“…Some authors describe a 1%-5% incidence of TCs (Table 3). 23,26,33 The incidence does not significantly differ between sexes but is more prevalent in younger people: 4.0% in people less than 50 years of age old versus 1.3% in people greater than 50 years of age. Regardless of the classification system, the definition of a TC is histopathological, because it requires the presence of spinal nerve root fibers in the wall of the cyst or in its cavity.…”

“…The most common incidental lumbosacral lesions are vertebral hemangiomas, perineural cysts, fibrolipomas, synovial cysts, and sacral meningoceles. 23 One recent report indicates an 8.4% rate of incidental findings on lumbar spine MR imaging for suspected disc herniation or lumbar stenosis. 23 The prevalence of different incidental findings in the lumbosacral spine seems to vary significantly for age and sex.…”

“…The reported incidence of symptomatic TCs is approximately 1% or less (Table 3). 14,23,26 The clinical presentation of symptomatic cysts is nonspecific and similar to other disc or lumbar spine pathological entities. Symptoms that can be correlated to TCs include low-back pain, sacrococcygeal pain, perineal pain, sacral nerve root pain (sciatic pain), leg weakness, neurogenic claudication, bowel and bladder dysfunction, and sexual dysfunction.…”

“…According to the findings of previous studies, the lesions occur in about 1%-5% of patients. 23,26 Depending on their location, size, and relationship to the nerve roots, a subset of cysts may become symptomatic and cause sensory disturbances, motor deficits, or bowel/bladder dysfunction. This occurs in approximately 1% of patients.…”

The primary aim of our study was to provide a comprehensive review of the clinical, imaging, and histopathological features of Tarlov cysts (TCs) and to report operative and nonoperative management strategies in patients with sacral TCs. A literature review was performed to identify articles that reported surgical and nonsurgical management of TCs over the last 10 years. Tarlov cysts are often incidental lesions found in the spine and do not require surgical intervention in the great majority of cases. When TCs are symptomatic, the typical clinical presentation includes back pain, coccyx pain, low radicular pain, bowel/bladder dysfunction, leg weakness, and sexual dysfunction. Tarlov cysts may be revealed by MR and CT imaging of the lumbosacral spine and must be meticulously differentiated from other overlapping spinal pathological entities. They are typically benign, asymptomatic lesions that can simply be monitored. To date, no consensus exists about the best surgical strategy to use when indicated. The authors report and discuss various surgical strategies including posterior decompression, cyst wall resection, CT-guided needle aspiration with intralesional fibrin injection, and shunting. In operative patients, the rates of short-term and long-term improvement in clinical symptoms are not clear. Although neurological deficit frequently improves after surgical treatment of TC, pain is less likely to do so.

An 8-year-old boy was scheduled for urethral fistula correction under general anaesthesia with an ultrasoundguided caudal block. During scanning of the caudal area, we noticed two cystic structures in the caudal space in the region of the intended needle endpoint so we decided against performing the caudal block. Surgery was conducted uneventfully and a penile block was administered as an alternative for analgesia postoperatively. Radiological evaluation of the child 3 weeks later revealed the presence of perineural cysts in the sacral region. Routine use of ultrasound for caudal anaesthesia procedures may reveal unexpected anomalies in the sacral area, which could have implications for optimal patient management.

Incidental Findings of the Lumbar Spine at MRI During Herniated Intervertebral Disk Disease Evaluation

Abstract: Incidental findings at MRI of the lumbar spine were common and associated with age and sex. Most were benign findings. An awareness of the prevalence of the incidental findings detected at MRI of the lumbar spine is helpful for diagnosing lesions not related to symptoms.
