Three patients presented with rare intrasacral extradural arachnoid cysts manifesting as sensory deficiencies and pain in the lower extremities. Magnetic resonance imaging with various sequences identified the cysts. Two patients underwent surgery via laminectomy of the sacrum for cyst exploration and disconnection of the cyst with the dural theca. Postoperative outcome was favorable in these two patients. Intrasacral extradural arachnoid cyst should be considered in the differential diagnosis of low back pain.

“…Consistent with the possible congenital origin of these lesions, intrasacral meningocele may occur in association with other anomalies like sacral vertebral anomalies, 11 diastematomyelia, 8 or tethered spinal cord. 3,6,8,12 There have been previous case reports of associated thickened filum 3,6 and lumbar disc prolapse.…”

Object Intrasacral meningoceles are rare cystic lesions that can cause focal compression within the bony sacral canal. Their mechanisms are poorly understood, but most intrasacral meningoceles appear to be intrasacral extradural cysts caused by arachnoid herniating through a small dural defect in the caudal end of the thecal sac. As opposed to perineural cysts, they are not associated with an exiting nerve root. When symptomatic, they can cause sacral pain or sacral nerve root dysfunction due to local compression. Methods This is a retrospective series from Boston Children's Hospital. All patients in whom symptomatic intrasacral meningocele that required surgical treatment was diagnosed between May 1994 and March 2011 were included in the study. Spine MRI was the diagnostic modality of choice. All patients underwent sacral exploration, with ligation and obliteration of the cyst. Resected cyst wall was subjected to pathological examination. Results There were 13 patients (11 boys and 2 girls) who underwent operation for intrasacral meningocele. The median age was 8 years (range 5 months–16 years). The most common presenting symptom was back pain (in 5) often described as deep tail bone pain, followed by urinary incontinence (3) and constipation (2). Three patients had evidence of associated tethered cord on MRI studies. Four patients were asymptomatic and their diagnosis was made following imaging for other reasons; they were surgically treated because of the increasing size of the lesion or association with other congenital lesions. Most patients had symptomatic improvement after surgery. Conclusions Intrasacral meningoceles are rare lesions that may result from a congenital dural weakness and a resultant arachnoid diverticulum. They present in childhood either incidentally or with symptoms secondary to nerve root compression. Identification of the point of herniation through the dura mater and ligation of the lesion provides cyst cure and resolution of symptoms in most patients.
