Intrinsic third ventricle craniopharyngiomas with normal pressure hydrocephalus.
No full textTwo observations of intrinsic third ventricle craniopharyngiomas, both involving males in the fifth decade, are reported. Histologically, the tumours, one entirely solid and the other one chiefly cystic, were composed of squamous epithelium with microcysts and no calcifications. In the literature primary third ventricle craniopharyngiomas are considered to be exceedingly rare. However, if a more precise preoperative diagnosis, using computerised axial tomography, were made as a matter of routine, to verify third ventricular masses, it might demonstrate that these tumours are more common than previously believed. In both cases striking clinical pictures of normal pressure hydrocephalus were observed. The relations between intracranial pressure, CSF circulation and ventricular size are discussed. On mechanical grounds, it is very difficult to explain the poastoperative reduction in ventricular size, since there was no significant change in intracranial pressure
Mass lesions of the frontal lobes in acute head injuries. A comparison with temporal lesions.
No full textContusions and lacerations of the frontal lobes are very frequent; 43.4% in the whole series of traumatic brain mass lesions. Clinical ICP, CT scan data and neuropathological findings in patients with such lesions are analysed and correlated. Moreover, the clinical features and the outcome of frontal masses undergoing surgery are also compared with similar lesions located in the temporal lobes. Frontal lesions cannot be differentiated on purely clinical grounds and the factors governing the outcome in both lactations are the same. On the whole, surgical indications nowadays seem to be rather rare; only lesions behaving truly as expanding lesions with obvious intracranial hypertension benefiting from surgery. Brain contusion-laceration syndromes in general can no longer be considered separate entities. Neither should they be included in the miscellaneous group of "traumatic intracranial mass lesions", since the pathophysiological significance of purely extracerebral effusions is entirely different. Traumatic contusions and lacerations and/or intracerebral haematomas, whether frontal or located elsewhere, should instead, be considered in the context of head injuries of a different degree of gravity, as having collateral features which, on occasion, may call for surgical management
The reliability of computerized axial tomography in the diagnosis of infratentorial mass lesions. A neurosurgical appraisal.
No full textTraumatic cerebral mass lesions: correlations between clinical, intracranial pressure, and computed tomographic data.
No full textAfter surveying the different phases of their previous experience with the diagnosis and management of traumatic cerebral mass lesions, the authors analyze the correlation between clinical, computed tomographic (CT), and intracranial pressure (ICP) data in 29 patients with traumatic intracerebral hematomas and/or brain lacerations. Clinically, the patients are classified in three groups: (a) deeply comatose patients (Glascow coma scale (GCS), 4 to 5); (b) patients with intermediate disturbances of consciousness (GCS, 6 to 10); and (c) patients with minor impairment of consciousness (GCS, more than 10). Sixteen patients were operated upon. Operation was ineffective in the patients who were already deeply comatose in the first hours after injury, even though elevated ICP was definitely reduced after operation in some of them. Conversely, patients with well-limited lesions, moderate disorders of consciousness, and persisting intracranial hypertension despite medical therapy seemed to be good candidates for delayed operation by limited procedures. In patients with intermediate disturbances of consciousness and no tendency to improvement or deterioration, ICP monitoring correlated with CT scan appearance may be of practical use for making the decision to operate. However, most cases diagnosed on CT scan have a benign course; the patients recover uneventfully with conservative management. In such patients careful clinical observation is usually sufficient
