Coexistence of idiopathic intracranial hypertension and optic disc drusen in a latin american patient: case report.

Optic nerve drusen are acellular concretions of calcium located in the parenchyma of the optical nerve head described as the most common cause of pseudo-papilloedema, which makes it difficult to differentiate from a true optical disc oedema. Despite it being rare, the drusen of the optic nerve and the papilloedema secondary to idiopathic intracranial hypertension can coexist in the same patient. The case is presented of a 34 year-old woman referred to the Ophthalmology Department with visual discomfort, headaches, and pulsatile tinnitus of two months onset. In the physical examination there was bilateral blurring of the optic disc margin with absence of spontaneous venous pulsation. The diagnosis of idiopathic intracranial hypertension was made by lumbar puncture with the measurement of the opening pressure, and due to the findings of the magnetic resonance scan of the brain and the eye sockets. The optic nerve drusen was an incidental finding in an optical coherence tomography angiography, which would later be confirmed with an eye ultrasound. To our knowledge, this the first case reported in Latin America of the coexistence of optic nerve drusen and papilloedema secondary to idiopathic intracranial hypertension.

Síndrome de Susac completo en un hombre de 22 años en Colombia: a propósito de un caso y revisión de la literatura / Complete Susac syndrome in a 22-year old male in Colombia: Case report and a review of the literatura

Presentamos el caso de un joven de 22 años con 4 meses de cefalea, hipoacusia y disminución de la visión izquierdos. Su madre refirió además cambios del comportamiento y del estado de ánimo. La resonancia magnética cerebral mostró múltiples lesiones hiperintensas en la rodilla del cuerpo calloso. La audiometría documentó una hipoacusia neurosensorial. En la oftalmoscopia se observó un infarto retiniano de la capa de fibras nerviosas en el ojo izquierdo, el cual fue confirmado con una tomografía de coherencia óptica; la angiografía fluoresceínica mostró múltiples focos de hiperfluorescencia de la pared de las arteriolas, defectos del llenado de las arteriolas, y regiones focales de isquemia de la coroides. Estos hallazgos confirman el diagnóstico presuntivo de un síndrome de Susac. Este es uno de los pocos casos publicados en la literatura de un síndrome de Susac en un hombre joven con la tríada diagnóstica completa, y el primero en Colombia

We report the case of a 22 year-old male with a clinical picture of 4 months onset of headaches, deafness, and a decrease of vision in the left eye. His mother mentioned he also had changes in behaviour and mood. The magnetic resonance scan of the brain showed multiple hyper-intense lesions in the knee of the corpus callosum. The hearing test reported a neurosensory deafness. In the ophthalmoscopy, a retinal infarction was observed in the nerve fibre layer in the left eye, which was confirmed using optical coherence tomography. The fluorescein angiography showed multiple foci of hyperfluorescence of the arteriole walls, arteriole filling defects, and regional ischaemia foci of the choroid. These findings confirmed the presumed diagnosis of a Susac syndrome. This is one of the few cases reported in the literature of a Susac syndrome in a young man with the complete diagnostic triad, and the first in Colombia
