1/109. Orbital dirofilariasis: MR findings.dirofilariasis is a helminthic zoonosis occurring in many parts of the world. We report the findings in a 61-year-old woman who had painless right exophthalmos caused by orbital dirofilariasis. A vivid worm was embedded inside an inflammatory nodule in the right orbit. On T1-weighted MR images, the parasite was visible as a discrete, low-intensity, tubular signal in the center of the nodule surrounded by contrast-enhancing inflammatory tissue.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
2/109. Lung cancer, proptosis, and decreased vision.A 48-year-old man presented to the emergency department with a 3-day history of decreased vision in a painful proptotic right eye. The patient was being treated with chemotherapy and radiation for non-small cell lung carcinoma. Examination showed visual acuity of hand motions, decreased motility, and an afferent pupillary defect on the right, consistent with an orbital apex syndrome. neuroimaging revealed "dirty" orbital fat and no paranasal sinus disease. Orbital biopsy initially showed only fibrosis; however, on subsequent biopsies, nonseptate hyphae later identified as mucormycosis was recovered. The patient survived with exenteration and systemic amphotericin b.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
3/109. Congenital intraorbital optic nerve cyst. Case report.Congenital cystic lesions of the optic nerve are exceedingly rare; only one case is reported in the world literature. The authors describe a case of congenital simple glial cyst in the intraorbital portion of the optic nerve with a brief review of the literature and comment on its histogenesis. A 45-day-old male infant was admitted to the hospital because of progressive proptosis and hypotropia in the left eye, which had been present since birth. magnetic resonance imaging of the left orbit revealed an ovoid, well-demarcated, homogeneous cystic mass in the intraconal retrobulbar area. The mass compressed the left eyeball with downward and lateral displacement. The wall of the cystic mass was very thin, and a needle puncture of the cyst released clear, colorless, watery fluid. The cystic wall was lined by loose astroglial nerve fibers with some scattered glial cells.- - - - - - - - - - ranking = 0.15514654564177keywords = area (Clic here for more details about this article) |
4/109. An unusual case: bilateral orbital varices.PURPOSE: To present a rare case of bilateral orbital varices. methods: An 18-year-old man showing bilateral orbital masses on magnetic resonance (MR) imaging was examined with color Doppler ultrasonography (US), computed tomography (CT) and digital subtraction venography. RESULTS: The presenting symptoms of the patient were pain and fullness in both orbits induced by bending forward. Ocular examination was normal with the exception of a two millimeter proptosis of both eyes during valsalva maneuver. MR imaging demonstrated bilateral retrobulbar masses, but was not diagnostic. The comparison of CT images obtained before and after valsalva maneuver revealed the diagnosis of orbital varices. color Doppler US and orbital venography demonstrated a large venous connection between the lesions and systemic circulation. CONCLUSION: Clinical presentation of orbital varices is unusual. Different radiological methods may be necessary for the confirmation of the diagnosis and demonstration of the anatomic and the dynamic features of the lesions.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
5/109. Ultrasonographically guided injection of corticosteroids for the treatment of retroseptal capillary hemangiomas in infants.PURPOSE: Injection of corticosteroids is a well-documented and successful mode of treatment for periorbital capillary hemangiomas. Because of the greater potential risk involved with retrobulbar injections, no prior study has described this treatment for tumors located behind the orbital septum. Although retroseptal intraorbital capillary hemangiomas comprise only 7% of all adnexal capillary hemangiomas, complications such as optic nerve compression or astigmatism may necessitate treatment. methods: Three patients with deep orbital hemangiomas that caused vision-threatening complications were treated with intralesional injections of triamcinolone and betamethasone. Orbital injection was performed with use of real-time ultrasonographic guidance of the needle. This technique was valuable in providing continuous, accurate, and safe advancement of the needletip in the orbit to avoid the globe and orbital walls. ultrasonography also permitted precise placement of the needle tip within the tumor and visualization of the injected material. RESULTS: Significant improvement was demonstrated in all cases on the basis of both ultrasonographic measurements and regression of clinical manifestations such as astigmatism, chemosis, proptosis, and optic nerve pallor. No complications were noted. CONCLUSION: Intralesional injection of corticosteroids to treat retroseptal and retrobulbar capillary hemangiomas was found to be a safe and effective treatment modality in our patients. Positioning of the injecting needle was guided by ultrasonography.- - - - - - - - - - ranking = 586.23193989436keywords = behind (Clic here for more details about this article) |
6/109. A sighting of orbital pseudotumor.A 39-year-old woman developed bilateral proptosis, photophobia, and pain with extraocular movements over the course of 5 days. Her findings initially were ocular pain and photophobia which progressed to periorbital edema and nasal discharge ultimately resulting in proptosis with vertical globe displacement and decreased visual acuity. She was diagnosed with corneal abrasion and sinusitis respectively during two initial emergency department visits. On her third visit to the emergency department within 4 days, she developed acute visual deficits. The patient was subsequently diagnosed with orbital pseudotumor after computed tomography scan revealed inflammation of orbital structures bilaterally.- - - - - - - - - - ranking = 2keywords = pain (Clic here for more details about this article) |
7/109. Osteogenic sarcoma and phthisis bulbi: a case report.PURPOSE: To describe a case of osteogenic sarcoma (osteosarcoma) that developed within a phthisical eye. METHOD: Case report. RESULTS: An 86-year-old woman with a 20-year history of phthisis bulbi developed pain and proptosis. Tumor was identified by computed tomography. An exenteration was performed, and osteogenic sarcoma was identified. CONCLUSION: Osteogenic sarcoma is the most common primary malignant tumor of bone. In the orbit it frequently is associated with prior irradiation for retinoblastoma. We describe the first case of osteogenic sarcoma that developed de novo from bone within a phthisical eye.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
8/109. HSV-1--induced acute retinal necrosis syndrome presenting with severe inflammatory orbitopathy, proptosis, and optic nerve involvement.OBJECTIVE: To present a unique case in which orbital inflammation, proptosis, and optic neuritis were the initial symptoms of acute retinal necrosis (ARN). The clinical presentation of ARN, as well as the currently recommended diagnostic procedures and guidelines for medical treatment of ARN, are summarized. DESIGN: Interventional case report. TESTING: polymerase chain reaction (PCR) techniques were made on the vitreous for cytomegalovirus, Epstein-Barr virus, herpes simplex virus (HSV), varicella zoster virus, and toxoplasmosis. A full laboratory evaluation was made together with HLA-typing and serologic tests measuring convalescent titers for HSV and other micro-organisms. magnetic resonance imaging scan, computed tomography (CT) scan, and fluorescein angiographic examination were performed. The patient was treated with acyclovir and oral prednisone. MAIN OUTCOME MEASURES: The patient was evaluated for initial and final visual acuity and for degree of proptosis, periocular edema, and vitreitis. RESULTS: The first symptoms and signs of ARN were eye pain, headache, proptosis, and a swollen optic nerve on CT scan. Other than increased c-reactive protein, all blood samples were normal. PCR was positive for HSV-type I in two separate vitreous biopsies. The patient had the strongly ARN-related specificity HLA-DQ7. CONCLUSIONS: This is the first report of HSV-induced ARN presenting with inflammatory orbitopathy and optic neuritis. polymerase chain reaction for HSV-1 was positive more than 4 weeks after debut of symptoms, which is a new finding. The combination of severe vitreitis and retinal whitening, with or without proptosis, should alert the clinician to the possibility of herpes infection and treatment with intravenous acyclovir started promptly.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
9/109. Weber-Christian disease presenting with proptosis: a case report.Weber-Christian disease (WCD) is a rare inflammatory disease of adipose tissue, which is characterized by painful cutaneous nodules and constitutional symptoms. Although any area of the body containing fat can be affected by WCD, the involvement of retrobulbar fat is uncommon and proptosis is a rare presenting manifestation. We report a case who presented with proptosis of the right eye which is accompanied by painful subcutaneous nodules, high fever and myalgia. Biopsies of retrobulbar tissue and suprapubic nodule showed lobular panniculitis with mixed cellular infiltration, mainly composed of histiocytes and lymphocytes. He responded well to high-dose glucocorticoid.- - - - - - - - - - ranking = 2.1551465456418keywords = pain, area (Clic here for more details about this article) |
10/109. Orbital compression syndrome after orbital extravasation of X-ray contrast material.PURPOSE: To report the orbital compression syndrome after orbital extravasation of x-ray contrast material during catheterization of the left middle meningeal artery. methods: Case report. RESULTS: A 61-year-old woman had profound loss of vision, pain, and proptosis of her left eye immediately after catheterization of the left middle meningeal artery. Computed tomography (CT) revealed that contrast material had extravasated into the orbit. Her symptoms improved with lateral canthotomy and cantholysis and resolved totally within 24 hours without the need for an orbital surgical procedure to remove the contrast material. CONCLUSION: This report describes an unusual cause of the orbital compression syndrome.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
