1/55. Inferior division third nerve paresis from an orbital dural arteriovenous malformation.Isolated inferior division third nerve palsies are rare. The authors report a patient with an isolated, pupil-involving inferior division third cranial nerve palsy from an intraorbital dural arteriovenous malformation. Despite spontaneous thrombosis of the malformation, the third nerve palsy persisted. To the authors' knowledge, this is the first case report of an inferior division third nerve palsy caused by an orbital dural arteriovenous malformation.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
2/55. exophthalmos and epidural hematoma.The development of a right exophthalmos in a patient with a left hemispheric epidural hematoma is reported. The parallel development of these two conditions in this unusual case suggests some direct relationship, although it must be recognized that a coincidental relationship is possible. The exact cause of the exophthalmos remains obscure.- - - - - - - - - - ranking = 0.83333333333333keywords = dura (Clic here for more details about this article) |
3/55. radiation response of Rosai-Dorfman disease presenting with involvement of the orbits.The purpose of this study was to review an interesting case of recurrent orbital sinus histiocytosis. The patient initially failed surgery, chemotherapy, and steroid therapy, only to have a durable response to low-dose radiation therapy of the orbits, lasting 6 and 11 years, respectively. Because there are few documented responses to radiotherapy, we present a case report in conjunction with the clinical, radiographic, and histopathologic information as well as a literature review of similar cases.- - - - - - - - - - ranking = 0.16666666666667keywords = dura (Clic here for more details about this article) |
4/55. Ophthalmologic outcome of transvenous embolization of spontaneous carotid-cavernous fistulas: a preliminary report.We give a preliminary report of the ophthalmologic outcome of four patients with transvenous embolization studied for their spontaneous carotid-cavernous fistulas. One of them is a direct type while three of them are indirect dural shunts. In indirect dural shunts, traditional transarterial embolization rarely achieves a complete clinical cure in a short period of time. All cases had an ophthalmologic disturbance justified for endovascular intervention. We performed catheterization, and subsequently embolization with Guglielmi Detachable coils, to the cavernous sinus via the femoral vein and inferior petrosal sinus/superior ophthalmic vein. All four patients achieved clinical and angiographic improvement with a follow-up period range from two to sixteen months except for one patient who had residual bilateral sixth nerve palsy. The transvenous approach offers an effective and safe alternative for the management of spontaneous carotid-cavernous fistula.- - - - - - - - - - ranking = 0.33333333333333keywords = dura (Clic here for more details about this article) |
5/55. Unilateral proptosis and chemosis caused by dural arteriovenous malformation of the superior sagittal sinus.We describe a patient with unilateral proptosis and chemosis resulting from a dural arteriovenous malformation (AVM) of the superior sagittal sinus (SSS) fed mainly by branches of both external carotid arteries. The symptoms may have been caused by increased SSS pressure and disturbance of venous flow by the dural AVM.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
6/55. Meningeal solitary fibrous tumor as an unusual cause of expohthalmos: case report and review of the literature.OBJECTIVE AND IMPORTANCE: We report an extremely rare case of a patient with meningeal solitary fibrous tumor with orbital involvement presenting as unilateral exophthalmos. This rare tumor should be considered in the differential diagnosis for aggressive dural-based lesions. CLINICAL PRESENTATION: A 54-year-old man presented with a protruded eyeball on the right side and left hemiparesis. Computed tomography and magnetic resonance imaging demonstrated a huge mass, markedly enhanced in and around the right anterior clinoid process, which extended to the orbit and middle cranial fossa. cerebral angiography revealed a richly vascular tumor fed by branches of both the right external and internal carotid arteries. A presumptive diagnosis of meningioma or hemangiopericytoma was considered. INTERVENTION: The tumor was exposed through an orbitozygomatic approach. At surgery, the tumor was grossly firm to hard and had destroyed the dura, orbital roof, anterior clinoid process, temporal bone, and muscle. Histological analysis revealed that the tumor was composed of spindle-cell proliferation in a collagen-rich background, but it exhibited regional variations. The vascular network demonstrated irregular vascular lumina with a "hemangiopericytoma-like" pattern. Histological features included high cellularity and a high degree of pleomorphism. Immunohistochemical analysis of the tumor demonstrated diffuse positive staining for CD34 and vimentin. The tumor displayed no positive staining for cytokeratin, epithelial membrane antigen, glial fibrillary antigenic protein, S-100 protein, and factor xiii. CONCLUSION: Meningeal solitary fibrous tumor is considered a unique pathological entity. Wider use of immunohistochemical screening should enable analysis of the real incidence of these tumors; larger series and longer follow-up duration will allow conclusions to be drawn regarding treatment and prognosis. Differential diagnosis is discussed and the literature is reviewed.- - - - - - - - - - ranking = 0.5keywords = dura (Clic here for more details about this article) |
7/55. Rosai-Dorfman disease presenting with isolated bilateral orbital masses: report of two cases.Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) is a rare benign idiopathic proliferative disease of phagocytic histiocytes. Approximately 80% of patients present with painless massive cervical lymphadenopathy. Isolated extranodal involvement is relatively uncommon. Two cases of Rosai-Dorfman disease are reported: one with isolated bilateral orbital involvement and one with marked cervical lymphadenopathy and multiple dural-based and intraventricular masses.- - - - - - - - - - ranking = 0.16666666666667keywords = dura (Clic here for more details about this article) |
8/55. Unilateral proptosis and intracranial schwannoma.Two cases of unilateral proptosis associated with intracranial schwannomas in children are described. In both cases, tumour occupied both the orbit and middle cranial fossa, where in one case the intracranial component was extradural and in the other intracerebral. Possible sites of tumour origin are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = dura (Clic here for more details about this article) |
9/55. Growing fractures of the orbital roof. A report of two cases and a review.Growing fractures rarely arise in the skull base. Only six cases of orbital roof growing fractures were found in the relevant literature. We report two such cases. The first case was a 2-year-old girl who had progressive proptosis for 6 months following a mild head injury 1 year previously. The second case was a 9-year-old girl with a history of injury at the age of 3 months. She developed eye deviation and proptosis for 1 year. Computed tomography scan is excellent for demonstrating bony defects in the orbital roof, while magnetic resonance imaging is more sensitive in showing the intraorbital extension of a leptomeningeal cyst. Both patients were operated successfully and proptosis disappeared postoperatively. The exact pathophysiology of growing fractures is still debated in the literature, but a dural laceration along a fracture line is noted in all cases, and frontobasal brain injury seems to play an important role in the pathogenesis of the fracture growth. Growing fractures of the orbital roof should be suspected if ocular symptoms appear in a child who had sustained a head injury several months or years before.- - - - - - - - - - ranking = 0.16666666666667keywords = dura (Clic here for more details about this article) |
10/55. Ocular scrofuloderma with unilateral proptosis.Proptosis due to an extraconal orbital abscess of tubercular origin with lacrimal gland involvement, representing ocular scrofuloderma, is a rare entity. This association has not been reported earlier in the literature. We describe a 7-year-old boy who presented with nodulo-ulcerative lesions of tubercular etiology with discharging sinuses on right side of the face and a similar lesion on the right lower eyelid along with proptosis of 4 months duration. Computerized tomography (CT) scan of the head confirmed the extraconal, intraorbital, hyperdense, homogeneously enhancing mass separated from the lateral rectus muscle and further revealed involvement of lacrimal gland along with erosion of the temporal bone. The patient showed marked improvement of his dermatological and ophthalmological lesions with anti-tubercular treatment. Subsequent ultrasound examinations of the orbit revealed regression in the size of the abscess from 10.7 mm to 5.0 mm and then complete disappearance of the abscess obviating surgical intervention.- - - - - - - - - - ranking = 0.16666666666667keywords = dura (Clic here for more details about this article) |
