1/4. Bilateral basal ganglion haemorrhage in diabetic ketoacidotic coma: case report.

    We report bilateral oedema and haemorrhagic transformation in the basal ganglia of a 59-year old woman with severe diabetic ketoacidosis. Lack of cerebral vascular autoregulation, followed by blood-brain barrier disruption due to the so-called breakthrough mechanism is presumed to be the cause.

2/4. diffusion MRI in the postmortem brain: case report.

    Postmortem brain of a ten-month-old child was examined by MR imaging, and diffusion MR imaging at the 12th hour after death in order to disclose the cause of death. There were basal ganglion lesions indicating a mitochondrial disorder. There was a prominent difference between the ADC values of the white matter (0.28 /-0.04 x 10(-3) mm2/s) and cortex (0.42 /-0.04 x 10(-3) mm2/s), and this was statistically significant (p< 0.0001). This difference suggested that in the postmortem brain the conditions in the white matter leading to restriction of movement of water molecules are more severe than that in the cortex.

3/4. Traumatic cerebral edema relieved by stellate ganglion anesthesia.

    stellate ganglion neural blockade reverses within seconds anoxemia and edema by release of catecholamine vasoconstriction of the small arteries. The factor xii enzyme cascade is controlled by increased oxygenated arterial blood flow and a normal pH. My patient's rapid recovery reflects the effectiveness of this approach for treatment of traumatic cerebral edema. Continuing edema with its scar-forming process injures brain neuron function. A patient's level of recovery or survival requires such immediate and effective control of edema.

4/4. Gangliocytoma--magnetic resonance imaging characteristics.

    An atypical presentation of a temporal lobe gangliocytoma in an adult female with headaches is reported. Computed tomography showed a hypodense enhancing mass in the right temporal lobe with vasogenic oedema and mass effect. MRI demonstrated a well demarcated mass of low signal on T1W, intermediate signal on PDW, high signal on T2W and homogeneous enhancement on post-gadolinium scan. This case is an addition to the current literature for the characteristic MR features of a ganglion cell tumour.
