ABSTRACT

ABSTRACT A 33-year-old male presented to our clinic with low vision in both eyes that started during the previous week. Visual acuity was 20/63 in the right eye and 20/50 in the left eye. Fundus examination revealed signs of hypertensive retinopathy; thus, a multidisciplinary approach was adopted for the diagnosis and treatment of this patient. We consulted the nephrology and cardiology departments on this case. Upon diagnosing malignant hypertension and renal failure, the patient was put on hemodialysis. His visual acuity was 20/20 at 6 months, whereas foveal assessment on optical coherence tomography angiography revealed neither marked superficial and deep capillary density loss and foveal avascular zone enlargement nor a decrease in disc flow and radial peripapillary capillary density. Early diagnosis and treatment of malignant hypertension are critical in preventing progression of end-organ damage including the eyes. Optical coherence tomography angiography may be useful in cases when fundus fluorescein angiography is relatively contraindicated (e.g., renal failure).


RESUMO Um homem de 33 anos apresentou-se à nossa clínica com baixa visão em ambos os olhos que começou uma semana antes. A acuidade visual foi de 20/63 no olho direito e 20/50 no olho esquerdo. O exame de fundo de olho revelou sinais de retinopatia hipertensiva; então, adotou-se uma abordagem multidisciplinar para o diagnóstico e tratamento desse paciente. Consultamos os departamentos de nefrologia e cardiologia neste caso. Ao diagnosticar hipertensão maligna e insuficiência renal, o paciente foi colocado em hemodiálise. Sua acuidade visual era 20/20 aos 6 meses, enquanto a avaliação foveal com angiotomografia de coerência óptica não revelou perda de densidade capilar superficial e profunda acentuada e aumento da zona avascular foveal nem uma diminuição no fluxo de disco e na densidade capilar peripapilar radial. O diagnóstico precoce e o tratamento da hipertensão maligna são fundamentais na preveção da progressão de danos nos órgãos-alvo, incluindo os olhos. A Angiografia por tomografia de coerência óptica pode ser útil nos casos em que a angiografia com fluoresceína do fundo de olho é relativamente contraindicada (por exemplo, insuficiência renal).

ABSTRACT

El síndrome de leucoencefalopatía posterior reversible se presenta con síntomas de edema cerebral e imágenes hiperintensas en las secuencias T2 y FLAIR en la resonancia magnética (RM) de cerebro. Las lesiones típicamente comprometen la región parietooccipital, aunque también pueden tener localizaciones atípicas. Presentamos el caso de una mujer de 33 años que consultó por trastornos visuales asociados con dolor de cabeza intenso e hipertensión grave (220/140 mmHg). El examen del fondo de ojo reveló retinopatía hipertensiva grado IV y la RM mostró lesiones hiperintensas en T2 y FLAIR a nivel centropontino, bulbo y médula espinal, las cuales regresaron tras el control sostenido de la presión arterial.

The posterior reversible leukoencephalopathy syndrome presents with symptoms of cerebral edema. On magnetic resonance imaging (MRI) of the brain, hyperintensities on T2 -weighted and FLAIR sequences typically affect the parietal-occipital region; however it may also have atypical locations. We report the case of a 33 year old patient with visual disturbances associated with intense headache and severe hypertension (220/140 mmHg). The Fundus examination revealed grade IV hypertensive retinopathy, and MRI showed hyperintense lesions in T2 and FLAIR affecting the pontine center, medulla and spinal cord, which regressed after sustain blood pressure control.
