Whereas, posteriorly growth is due to interstitial growth at spheno-occipital synchondrosis.Cranial base center, sella turcica, forms anterior limb (from sella to nasion) and posterior limb (from sella to basion) of cranial base; forming an angle of 130o - 135o at sella.
This allows to safely approach the sella turcica, optic nerve, tuberculum sella and planum sphenoidale for surgeons, in some lesions including skull base lesions and cerebrospinal fluid leaks (Wiebracth & Zimmer).
(1) The pituitary gland is located at the base of the brain in the sella turcica (pituitary fossa) of the sphenoid bone.
There were also bony and dural changes along the anterior skull base with erosion of the sella turcica and lateral sphenoid bone toward the cavernous sinus (Figure 1).
A CT scan of the head demonstrated a large mixed-density sellar/suprasellar mass with expansion of the sella turcica (Figure 1) and erosion of the dorsum sellae.
(TNA = transnasal approach (surgical route of access); A = anterior; R = right; F = frontal sinus; ST = sella turcica; S = superior.)
This endonasal transsphenoidal endoscopy eliminates needs of sublabial or transseptal incision, use of any transsphenoidal retractor and nasal packing.2 The transsphenoidal approach for resection of a pituitary adenoma was first performed by Herman Schloffer more than 100 years ago.3 When compared to the techniques that utilize microscopes, endoscopic surgery permits a wider field of vision, better visualization of the supra and parasellar region and of the neurovascular structures (optic nerves, chiasm, carotid artery, and cavernous sinus).4 The introduction of the endoscope in the sella turcica brings to light the structures and the normal tissue/tumor interface thus facilitating the removal of tumor remains.
(1) In this case report I will discuss the history, examination and conclusions in a 27-year-old woman whose chronic symptoms were compatible with ICH, yet had a negative LPOP as well as normal sella turcica and cerebral cisterns.

The magnetic resonance imaging (MRI) of the brain revealed a 31x25x22 mm cystic mass lesion with contrast enhancement that filled the sella turcica and appeared isointense with cerebrospinal fluid in the T1A and T2A sequences and hyperintense in fluid attenuation inversion recovery (FLAIR) sequences and showed contrast enhancement in postcontrast images (Figures 1).
The wound course involved base of the skull with a narrow hole in the skull, about 2 x 0,3 cm in size, just on the right side of sella turcica. On the right side of the brain stem two slightly deformed pellets were found.
At the age of four, pneumatisation of the sphenoid bone progresses and by seven years it reaches the floor of the sella turcica in most of the cases.
