Development of early cerebral swelling in surgically treated ruptured aneurysm of acute stage, its significance, and management.

The present study includes 38 patients treated surgically for ruptured aneurysm manifesting subarachnoid hemorrhage without intracerebral hematoma, evaluating clinical grade at admission, secondary development and management of early cerebral swelling, subsequent complications such as cerebral infarction caused by vasospasm, and clinical outcome. Six of 32 patients treated by early surgery within 24 hours developed critical cerebral swelling in the early period after SAH. Five of these 6 patients received barbiturate therapy.

Correlation between diffusion-tensor magnetic resonance imaging and motor-evoked potential in chronic severe diffuse axonal injury.

We conducted a study to evaluate the degree of corticospinal tract (CST) dysfunction associated with diffuse axonal injury (DAI) through analyses of both diffusion-tensor magnetic resonance imaging (DTMRI) and motor-evoked potential (MEP). Using DTMRI and MEP with transcranial magnetic stimulation, we evaluated 138 instances of CST in 52 patients with severe chronic DAI and compared them with the findings in 17 normal volunteers. We determined values of fractional anisotropy (FA) on FA maps obtained with DTMRI of six regions of interest (ROIs) in the CST, consisting of the semioval center, coronal radiation, posterior limb of internal capsule, midbrain, pons and medulla oblongata.

[Invasive cerebral aspergillosis in an immunocompetent patient: a case report].

A 32-year-old immunocompetent female presented with sensory aphasia and psychomotor seizure due to aspergillosis in the left temporal lobe spreaded from the left orbita. In spite of oral administration of itraconazole, the symptoms continued to deteriorate due to extension of the lesion to the left temporoparietal white matter. As a result of the stereotactic biopsy of the lesion, she was histologically diagnosed as intracerebral aspergillosis.
