular collagenous bundles along with well-vascularized loose fibrous tissues. The cyst may contain neural tissue, nerve cell bodies, and occasionally, show the evidence of ischemic degeneration, trauma or repeated hemorrhage in its cavity or beneath the perineurium of the root.…”

Symptomatic Tarlov Cysts: an MRI evaluation of case series and literature review

et al. 2013

Aim:To analyze the characteristics of symptomatic Tarlov cysts by MRI. Materials and Methods:Neuroimaging and clinical outcome data were reviewed of 48 consecutive patients treated for symptomatic Tarlov cysts. All patients were scanned under Philips Gyroscan Intera 1.5T scanner with spinal surface coils. Two widely used surgical procedures were performed, 1) incision and drainage of the cyst with imbrication of the redundant nerve root sheath, and 2) exposure of the cyst, drainage of cyst contents, identification of nerve roots, and cyst wall resection combined with duraplasty. The post-operation follow-up was obtained from return visits to the neurosurgery and orthopaedic out-patient department or by telephone questionnaires.Results: All cystic lesions showed hypointense signal intensity on T1WI and hyperintense signal intensity on T2WI, but the nerve root showed iso-intensity on T1WI and low signal intensity on T2WI. They were linear in shape on sagittal view, and hypo intense dotted spots within the cysts on traverse view. Surrounding structures of the larger cysts were compressed and had bone erosions in some cases; the spinal canal and the intervertebral foramen on the affected side were enlarged. The lesions/cyst wall showed no enhancement after gadolinium administration.Conclusion: MRI will give a definite diagnosis of Tarlov cysts if nerve root presents within the cyst cavity or in the cyst wall; eliminating the need for histological confirmation. A correct analysis of the characteristics of symptomatic Tarlov cysts by MRI, will document its usefulness in noninvasive diagnosis and aid in exploration of the simplest treatment method.
