“…17 Both cyst types and the AVF can be encountered at the exit point of the nerve root (lateral recess) mimicking each other on MRI examination (hypointense on T1-weighted sequences and hyperintense on T2-weighted sequences).

BACKGROUND Spinal dural arteriovenous fistula is the most common spinal vascular malformation. It usually presents with neurological deficits due to venous congestive myelopathy. Sometimes, however, the symptoms are radicular and can imitate those of a disc hernia or synovial cyst. OBSERVATIONS In this illustrated case, a 34-year-old male patient presented with radicular pain due to nerve root compression. In the magnetic resonance imaging (MRI) examination of the spine, a synovial cyst was suspected, so the patient underwent no further examination before surgery. Intraoperatively, the authors were surprised to see a vascular malformation, which was shown to be an extradural arteriovenous fistula according to the histopathological examination. LESSONS In atypical MRI findings of the spine, vascular malformations should be considered. In cases with a spinal dural arteriovenous fistula, the thrombosis risk can be high and lead to a need for prolonged anticoagulation.

“…Specifically, the occurrence of hemorrhage within a Tarlov cyst is rare and indicates a potential intracystic vascular malformation, such as an arteriovenous fistula. Yoshikawa et al [19] reported a case of a sacral Tarlov cyst with intracystic hemorrhage and an accompanying arteriovenous fistula, which was treated with transcatheter arterial embolization. Additionally, Duja et al [20] reported a case of a hemorrhagic Tarlov cyst associated with cerebral infarction, possibly due to cerebrospinal fat embolism following cyst rupture, although not directly related to SCI.…”

Rationale: Caudal epidural block (CEB), which injects drugs into the epidural space through a sacral hiatus, is considered a safer alternative to other approaches. Serious complications, such as cauda equina syndrome or spinal cord infarction, have been reported very rarely, but their coexistence after CEB, which may be related to the ruptured perineural cyst, also known as a Tarlov cyst, was not reported. Patient concerns: A 40-year-old male patient presented with bilateral lower extremity radicular pain. CEB was performed without image guidance. The patient exhibited sensory deficits below L2, no motor function (0-grade), hypotonic deep tendon reflexes, and no pathological reflexes. Diagnoses: Spinal cord infarction, cauda equina syndrome, and sacral level perineural cyst with hemorrhage. Intervention: High doses of steroids and rehabilitation were performed. Outcomes: The patient was discharged after 28 days with persistent bilateral leg paralysis and sensory deficits below the L2 level. The patient demonstrated no neurological improvement. Lessons: Magnetic resonance imaging, including the sacral area, should be performed before performing CEB, to confirm the presence of a perineural cyst.
