“…ere have also been reports of meningeal cysts developing secondary to inflammation, surgery, and other iatrogenic causes. [9,10] However, the overwhelming majority of meningeal cysts reviewed in the literature were reported to develop after trauma. [1,4,5] Since the Nabors classification, there have been a number of case reports describing interdural cysts.…”

Background: Interdural cysts are rare meningeal cysts with an unclear etiology. They are often mistaken for other mass lesions, including arachnoid cysts and tumors. Correctly identifying and classifying these cysts, as well as how they have formed in individual patients, are crucial to providing effective treatment options for patients. Case Description: We report a case of a patient with shunted idiopathic intracranial hypertension who developed a symptomatic Chiari malformation and was subsequently discovered to have a spinal interdural cyst. The Chiari malformation was likely due to intracranial hypotension secondary to lumbar cerebrospinal fluid (CSF) diversion. Once the shunt was removed, a spinal interdural cyst became clinically and radiographically evident, and the Chiari resolved, suggesting that both entities were effects of shared CSF flow dynamics. Conclusion: This cyst likely originated due to the trauma from remote repeated lumbar punctures and lumboperitoneal shunt placement, allowing CSF to enter the interdural space after the catheter was removed.

“…True interdural cysts of the spinal cord are rare entities [3]. Inflammation or infection can result in arachoiditis with the resulting sequestration of the spinal fluid in chambers that can grow and expand with time.…”

“…Intradural cyst of the spinal cord usually consist of spinal fluid-filled diverticula that can be found incidentally, or result in the compression of the nerve roots of the cauda equina, or of the spinal cord itself. While some can be congenital, other etiologies include inflammatory or infectious processes, or even traumatic events [1-3]. These events usually result in folds and adhesions in the arachnoid layer, or in a ball-valve phenomenon through an arachnoid fistula that can generate large bubbles, and compress the functional intradural components.…”

“…These events usually result in folds and adhesions in the arachnoid layer, or in a ball-valve phenomenon through an arachnoid fistula that can generate large bubbles, and compress the functional intradural components. However, a true cystic formation between the dural layers, also called interdural cyst, is very rare, with a handful of cases described in the literature [3-7]. To our knowledge there has only been one instance of traumatic interdural cyst that was reported in the literature, but that was due to a fistulous connection with the arachnoid layer of the nerve root sleeve.…”

Intradural arachnoid cysts are common entities that can be congenital, or caused by infectious, inflammatory, or even traumatic processes. However, true "inter"-dural cysts formed between the two lamellae of the lumbar dura without any fistulous arachnoid connection are rare. We present the case of a post-traumatic interdural cyst formation of the lumbar spine that compressed the roots of the cauda equina causing acute unrelenting pain. The cyst walls were formed by the true dural layers, and the cavity was filled with blood degradation products without any arachnoid connection to the subdural space. A commented video that details the diagnostic and surgical aspects of this case, alongside intraoperative footage is provided.

“…SAC can be idiopathic, traumatic, iatrogenic or congenital. 5 Congenital arachnoid cysts are mostly associated with neural tube defects and lacks inflammatory changes in histopathology specimen examination. 6 Intradural cyst can be associated with syringomyelia secondary to deranged cerebrospinal fluid (CSF) flow dynamics.…”
