RETINAL CAPILLARY HEMANGIOBLASTOMA (RCH): A CASE REPORT.

Introdução / Purpose

Retinal capillary hemangioblastoma (RCH) is a slow-growing, highly vascularized benign tumor. Corresponds to about 1 to 2% of primary central nervous system tumors. About 25% are associated with Von-Hippel-Lindau Syndrome.

Material e Método / Methods

This is a retrospective case chart review study, patient treated in 2021, at the Governor Celso Ramos hospital, in Florianópolis-SC.

Resultados / Results

A 34 year-old woman, previously healthy, complained of visual loss in the left eye (OS) for 3 months. Ophthalmological examination: visual Acuity (VA) in the right eye (OD) 20/20 and OS 20/30, no pupillary defect. The anterior segment and intraocular pressure had no significant findings in both eyes. The fundus examination did not reveal any alterations in OD; but OS revealed: optic disc with well-delimited edges, superior temporal damage with vasonutrition and exudative retinal detachment. B-scan ultrasound revealed an image suggestive of superior and inferior temporal exudate and ainferior temporal lesion measuring 1.87mm in height . Diagnostic hypotheses of hemangioblastoma in OS were proposed. We referred the patient to the ocular oncology department due to the possibility of association with other tumors.

Discussão e Conclusões / Conclusion

Diagnosis of Retinal capillary hemangioblastoma is mainly clinical by funduscopic evaluation. There are several forms of treatment, such as clinical observation, laser photocoagulation, radiotherapy, cryotherapy and vitrectomy depending on the size and location of the tumor. The clinical case described is consistent with the classic findings in the literature, and the initial approach adopted was observation, since at the moment the lesion is stable, with no signs of vitreous hemorrhage or significant low visual acuity. The patient was referred to the clinical oncology department due to the possibility that the hemangioblastoma was associated with other tumors, such as pheochromocytoma and renal tumor.
