Interhemispheric subdural hematoma.

Although relatively uncommon, interhemispheric subdural hematoma (ISDH) occurs more frequently than was suspected before the advent of computerized tomographic (CT) scanning. When its mass is sufficiently large to compress the medial cerebral hemisphere, specific focal neurological abnormalities may occur. These include weakness of the contralateral leg, or contralateral hemiparesis with the leg being weaker than the arm. On the unenhanced CT scan ISDH is seen as a crescent shaped, midline hyperdensity. Treatment is dictated by the clinical course. Evacuation of the hematoma by parasagittal craniotomy is recommended if the symptoms are pronounced.

Peridurography with metrizamide: animal and human studies.

Metrizamide (300 mg l/ml) was tested for spinal peridurography in conscious dogs and humans. Epidural metrizamide was non-irritating in volumes up to 12 ml. Larger volumes caused mild discomfort in two patients. Radiographic contrast was satisfactory, and there were no sequelae. Peridurography with metrizamide (300 mg l/ml) appears to be a safe, useful diagnostic procedure in ambulant patients.

Traumatic central retinal vein occlusion.

A patient with the clinical picture of thrombosis of the central retinal vein following relatively minor head trauma is discussed. Only 2 reports in the literature have documented a similar event. It is suggested that the condition may have arisen as a result of an abnormality of the central retinal venous outflow system since such an abnormal pattern was discovered on orbital venography.
