RESUMO

Bilateral sight threatening macular and optic nerve inflammation may occur with dengue fever, necessitating the use of systemic steroids. We report a case of bilateral dengue maculopathy in an elderly woman managed with targeted intravitreal steroid therapy. A 63-year-old woman presented with acute-onset painless diminution of vision in both eyes following a dengue fever episode. She had bilateral foveal inflammatory lesions, macular oedema, small vessel occlusions at the macula and scattered retinal haemorrhages and cotton-wool spots. Following systemic evaluation, intravitreal triamcinolone acetonide injection was performed in both eyes at an interval of 3 days. The foveal lesion and macular oedema resolved quickly in both eyes with a normal foveal architecture at the end of 6-week follow-up. The visual acuity improved considerably in both eyes. Inflammatory retinopathy in dengue fever may be managed with a targeted intravitreal steroid injection approach.

RESUMO

We hereby report a case of metastatic Ewing's sarcoma presenting with rapid-onset total ophthalmoplegia, optic atrophy, and right temporal hemianopia. Comprehensive ophthalmic and neurological evaluation with targeted radioimaging revealed a tumor mass centered over the sella, compressing optic chiasma, extending to involve the left cavernous sinus and the left orbital apex. Whole-body imaging revealed the evidence of multifocal lung and mediastinal metastasis with focal lytic defect in the left femoral head. Histopathological evaluation of transnasal punch biopsy from the nasopharyngeal extension of the tumor revealed small round-cell tumor with strong CD99 positivity, supporting the diagnosis of Ewing's sarcoma. Rapid, aggressive extensions of the metastatic tumor into vital structures despite the initiation of chemoradiation of the extensive intracranial tumor led to unexpected demise of the patient. Our case is an unusual case of Ewing's sarcoma metastasis manifesting as a sellar mass and mimicking a pituitary adenoma radiologically, with a rapid progression within 2 weeks to cause massive extension of tumor into suprasellar, infrasellar, and left parasellar area, indicative of highly malignant nature of the tumor.
