Show 148 LITERATURE ABSTRACTS Magnetic Resonance Imaging of Pituitary Stalk Hypoplasia: A Discrete Midline Anomaly Associated with Endocrine Abnormalities in Septo- optic Dysplasia. Kaufman LM, Miller MT, Mafee MF. Arch Ophthalmol1989; 107: 1485- 9 ( Oct). [ Reprint requests to Dr. L. M. Kaufman, Department of Ophthalmology, University of illinois at Chicago, College of Medicine, 1855 W. Taylor St., Chicago, IL 60612.] A 20- month- old and 25- month- old infant are described, both of whom demonstrated optic nerve hypoplasia, endocrine abnormalities, and lack of pituitary stalk on magnetic resonance scanning. The authors believe these patients represent part of a continuum of septic- optic dysplasia syndromes that they would like to rename " suprasellar dysplasia." Lyn A. Sedwick, M. D. Malignant Rhabdoid Tumor of the Orbit. Rootman J, Damji KF, Dimmick JE. Ophthalmology 1989; 96: 1650-- 4 ( Nov). [ Reprint requests to Dr. J. Rootman, 2550 Willow Street, Vancouver, B. C., Canada V5Z 3N9.] A 6- week- old infant with progressive proptosis starting at 1V2 weeks of age was found to have a primary malignant rhabdoid tumor of the orbit. Extensive histologic specimens, some in color, are presented and described. Lyn A. Sedwick, M. D. Ocular Involvement in Castleman's Disease. Gittinger JW Jr. Ophthalmology 1989; 96: 1646- 9 ( Nov). [ Reprint requests to Dr. J. W. Gittinger, Jr., Room S7- 834, University of Massachusetts Medical Center, 55 Lake Avenue N., Worcester, MA 01655.] A 21- year- old man with Castleman's disease and infiltration of the left disk and choroid, with exophthalmos as well, is described who responded to orbital radiation therapy. He had an intracranial abnormality on computerized tomographic scanning which spontaneously regressed. This entity is briefly discussed. Lyn A. Sedwick, M. D. ' I' Advances in Magentic Resonance Imaging. Jay WM. Am , Ophthalmol 1989; 108: 592- 6 ( Nov). [ Reprint requests to Dr. W. M. Jay, Department of Ophthalmology, Loyola University, 2160 S. First Avenue, Maywood, IL 60153.] Walter Jay gives a nice concise review of current techniques of magnetic resonance imaging, particularly relating to orbit. Several good magnetic resonance pictures are included. Lyn A. Sedwick, M. D. Invasive Sinonasal Polyps Causing Ophthalmoplegia, Exophthalmos, and Visual Field Loss. Kaufman LM, Folk ER, Chow JM. Ophthalmology 1989; 96: 1667- 72 ( Nov). [ Reprint requests to Dr. L. M. Kaufman, Department of Ophthalmology, University of Illinois College of Medicine at Chicago, 1855 West Taylor Street, Chicago, IL 60612.] A 20- year- old man with a history of recurrent sinonasal polyps requiring six polypectomies developed bilateral ophthalmoplegia, exophthalmus, and visual field loss. Polyps were found to be invasive into orbits and cavernous sinuses. Decompressive surgery was performed and all ocular findings improved. Lyn A. Sedwick, M. D. Orbital Nonchromaffin Paraganglioma: A Case Report and Review of the Literature. Archer KF, Hurwitz JJ, Balogh JM, Fernandes BJ. Ophthalmology 1989; 96: 1659- 66 ( Nov). [ Reprint requests to Dr. K. F. Archer, 5022 Holly, Corpus Christi, TX 78411.] A 24- year- old man with a previous presumed glomus jugulare tumor after inconclusive biopsy presented 14 years later with an orbital mass found to be a nonchromaffin paraganglioma. Previously reported cases involving the orbit are reviewed. Lyn A. Sedwick, M. D. |
