INTRODUCTION The prevalence of neural tube defects worldwide is 1 - 2 per 1000 neonates. Neural tube defects result from a disturbance of neurulation in the 3rd or 4th week of development and thus represent the earliest manifestation of organ malformation. Neural tube defects (NTD) are classified into cranial dysraphism leading to anencephaly or meningoencephalocele and spinal dysraphism with o...

Malformations of the spine and spinal cord are common in domestic mammals. Among these, syringomyelia is defined as a cystic, fluid filled tubular cavity (syrinx) within the spinal cord extending over several segments. Syringomyelia occurs as a primary congenital malformation and is most commonly combined with neural tube defects. However, it can also be acquired after alterations in cerebrospi...

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 lev...

Although pediatric neurosurgery is relatively young as a formal subspecialty of general neurosurgery (the first meeting of the Section of Pediatric Neurological Surgery was held in 1972 and the American Society of Pediatric Neurosurgery first met in 1978), it has been practiced for millennia. Trephined pediatric skulls were excavated in Peru and at other ancient sites.1 The father of neurosurge...

Meningeal solitary fibrous tumor (SFT) is a rare tumor and is different from fibroblastic meningiomas (FM) and hemangiopericytoma (HPC). SFTs account for 0.09% of all meningeal tumors.[1-3] Compared to meningiomas the SFTs show a predilection for the posterior fossa and spine.[1,2] Most of these tumors are benign, however, local recurrence have been reported.[3] Gengler and Guillou[4] in a revi...
