ABSTRACT
PURPOSE: To report a rare case of isolated intraconal meningioma. CASE REPORT: A 24-year-old woman presented with painless proptosis in her left eye which started and progressed during her pregnancy about 10 months ago. Hertel exophthalomometry revealed anterior displacement of the globe with 4 mm of proptosis which was remarkable. Magnetic resonance imaging (MRI) demonstrated an intraconal circumscribed oval-shaped mass with hypointense signals on T1-weighted images and hyperintense signals on T2-weighted images, mimicking cavernous hemangioma. This mass, however, was free of any connections to optic nerve or bones. Due to the imaging characteristics, more prevalent diagnoses like cavernous hemangioma were placed on the top of the differential diagnoses list. However, during the surgical excision, the tumor's consistency and gross features were not compatible with cavernous hemangioma. The pathologic findings instead determined meningotheliomatous meningioma, a very rare condition, which was far from our expectations prior to the surgery. CONCLUSION: Ectopic orbital meningiomas are rare tumors that are not easily diagnosed without postoperative histopathology. Despite its low prevalence, they should be considered in the differential diagnosis list of intraconal masses with hypointense signals on T1-weighted images and hyperintense signals on T2-weighted images.
ABSTRACT
BACKGROUND: High prevalence of ocular surface disorders includes eye dryness and corneal ulcer among intensive care unit patients remains an issue. This study aimed to compare the effectiveness of Lubratex ointment and vitamin A eye ointment in preventing ocular surface disorders in intensive care unit patients. METHODS: A single-center randomized clinical trial was conducted in critically ill patients of vitamin A eye ointment and Lubratex ointment in preventing ocular surface disorders. Forty-one eligible patients were randomly assigned to administered vitamin A eye ointment in one eye and Lubratex ointment in the other eye. After five days, using fluorescein and Schirmer's tests, an ophthalmologist examined patients and specified those with ocular surface disorders. RESULTS: The results showed a significant decrease in the incidence of dry eye (p ≤ 0.001) and corneal ulcer (p = 0.002) with the use of Lubratex ointment. CONCLUSIONS: Although Lubratex ointment was more effective than vitamin A ointment in preventing ocular surface disorders, further research is needed to confirm the findings of the present study.
ABSTRACT
PURPOSE: To present a patient with giant cell tumor (GCT) of the orbit by changing behavior from an intraorbital mass to an intraosseous tumor. METHODS: A 16-year-old boy presented with pain, swelling, erythematous of the left upper and lower eyelids, proptosis, and diplopia. Ophthalmic examination revealed chemosis, conjunctival injection, limited elevation, depression as well as abduction in the left eye. RESULTS: Multislice computed tomography scan (CT scan) of the orbit and paranasal sinuses showed a hyperdense, oval, extraconal mass with bone erosion. Magnetic resonance imaging of the orbit showed an inferior lateral isointense, oval, extraconal mass that had indented the globe. The patient underwent superior lateral orbitotomy, and the orbital mass was excised. Two months later, the patient developed proptosis, severe chemosis, and eyelid erythema in the same eye. CT scan showed an intraosseous mass in the lateral wall of the orbit that had pushed the globe anteromedially. Intraosseous tumor was resected, and the lateral orbital wall was drilled during the second surgery. GCT was diagnosed based on pathological survey. CONCLUSION: Following the resection of the orbital GCT, the tumor behavior may change to an intraosseous lesion.
