Three cases of mixed internal and external carotid-cavernous fistula (CCF) were successfully treated with embolization of feeders from the external carotid artery (ECA) and focal irradiation to the cavernous sinus (CS). Cases 1 and 2 were females, 63 and 69 years old respectively, both with spontaneous left CCF. Case 3 was a 55 year old male with posttraumatic left CCF. Symptoms of case 1 were double vision, left chemosis and exophthalmos; those of case 2 were double vision, left retroobital pain, left forehead dysesthesia and blurred vision; and case 3 complained of double vision, left chemosis, left exophthalmos and pulsatile tinnitus. In all three cases, angiography disclosed left CCF fed by ipsilateral dural branches from the internal maxillary artery (IMA) and the internal carotid artery (ICA). In case 1, small branches from the ascending pharyngeal artery also fed the CS. In cases 2 and 3, feeders from the ECA were arising only from branches of the IMA. In case 3, hypertrophy of the meningohypophyseal trunk was visible. In cases 1 and 2, although the CS was opacified, feeders from the ICA were not clearly visible. Embolizations of branches of the IMA were performed in all cases using Ivalon under selective catheterization. In case 1, symptoms partially improved, but in cases 2 and 3, visual symptoms were transiently aggravated. Focal irradiation to the CS was done with total doses of 30, 30 and 40 Gy each for cases 1, 2, and 3 respectively. In case 1, clinical symptoms gradually improved about one third way through irradiation.(ABSTRACT TRUNCATED AT 250 WORDS)

An unusual case of bilateral blindness secondary to a cavernous sinus thrombosis is reported. A woman who had undergone reconstructive surgery after tumor resection of the floor of the mouth, was readmitted 1 month later with bilateral proptosis and signs of sepsis. There were no complaints of blurred vision. A CT-scan of the orbits demonstrated a bilateral cavernous sinus thrombosis (CST) secondary to an infection at the skull base behind the myocutaneous flap. A few days later she became blind, due to bilateral central retinal artery occlusion and anterior ischemic optic neuropathy. The general critical condition improved with intensive AB treatment. The patient recovered well without neurological defects apart from her permanent bilateral blindness. There were no signs of tumor recurrence. To our knowledge, this is the first documented case of bilateral blindness in a patient suffering from CST.

A 66-year-old white male presented with complaints of redness of his left eye, blurred vision, lid edema, and an intermittent throbbing pain above his left eye for 4 days. Significant clinical findings included mild hyperemia and edema of the left upper lid, marked engorgement and tortuosity of the conjunctival and episcleral vessels, mild chemosis, and extreme limitation of the extraocular movements of the left eye in all directions of gaze, especially adduction. This eye also showed a measurable proptosis with positive retropulsion. Pupillary responses and color vision were normal in both eyes. A CT scan revealed an enlarged medial rectus muscle, including its tendinous insertion with a normal cavernous sinus. On the basis of the clinical findings and the CT scan, a diagnosis of orbital pseudotumor was made. The patient was treated with high dose systemic prednisone, which resulted in a dramatic improvement of symptoms and signs.

A 27-year-old women with chondrosarcoma of the ethmoid sinus extending to the anterior fossa had initial symptoms of blurred vision on the left and slight proptosis. Neuroradiological examination, however, disclosed that the tumor extended not only to the anterior cranial fossa, but also to the orbit, nasal cavity, and maxillary sinus. It is difficult to predict the biological behavior of chondrosarcoma by means of histological examination. The effectiveness of radiotherapy, chemotherapy, or both is also a matter of controversy. Clinical aspects of chondrosarcoma are briefly discussed.

In a retrospective survey of patients taking medication for hyperlipidaemia, those taking niacin (nicotinic acid) were more likely (p < 0.05) to report sicca syndromes, blurred vision, eyelid oedema, and macular oedema compared with those who never took niacin. Additionally, 7% of those taking niacin discontinued the drug owing to adverse ocular side effects, while none of the other lipid lowering agents were found to cause these side effects (p = 0.016). Data from spontaneous reporting systems support a possible association of decreased vision, cystoid macular oedema, sicca-like symptoms, discoloration of the eyelids with or without periorbital or eyelid oedema, proptosis, loss of eyebrow or eyelashes, and superficial punctate keratitis with the use of niacin in high doses. Decreased vision may be marked, and if the drug is not discontinued, may progress to cystoid macular oedema. All ocular side effects listed above are reversible if the association with niacin is recognised and the drug is discontinued; both the incidence and severity of the ocular side effects seem to be dose dependent.

Among incident cases of GO in Olmsted County, Minnesota: GO affected females six times more frequently than males (86% versus 14% of cases, respectively). The age-adjusted incidence rate was 16 cases per 100,000 population per year for females and 2.9 cases per 100,000 population for males. The peak incidence rates were bimodal, occurring in the age groups 40 to 44 years and 60 to 64 years in females and 45 to 49 years and 65 to 69 years in males. Among patients with GO, approximately 90% had Graves' hyperthyroidism, 1% had primary hypothyroidism, 3% had Hashimoto's thyroiditis, and 5% were euthyroid. Eyelid retraction was the most common ophthalmic feature of autoimmune thyroid disease, being present either unilaterally or bilaterally in more than 90% of patients at some point in their clinical course. Exophthalmos of one or both eyes affected approximately 60% of patients, restrictive extraocular myopathy was apparent in about 40% of patients, and optic nerve dysfunction occurred in either one or both eyes in 6% of patients with autoimmune thyroid disease. Only 5% of patients had the complete constellation of classic findings: eyelid retraction, exophthalmos, optic nerve dysfunction, extraocular muscle involvement, and hyperthyroidism. Upper eyelid retraction, either unilateral or bilateral, was documented in approximately 75% of patients at the time of diagnosis of GO. Lid lag also was a frequent early sign, being present either unilaterally or bilaterally in 50% of patients at the initial examination. At the time of diagnosis of GO, the most frequent ocular symptom was pain or discomfort, which affected 30% of patients. Some degree of diplopia was noted by approximately 17% of patients, lacrimation or photophobia was present in about 15% to 20% of patients, and 7.5% of patients complained of blurred vision. Decreased vision attributable to optic neuropathy was present in less than 2% of eyes at the time of diagnosis of GO. Thyroid dermopathy and acropachy accompanied GO in approximately 4% and 1% of patients, respectively. Myasthenia gravis occurred in less than 1% of patients. Superior limbic keratoconjunctivitis was documented in less than 4% of patients. The median age at the time of diagnosis of GO was 43 years (range, 8 to 88). Among patients with hyperthyroidism, 61% developed ophthalmopathy within 1 year of the onset of thyrotoxicosis. Symptoms and signs for which statistically significant changes occurred between the initial and final examinations included lacrimation, pain or ocular discomfort, photophobia, eyelid retraction, lid lag, eyelid fullness, conjunctival injection, chemosis, and exophthalmos.(ABSTRACT TRUNCATED AT 400 WORDS)

A surgical case of monostotic fibrous dysplasia of the left frontal and sphenoidal bone in a 14-year-old girl is described. This girl was admitted to our hospital in March, 1992, with a chief complaint of facial deformity and asymmetry due to a painless and progressive bony bulging over the left fronto-orbital region. But she denied any symptoms such as proptosis, diplopia, optic atrophy and visual loss. Other data found on neurological examination and laboratory tests were normal. In addition, she had no history of skin lesions, precocious puberty or other endocrine abnormalities. Plain craniogram showed remarkable thickening of the left frontal bone and of the anterior cranial fossa of the sphenoidal bone with irregular stenosis of the left optic canal. CT scan showed the diffuse enlargement of the affected bone and involvement of the paranasal sinuses. Angiography revealed no positive findings. On December 10, 1992, orbito-cranial reconstruction and unilateral optic canal release were performed using an extradural approach through a left fronto-temporal craniectomy. Histological findings confirmed the lesion to be typical fibrous dysplasia. She recovered completely one month after the operation, but she suffered transient blurred vision, diplopia and left ptosis. Most of the decreased vision caused by fibrous dysplasia cannot be reversed after surgical treatment. So, if optic canal stenosis is evident, even when visual loss is not clear, release of the optic canal stenosis should be done as early as possible in association with experienced neurosurgeons and with meticulous dissection.

We report a case of multiple meningioma associated with intraosseous and tentorial meningioma. A 75-year-old woman was admitted to our hospital with blurred vision and exophthalmos in the left eye. Left lower hemianopsia, deterioration of visual acuity and right cerebellar signs were found on neurological examination. CT and MR image revealed an intraosseous tumor of the left sphenoid bone and a right tentorial mass. Cytogenetic analysis failed to reveal any abnormalities of chromosome 22. The intraosseous tumor which was transitional type meningioma and the tentorial mass, which was a fibroblastic meningioma were successfully excised. Postoperatively, the patient's symptoms and signs improved. Intraosseous meningioma associated with multiple meningioma is extremely rare and the histogenesis of meningioma arising from ectopic arachnoid cells is discussed.

An 8-year-old girl had acute onset of blurred vision, proptosis, and lateral and vertical gaze palsies on the right. CT and MR examinations showed an expansile mass involving the greater wing of the right sphenoid bone. Pathologic analysis of the surgical specimen revealed a capillary hemangioma. The lesion was inhomogeneous but predominantly isointense with gray matter on T1-weighted images. On T2-weighted images the lesion was inhomogeneous with areas of both high and low signal intensity. The rim enhanced uniformly, and there was inhomogeneous enhancement of the bulk of the lesion.

A 39-year-old man had bilateral proptosis and blurred vision for I week. Computed tomography and magnetic resonance imaging showed signs of bilateral orbital pseudotumor, a suprasellar mass, and pulmonary infiltration. Biopsies from retrobulbar and bronchial sites showed similar inflammatory tissue. His disease resolved with pulsed corticosteroid therapy.
