A rare case of nervous tumor of the neck is presented. Differential diagnosis is evoked in the discussion. A total removal of the tumor is to be realized with or without nerve reconstruction.
The age factor is analysed for the operative indication in old patients. For the authors, operative indications are depended of mental and general status, clinical grade (I or II), localization and anatomical conformation of the aneurysm. The operation is performed only if the patient is asymptomatic or three weeks after the onset of the subarachnoid hemorrage. The peroperative hypotension is prohibited.
The authors report a case of loss of mental imagery in a 35 year old male patient who was operated on for an intraventricular meningioma in the region of the left trigonum collaterale. The symptomatology and its evolution are described. Discussion of the pathophysiologic hypotheses is focused on the possible role of a selective memory disturbance, of a functional disconnection between language- and visual representation-areas of the brain, and of visual agnosia. In the reported case, the underlying pathophysiologic mechanism seems to be very close to the one responsible for visual agnosia, and could be explained as a partial dissolution of visual memories. Analysis of 35 cases of loss of mental imagery reported in the literature shows that the investigation of this peculiar disturbance is in many cases incomplete. It nevertheless reveals that visual agnosia, or a particular form of visual agnosia, is present in all cases of unilateral posterior lesion of the dominant hemisphere.
Five cases of spontaneous cerebellar hematomas are reported. In four cases the diagnosis was made by computerized tomography. The clinical diagnosis being difficult, surgical treatment was often applied too late and the diagnosis sometimes never made. Systematic use of computerized tomography should allow earlier treatment of this type of lesion, the clinical evolution determining the prognosis. (Acta neurol. bels., 1980, 80, 73-79).
Twelve patients with intraventricular hematomas were treated only with continuous ventricular drainage combined with intracranial pressure monitoring. Half of the patients showed a favourable clinical response. The main interest of ventricular drainage lies in the treatment of acute hydrocephaly which is usually associated.
