1/200. Bilateral optic disk edema caused by sarcoidosis mimicking pseudotumor cerebri.PURPOSE: To present a case of retrobulbar optic nerve and chiasm sarcoidosis that mimicked pseudotumor cerebri. methods: A 34-year-old, thin, black woman presented with transient visual obscurations, normal visual acuity, bilateral optic disk edema, and enlarged blind spots. Clinical, medical, and radiologic evaluations were consistent with pseudotumor cerebri. The patient improved while taking acetazolamide, but 6 months later her symptoms worsened. neuroimaging disclosed enhancement of the optic nerve and chiasm. RESULTS: Despite administration of intravenous corticosteroids, the patient's vision worsened. Bilateral optic nerve sheath fenestrations were performed, and pathology disclosed sarcoidosis. CONCLUSION: sarcoidosis of the optic nerves and chiasm may mimic pseudotumor cerebri.- - - - - - - - - - ranking = 1keywords = disk edema, optic, disk, edema (Clic here for more details about this article) |
2/200. pseudotumor cerebri: an unusual complication of brachiocephalic vein thrombosis associated with hemodialysis catheters.We report a case of pseudotumor cerebri (PC) in a maintenance hemodialysis patient that was associated with thrombosis of the right and left brachiocephalic veins caused by repeated subclavian and jugular vein catheterizations. Symptoms and signs of PC appeared when a right forearm Gortex graft was inserted. PC secondary to intracranial venous outflow obstruction is an important diagnostic consideration for hemodialysis patients with headache, visual disturbance, and papilledema.- - - - - - - - - - ranking = 0.97236041797558keywords = papilledema, edema (Clic here for more details about this article) |
3/200. Unilateral papilledema after bone marrow transplantation.We describe a patient who developed unilateral papilledema after allogeneic BMT. This is a rare manifestation of pseudotumor cerebri, which results from elevated intracranial pressure caused by cyclosporin A. The papilledema usually involves the fundi bilaterally, but unilateral involvement has been described. Congenital anomalies, compression and adhesion of the optic nerve sheath are its causes. In this patient, the right optic fundus was spared although leukemic infiltration was present on this side and high-dose irradiation (72 Gy) was given. Although papilledema is a sensitive marker of elevated intracranial pressure, this sign may be masked by constriction of the optic sheath in patients who suffer from leukemic infiltration of the central nervous system and receive high doses of cranial irradiation.- - - - - - - - - - ranking = 6.8333149063547keywords = papilledema, optic, edema (Clic here for more details about this article) |
4/200. pseudotumor cerebri in children receiving recombinant human growth hormone.PURPOSE: This article represents the first report in the ophthalmology literature of an association between pseudotumor cerebri (PTC) and recombinant human growth hormone (rhGH). DESIGN: Noncomparative case series. PARTICIPANTS: Three children receiving rhGH for short stature with turner syndrome, Jeune syndrome, or down syndrome. methods: Children underwent full ocular examination. After papilledema was identified, patients underwent lumbar puncture and imaging with either magnetic resonance imaging or computerized tomography. Treatment was under the guidance of the primary physician or neurosurgeon. The rhGH was discontinued in all children. MAIN OUTCOME MEASURES: visual acuity and evaluation of the optic nerve for resolution of papilledema were followed at each examination. RESULTS: In all three cases, papilledema resolved with the cessation of rhGH, and treatment with acetazolamide or prednisone. visual acuity was unchanged in case 1, decreased by two to three lines in case 2, and was inconsistent in case 3. One child (case 2) required a ventriculoperitoneal shunt for persistent elevation of intracranial pressure. CONCLUSION: There appears to be a causal relationship between the initiation of rhGH with the development of PTC. Children should have a complete ophthalmic evaluation if they report headache or visual disturbances. Baseline examination with routine follow-up should be instituted when children cannot adequately communicate.- - - - - - - - - - ranking = 2.926011914102keywords = papilledema, optic, edema (Clic here for more details about this article) |
5/200. Retropharyngeal rhabdomyosarcoma mimicking pseudotumor cerebri.A 6-year-old male presented with headache, vomiting, visual obscuration, and papilledema. Clinical presentation, initial laboratory data, and radiologic evaluation suggested a diagnosis of pseudotumor cerebri. The development of lower cranial nerve palsies after transient resolution of symptoms prompted reassessment of the diagnosis, which revealed retropharyngeal rhabdomyosarcoma involving the right jugular vein. cerebral angiography demonstrated the complete venous occlusion at the jugular foramen. Careful neurologic follow-up is essential in a patient with pseudotumor cerebri or idiopathic intracranial hypertension.- - - - - - - - - - ranking = 0.97236041797558keywords = papilledema, edema (Clic here for more details about this article) |
6/200. Dural sinus thrombosis and pseudotumor cerebri: unexpected complications of suboccipital craniotomy and translabyrinthine craniectomy.OBJECT: The goal of this study was to document the hazards associated with pseudotumor cerebri resulting from transverse sinus thrombosis after tumor resection. Dural sinus thrombosis is a rare and potentially serious complication of suboccipital craniotomy and translabyrinthine craniectomy. pseudotumor cerebri may occur when venous hypertension develops secondary to outflow obstruction. Previous research indicates that occlusion of a single transverse sinus is well tolerated when the contralateral sinus remains patent. methods: The authors report the results in five of a total of 107 patients who underwent suboccipital craniotomy or translabyrinthine craniectomy for resection of a tumor. Postoperatively, these patients developed headache, visual obscuration, and florid papilledema as a result of increased intracranial pressure (ICP). In each patient, the transverse sinus on the treated side was thrombosed; patency of the contralateral sinus was confirmed on magnetic resonance (MR) imaging. Four patients required lumboperitoneal or ventriculoperitoneal shunts and one required medical treatment for increased ICP. All five patients regained their baseline neurological function after treatment. Techniques used to avoid thrombosis during surgery are discussed. CONCLUSIONS: First, the status of the transverse and sigmoid sinuses should be documented using MR venography before patients undergo posterior fossa surgery. Second, thrombosis of a transverse or sigmoid sinus may not be tolerated even if the sinus is nondominant; vision-threatening pseudotumor cerebri may result. Third, MR venography is a reliable, noninvasive means of evaluating the venous sinuses. Fourth, if the diagnosis is made shortly after thrombosis, then direct endovascular thrombolysis with urokinase may be a therapeutic option. If the presentation is delayed, then ophthalmological complications of pseudotumor cerebri can be avoided by administration of a combination of acetazolamide, dexamethasone, lumbar puncture, and possibly lumboperitoneal shunt placement.- - - - - - - - - - ranking = 0.97236041797558keywords = papilledema, edema (Clic here for more details about this article) |
7/200. Syndrome simulating pseudotumor cerebri caused by partial transverse venous sinus obstruction in metastatic prostate cancer.PURPOSE: To report a case of partial transverse venous sinus obstruction causing a syndrome resembling pseudotumor cerebri. METHOD: Case report. A 61-year-old man developed decreased vision, bilateral papilledema, and a highly increased cerebrospinal fluid opening pressure. brain magnetic resonance imaging (MRI) disclosed a small, extra-axial mass near the torcula, which was dismissed as an incidental meningioma because cerebral angiography showed sinus patency. RESULTS: The patient's vision worsened. biopsy of the enlarging mass disclosed metastatic prostate cancer. After radiation therapy, the mass shrank, magnetic resonance angiography disclosed reopening of the transverse sinuses, and papilledema resolved, but visual fields remained severely compromised. CONCLUSION: Partial blockage of the dural venous sinus by a small mass near the torcula can cause a sufficient increase in intracranial pressure to produce vision-threatening papilledema.- - - - - - - - - - ranking = 2.9170812539268keywords = papilledema, edema (Clic here for more details about this article) |
8/200. recurrence of idiopathic intracranial hypertension after weight loss: the carrot craver.PURPOSE: To describe a patient with stable idiopathic intracranial hypertension whose papilledema worsened. METHOD: Case report. RESULTS: A patient with documented idiopathic intracranial hypertension had resolution of disc edema with weight loss. recurrence of papilledema led to the discovery that she consumed large quantities of raw carrots to help maintain her weight. Her increased vitamin a levels normalized, and the disc edema resolved when she stopped eating carrots. CONCLUSION: patients with idiopathic intracranial hypertension should be counseled regarding carrot intake.- - - - - - - - - - ranking = 1.9449056452452keywords = papilledema, edema (Clic here for more details about this article) |
9/200. pseudotumor cerebri caused by all-trans-retinoic acid: a case report.pseudotumor cerebri is a condition characterized by increased intracranial pressure with normal cerebrospinal fluid composition. It is usually associated with many medical conditions and drugs. It has been reported that all-trans-retinoic acid can induce pseudotumor cerebri. The authors report a 35-year-old patient diagnosed with acute promyelocytic leukemia who developed pseudotumor cerebri after receiving all-trans-retinoic acid. The patient was treated with 60 mg/day of all-trans-retinoic acid. Two weeks later, she had severe headache and blurred vision. The neurological examination revealed papilledema and decreased visual acuity. Other physical examinations were unremarkable. brain CT was normal. Additionally, lumbar puncture was performed and the CSF finding was normal except for high CSF pressure. According to modified Dandy criteria, the diagnosis was pseudotumor cerebri. The patient's symptoms disappeared after all-trans-retinoic acid was discontinued. To our knowledge, this is the first case report in thailand.- - - - - - - - - - ranking = 0.97236041797558keywords = papilledema, edema (Clic here for more details about this article) |
10/200. Headaches and papilledema secondary to dural arteriovenous malformation.A 21-year-old developed progressive headaches and pulsatile tinnitus. He was found to have papilledema and a pulsatile bruit. A dural arteriovenous malformation was not recognized on brain CT or MRI, but was well documented on magnetic resonance angiography and cerebral angiography. Dural malformations draining into the superior sagittal sinus can cause increased intracranial venous pressure and secondarily increase intracranial pressure even without a mass effect.- - - - - - - - - - ranking = 4.8618020898779keywords = papilledema, edema (Clic here for more details about this article) |
