Desprendimiento neurosensorial macular recurrente en fístula carótido-cavernosa / Recurrent neurosensory macular detachment in carotid-cavernous fistula

RESUMEN

CASO CLÍNICO: Varón de 46 años, acudió a Urgencias por disminución de agudeza visual y exoftalmos en ojo derecho. Aquejaba cefalea, diplopía de 4 meses de evolución e historia de desprendimiento neurosensorial (DNS) resuelto espontáneamente un mes antes. Presentaba tortuosidad de vasos conjuntivales y epiesclerales y nuevo DNS macular derecho. La sospecha de fístula carótido-cavernosa quedó confirmada mediante angiotomografía computarizada (angio-TC). Durante su ingreso la fístula se cerró espontáneamente. Al mes, el DNS había desaparecido. DISCUSIÓN: La fístula carótido-cavernosa debe incluirse en el diagnóstico diferencial de los DNS maculares. El DNS puede desaparecer espontáneamente al cerrarse la fístula

ABSTRACT

CASE REPORT: A 46 year-old man was seen in the emergency department complaining of vision loss and exophthalmos in his right eye. He also complained of headache, diplopia of 4 months onset, and neurosensory detachment that resolved spontaneously the month before. The study revealed tortuous conjunctival and episcleral vessels and neurosensory macular detachment in his right eye. A carotid-cavernous fistula was confirmed by computed tomography angiography. The fistula closed spontaneously during the hospitalization. One month later, the neurosensory detachment disappeared again. DISCUSSION: Carotid-cavernous fistula should be included in the differential diagnosis of neurosensory macular detachments. These neurosensory detachments can resolve spontaneously 11 the fistula is closed
