Presentation
Pre-operative assessment for bilateral dysplastic hips requiring arthroplasty
Patient Data
Well defined, rounded defect in the lower sacrum with a huge fluid collection in the pelvis communicating with the spinal thecal sac - typical of a sacral meningocoele. No solid component to indicate myelomengiocoele but note bilateral dysplastic hip joints and advanced osteoarthritis on the right suggesting that gait/muscle strength has always been abnormal due to some degree of neurological deficit.
MRI confirms the CT findings indicating that the huge fluid collection in the pelvis is connected to the thecal sac and is not the bladder or other pathological cyst.
Case Discussion
As is seen in this case, anterior meningocoeles (without a myelo component) can be asymptomatic.
