Computed tomography with giant intracranial aneurysms.

Five patients with giant intracranial aneurysms were studied by computed tomography. Secondary intracranial changes such as hemorrhage, cerebral infarction and communicating hydrocephalus are easily demonstrated by computed tomography. In addition, computed tomography provides precise information concerning the actual size and location of large but partially thrombosed or calcified aneurysm to better advantage than angiography.

Experimentally induced cerebral aneurysms in rats.

Saccular cerebral aneurysms were successfully induced in rats treated with beta-aminopropionitrile, deoxycorticosterone and salt hypertension and ligation of unilateral common carotid artery. This experiment was performed on the hypothesis that if hemodynamic stresses were increased on the fragile, cerebral arterial wall of beta-aminopropionitrile-fed animals, cerebral aneurysms might be produced. Although the incidence of cerebral aneurysms was low and the contributory mechanisms of these procedures must be more clearly elucidated, the present results show that saccular cerebral aneurysms are really inducible in experimental animals.

Computed tomography in the differential diagnosis of low-density intracranial lesions.

Computed tomographic (CT) findings of low-density lesions of the brain were compared with the pathologic nature of the lesions. Twenty-one lesions having densities uniformly lower than those of the normal brain, most of which showing no significant early enhancement effect, were selected. Such lesions were either cystic non-neoplastic lesions, cystic tumors, solid tumors or solid but non-neoplastic lesions. Although CT proved to be the single, most sensitive diagnostic method detecting such low-density lesions, it was often difficult or even impossible to differentiate cystic from solid, or neoplastic from non-neoplastic lesions based on the CT features alone.
