Anterior sacral meningocele in a patient with Marfan syndrome.

Anterior sacral meningocele has been reported to be associated with Marfan syndrome (MFS) in few cases, differently from dural ectasia appearing up to two thirds of affected patients. A new instance of this association is described in an 18-year-old man with Marfan syndrome, diagnosed upon MRI morphological evaluation which showed a huge cystic mass in the pelvic space. Surgical excision even if curative was not performed in consideration of a stationary picture after one year since diagnosis.
