In a simplistic and succinct way, Liliequist membrane may be understood as a projection formed by an arachnoid membrane extending from the dorsum sellae to the mammillary bodies. In spite of being well known to neurosurgeons, many radiologists neither know this anatomical structure nor give importance to its study. The imaging evaluation of this membrane is feasible and may be interesting for a...

A prospective study assessed the size and frequency of visualization of the normal pituitary stalk on high-resolution computed tomography (CT). The normal pituitary stalk can be seen on the vast majority of high-resolution scans obtained with thin sections and intravenous contrast material. The upper size limit of the normal pituitary stalk is 4 mm at the level of the dorsum sellae and 4.5 mm a...

Gorlin-Goltz syndrome is a rare autosomal dominant disorder that involves multiple organ systems, including the skin, skeleton and jaws. We report a case of young female with multiple odontogenic keratocysts, high arched palate, euryopia, palmer pits, solitary, pigmented nevus , areas of hyper-pigmentation in the upper eyelid of left eye, dorsal surface of hands, calcified diaphragma sellae, ri...

some patients was lateralised (fig 1) or could be seen as a narrow cleft. A tumour in the remaining tissue in a partially empty sella could also be defined, allowing us to identify four tumours in partially empty sellae and in one patient (case 12) to remove the tumour selectively, leaving the normal pituitary tissue and function undisturbed. Other features of value that were clearly visualised...

With the refinement in biomedical gadgetry, it has been a modern day requisite to safeguard indigenous neuro-architecture and henceforth foretell postoperative neurological outcome. The intraoperative neuro-physiological monitoring (IONM) comes as no surprise be only credible paradigm which can cluethe standing of neural pathway directly during general anesthesia. By engaging with IONM applianc...

The transsphenoidal transplanum, transtuberculum approach to the suprasellar cistern, also called the “extended” transsphenoidal approach, has been used during the past 10 years by experienced transsphenoidal surgeons to remove a limited number of well-circumscribed suprasellar lesions (7, 8, 10, 17, 20–23, 29). Initially, a sublabial approach was generally used and visualization was provided w...

BACKGROUND AND PURPOSE High signal intensity (HSI) at the pituitary stalk is reported in pituitary adenomas. Our purpose was to clarify how and when this HSI formed, its long-term fate, and its relation to the function of infundibuloneurohypophyseal (INH) system. METHODS Twenty-two patients with pituitary adenoma and supradiaphragmatic extension underwent 1.5-T MR imaging. Patients were assig...
