Objective Meningioma consistency is important because it affects the difficulty of surgery. To predict preoperative consistency, several methods have been proposed; however, they lack objectivity and reproducibility. We propose a new method for prediction based on tumor to cerebellar peduncle T2-weighted imaging intensity (TCTI) ratios. Design The magnetic(More)
Rathke cleft cysts (RCCs) are benign cystic lesions of the sella that arise from the remnants of Rathke pouch. Although most are asymptomatic, symptoms can result from mass effect and commonly include headache, endocrinopathy, or visual field disturbance. Although asymptomatic patients undergo conservative treatment, patients with symptoms are typically(More)
BACKGROUND Thoracic splenosis is a rare entity. It occurs sometime after splenic and diaphragmatic injury, and it is rarely symptomatic. CASE DESCRIPTION We report a case of left upper thoracic paraspinal splenosis 25 years after a thoracoabdominal penetrating trauma that required a splenectomy. The pathology was suspected on a routine chest x-ray and it(More)
BACKGROUND Failed back surgery syndrome (FBSS) is a condition in which there is failure to improve satisfactorily after back surgery. It is characterized by intractable pain and various degrees of functional disability after lumbar spine surgery. It is estimated that this complication occurs in 5% to 10% of patients after spinal surgeries. The major causes(More)
OBJECT A Glasgow Coma Scale (GCS) score of 3 on presentation in patients with severe traumatic brain injury due to blunt trauma has been recognized as a bad prognostic factor. The reported mortality rate in these patients is very high, even approaching 100% in the presence of fixed and dilated pupils in some series. Consequently, there is often a tendency(More)
OBJECT Authors of several studies have implied a key role of glutamate, an excitatory amino acid, in the pathophysiology of traumatic brain injury (TBI). However, the place of glutamate measurement in clinical practice and its impact on the management of TBI has yet to be elucidated. The authors' objective in the present study was to evaluate glutamate(More)
OBJECT Prediction of outcome from initial presentation after a gunshot wound to the head (GSWH) is essential to further clinical decision making. The authors' goals are to report the survival and functional outcomes of these patients, to identify prognostic factors, and to propose a scoring system that can predict their outcome. METHODS The records of 199(More)
Objective Pituitary adenomas are typically soft. The prevalence of fibrous adenomas is ∼ 5 to 13%. Firm tumors are difficult to remove by curettage or suction. Predicting fibrous adenomas by magnetic resonance (MR) imaging is typically difficult and unreliable. We propose a new prediction method based on MR T2-sequence intensity. Methods The MRIs of 36(More)
Spontaneous subdural haematoma is very rare in young patients. The complications of anabolic steroid intake in weight lifters are numerous, yet subdural haematomas have not been reported. We report on two cases of spontaneous subdural haematomas in young weight lifters. Both patients underwent surgical evacuation and made a full recovery. A review of the(More)
