Endoscopic management of posterior fossa arachnoid cyst in an adult: case report and technical note.

The authors report a case of large arachnoid cysts of the posterior fossa treated by endoscopic surgery. A 40-year-old man was admitted with a 3-month history of headache and progressive gait imbalance, with no significant medical history. At the time of admission, neurological examination revealed no abnormalities except for tandem imbalance.

Terminal syringomyelia mimicking an intramedullary tumor: case report.

In this report, the authors present a 14-year-old male patient admitted with progressive paraparesis and urinary incontinence that developed in a 3-month period. Thoracolumbar MRI revealed an intramedullary lesion starting from the level of the T10 vertebra and extending to fill the sacral spinal canal. Based on the radiological findings an intramedullary tumor was suspected.

Acute traumatic orbital encephalocele related to orbital roof fracture: reconstruction by using porous polyethylene.

A case report of acute traumatic orbital encephalocele related to orbital roof fracture and its management were presented. Acute traumatic encephalocele related to orbital roof fracture is unusual. Early diagnosis and treatment are very important since the raised intraorbital pressure may irreversibly damage the optic nerve.

Altered cyclin D1 genotype distribution in human sporadic pituitary adenomas.

Background: The cyclin D1 gene (CCND1) is a proto-oncogene playing a critical role in the transition through the G1 to the S phase of the cell cycle and is overexpressed in many tumors. G870A polymorphism at the exon4/intron4 splicing region of the CCND1 gene may play a role in pituitary tumorigenesis and invasiveness. The objective of this study was to examine CCND1 polymorphism in patients with different types of sporadic pituitary adenomas.
