It was postulated that the balloons, containing contrast medium of increased osmolarity compared to serum, had increased in size on scan and lowering serum osmolarity cleared the palsies with decrease in the size of the balloons.

Hoyt, Department of Neurological Surgery, clo Editorial Office, 1360 Ninth Avenue, Suite 210, San Francisco, CA 94122.] The authors report magnetic resonance imaging characteristics in four patients with neurofibromatosis 1 and optic nerve glioma, which they believe may be typical of optic nerve gliomas in this disease.

Box 2916, Pediatric HematologyOncology, Duke University Medical Center, Durham, NC 27710.] The authors report three children, aged 8 years, 14 weeks, and 2 years, who presented with optic pathway glioma. Two had leptomeningeal metastases at onset; one developed these after surgical biopsy and radiation therapy. Although a grave complication, the authors note that leptomeningeal metastases are rare with these tumors. Lyn A. Sedwick, M. D.

Pearson, Department of Ophthalmology, University of Kentucky, 801 Rose Street, Lexington, KY 40536- 0223. ] Following left retrobulbar injection for cataract surgery, the patient had uncontrolled shivering and subsequent total ophthalmoparesis of the other eye, which resolved in 1 hour. The authors discuss why they think this probably resulted from inadvertent orbital vein injection and secondary involvement of the cavernous sinuses. LYl1 A. Sedwick, M. D. |
