Epidermoid cyst (EC) or cholesteatoma is a benign tumor, often of congenital origin, occurring in the sub-arachnoidian spaces. Its treatment is based on surgery. We report the case of a 38 year-old patient presenting with progressive intracranial hypertension syndrome associated with anterior pituitary insufficiency signs of the corticotropic, thyrotropic, gonadotropic axis occurring 1 year before. Brain MRI showed a craniopharyngioma. Anatomopathologic evaluation of the specimen showed epidermoid cyst.

BACKGROUND: Glioblastomas in the sellar region are very rare; in most cases, the tumor originates from the optic nerve/optic chiasm. Only 4 cases of sellar glioblastoma with a non-optic origin have been reported. We present such a case with detailed clinical, imaging and histopathological information. A review of similar published cases is also presented. CASE PRESENTATION: A 42-year-old woman presented with endocrinological abnormalities including, amenorrhea and lactation, symptoms of diabetes insipidus and signs of elevated ICP...

Woo Shik Jeong, Hyung Hwa Jeong, Soon Man Kwon, Kyung S Koh, Jong Woo Choi
BACKGROUND: The conventional approach during orthognathic surgery for cleft-related deformities has largely focused on restoration of maxilla retrusion, using the maxillary advancement as a standard treatment objective. However, we thought the maxillary vertical shortening and deficient incisor show could be the additional key elements of cleft-related deformities. Although slight vertical lengthening can be obtained with only maxillary advancement, it would not be enough to obtain satisfactory aesthetical results in terms of the anterior facial height...

BACKGROUND: Craniopharyngioma (CP) adherence represents a heterogeneous pathological feature that critically influences the potentially safe and radical resection. OBJECTIVE: To define the MRI predictors of CP adherence severity. METHODS: This study retrospectively investigated a cohort of 200 surgically treated CPs with their corresponding preoperative conventional MRI scans. MRI findings related to the distortions of anatomical structures along the sella turcica-third ventricle axis caused by CPs, in addition to the tumor's shape and calcifications were analyzed and correlated with the definitive type of CP adherence observed during the surgical procedures...

OBJECT: In the past decade, the endonasal transsphenoidal approach (eTSA) has become an alternative to the microsurgical transcranial approach (mTCA) for tuberculum sellae meningiomas (TSMs) and olfactory groove meningiomas (OGMs). The aim of this meta-analysis was to evaluate which approach offered the best surgical outcomes. METHODS: A systematic review of the literature from 2004 and meta-analysis were conducted in accordance with the PRISMA guidelines. Pooled incidence was calculated for gross total resection (GTR), visual improvement, cerebrospinal fluid (CSF) leak, intraoperative arterial injury, and mortality, comparing eTSA and mTCA, with p-interaction values...

OBJECTIVE The expanded endonasal endoscopic transsphenoidal approach has become increasingly used for craniopharyngioma surgery in the pediatric population, but questions still persist regarding its utility in younger children, in recurrent and irradiated tumors, and in masses primarily located in the suprasellar region. The narrow corridor, incomplete pneumatization, and fear of hypothalamic injury have traditionally relegated this approach to application in older children with mostly cystic craniopharyngiomas centered in the sella...

Detection of incidental intracranial aneurysm on neuroimaging can be associated with pituitary adenoma; however, such association is extremely rare. However, aneurysm with extension into the sella is extremely rare, and increases the risk of inadvertent intraoperative rupture, if trans-sphenoidal decompression is attempted either using endoscopic or microscopic surgical approach. Hanak et al. in a literature review of intrasellar noniatrogenic aneurysms over PubMed search in 2012 could only collect 31 studies, of which only eight cases had pituitary adenoma associated with aneurysm extending into sella...

Manuela Cerbone, Mehul T Dattani
Growth hormone deficiency (GHD) can present at any time of life from the neonatal period to adulthood, as a result of congenital or acquired insults. It can present as an isolated problem (IGHD) or in combination with other pituitary hormone deficiencies (CPHD). Pituitary deficits can evolve at any time from GHD diagnosis. The number, severity and timing of occurrence of additional endocrinopathies are highly variable. The risk of progression from IGHD to CPHD in children varies depending on the etiology (idiopathic vs organic)...

Thoracic endovascular aortic repair (TEVAR) has undergone rapid evolution and is now applied to a range of aortic pathologies. Imaging plays a vital role in the pre- and postintervention assessment of TEVAR patients. Accurate characterization of pathology and evaluation for high-risk anatomic features are necessary in the planning phase, and careful assessment for graft stability, aortic lumen diameter, and presence of endoleak are paramount in the follow-up period. CTA is the imaging modality of choice for pre- and postintervention assessment, and MRA is an acceptable alternative depending on patient stability and graft composition...

PURPOSE OF REVIEW: To summarize the literature on dysphotopsia, focusing on strategies for management and prevention. RECENT FINDINGS: Clinical studies and ray-tracing diagrams have improved our understanding of the risk factors for positive and negative dysphotopsiae. Well known management and prevention strategies such as piggyback IOL, reverse optic capture, Nd:YAG capsulotomy, and IOL exchange are reviewed, as well as newer strategies such as the infertemporal approach to IOL implantation, 'in-the-bag nasal optic truncation' and new IOL design implantation, and new IOL design...

Noniatrogenic pituitary abscesses remain a rare clinical entity, and are the indication for surgery in <1% of transsphenoidal approaches. Correct diagnosis of this rare entity is often delayed. Without timely treatment, morbidity and mortality are high. Of the 200 cases reported, less than half have identified a causative organism. We report the second case of a pituitary abscess caused by Candida species, and further provide intraoperative video of endoscopic management of this pathology. A 33-year-old woman presented with headache, hypopituitarism, and vision loss in the setting of diabetic ketoacidosis, and was found to have multiple abscesses in the liver, lung, kidney, and uterus...

Imagery plays an important role in our life. Motor imagery is the mental simulation of a motor act without overt motor output. Previous studies have documented the effect of motor imagery practice. However, its translational potential for patients as well as for athletes, musicians and other groups, depends largely on the transfer from mental practice to overt physical performance. We used bilateral transcranial direct current stimulation (tDCS) over sensorimotor areas to modulate neural lateralization patterns induced by unilateral mental motor imagery and the performance of a physical motor task...
