Brain-stem, middle latency and late auditory evoked potentials (BAEPs, MLAEPs and LAEPs, respectively) were recorded in a patient 2 months after removal of affecting the quadrigeminal plate. Simultaneously, MRI showed a left unilateral lesion involving the inferior colliculus, brachium colliculi and the medial geniculate body (MGB). On dichotic listening,(More)
The authors report a series of 37 cases of unruptured aneurysms, admitted and operated upon over a 5 year period (1985-1990), which represents an incidence of 18% of the total number of aneurysm patients operated upon during this period. These unruptured aneurysms were discovered in 4 types of circumstances: 1) Associated with a ruptured aneurysm but(More)
A series of 12 patients with tectal plate gliomas, is presented treated by direct surgery. Mean age was 19 years. All patients presented with signs of raised intracranial pressure and supratentorial hydrocephalus on CT scan. Diplopia was the most common local sign. CT scan and MR imaging showed 4 intrinsic, 6 exophytic, and 2 ventrally infiltrating tectal(More)
The prognostic value of the level of consciousness and the patient's age for the outcome of aneurysmal subarachnoid haemorrhage (SAH) is studied in 74 patients admitted on day (D) 0 to D3 after aneurysm rupture. For the level of consciousness three groups of patients are compared: grade I+II (alert patients), grade III+IV (drowsy patients), and grade V(More)
Both early auditory evoked potentials (BAEPs) and middle-latency auditory evoked potentials (MLAEPs), were recorded in nine patients suffering from a quadrigeminal plate tumor. These recordings were performed before surgery in six cases and after surgery in three cases. The results of these examinations were correlated with impairments of the midbrain(More)
CT scans and MR images were analyzed in 12 patients with histologically proved tectal plate gliomas. In an attempt to identify the nature of these lesions, their radiological characteristics were correlated with the histological results. In four of our patients CT scan failed to show the tumour. MR imaging demonstrated the tectal distortion in all cases.(More)
Backsourcing, defined generally as bringing services outsourced to a third party back in-house, is now a growing phenomenon. The decision to backsource has several significant implications for an organization, as it requires the organization to manage organizational change, reintegrate knowledge, and develop new capabilities and competences. Taking into(More)
The authors report the case of a patient who presented a ruptured aneurysm of the anterior communicating artery and an unruptured aneurysm of the middle cerebral artery arising at the site of a fenestration of the MCA. The fenestration was undiagnosed on the preoperative angiogram but discovered during the surgery carried out for clipping of the aneurysms.(More)
The authors present one of their cases operated on for intrinsic tectal plate glioma. The complete resection of the right inferior colliculus (I.C.) had no apparent auditory consequences. The pre- and post-operative tonal and vocal auditory tests were normal. The brain-stem auditory evoked potentials (BAEPs) and middle latency potentials (MLPs) were(More)
The management of the ruptured intracranial aneurysm (clinical grade I to IV only) is studied in a series including 140 patients admitted from 1985 through 1989, in which selected patients were submitted to early surgery and other patients were postponed for delayed surgery. The results are compared to those of an earlier series including 328 patients(More)
