Cat optic nerve imaging with metrizamide.
نویسندگان
چکیده
Metrizamide is a water-soluble, nonionic radiocontrast medium that penetrates better into narrow subarachnoid spaces than do oily contrast media or gas. We performed metrizamide optic nerve thecography on five cats with iatrogenic orbital lesions. Optic thecograms successfully demonstrated displacement of the optic nerve, obstruction of the optic nerve sheath subarachnoid space, and extravasation of the contrast medium from a punctured optic nerve sheath. Metrizamide-induced seizures could be prevented by intramuscular preadministration of diazepam.

متن کاملOptic neuropathy secondary to cat scratch disease: distinguishing MR imaging features from other types of optic neuropathies.
BACKGROUND AND PURPOSE MR imaging characteristics of optic neuropathy caused by cat scratch disease have not yet been described; this lack of information may result in incorrect diagnosis and may contribute to initiation of inappropriate therapy. Our study was based on the hypothesis that cat scratch disease-related optic neuropathy has distinct MR imaging features compared with those of other ...

متن کاملCT cisternography of dolichoectatic arterial compression of the optic chiasm.
Dolichoectasia of the distal internal carotid arteries and the proximal anterior cerebral arteries is a well recognized abnormality. The angiographic and computed tomographic (CT) findings have been described [1-8]. Arterial enlargement has been implicated in chiasmal and optic nerve syndromes [1, 3-9]. We report a symptomatic patient with chiasmal deformity and associated arterial dolichoectas...
