RESUMO
CASI CLÍNICO: Varón de 33 años con síndrome de Parinaud, exotropía y atrofia óptica del OI postpapiledema. Tras las pruebas de neuroimagen y biopsia estereotáxica se diagnostica de germinoma pineal. Recibe quimio y radioterapia con respuesta completa del tumor. El síndrome de Parinaud persiste un año después del diagnóstico, y rechaza la corrección del estrabismo. DISCUSIÓN: El síndrome de Parinaud consiste en una parálisis supranuclear de la mirada vertical por daño deltectum mesencefálico. El compromiso de las estructuras adyacentes da lugar al síndrome de Parinaud «plus». Ante un síndrome de Parinaud acompañado de diplopía (síndrome de Parinaud «plus») se debe pensar en la extensión de la lesión a otras áreas adyacentes
CLINICAL CASE: A 33-year-old male diagnosed with Parinaud's syndrome, exotropia and post-papillary oedema optic atrophy in his left eye. A pineal germinoma was diagnosed after performing neuroimaging scans and a stereotactic biopsy. He was treated with chemotherapy and radiotherapy, showing a complete pathological response. The Parinaud's syndrome persists one year after diagnosis and the patient has refused to have strabismus surgery. DISCUSSION: Parinaud's syndrome consists of a supranuclear vertical gaze palsy resulting from damage to the midbrain tectum. The involvement of adjacent structures leads to the «Parinaud-plus» syndrome. When a Parinaud's syndrome is accompanied by diplopia («Parinaud-plus» syndrome), extension of the injury into adjacent areas must be considered

CLINICAL CASE: A 33-year-old male diagnosed with Parinaud's syndrome, exotropia and post-papillary oedema optic atrophy in his left eye. A pineal germinoma was diagnosed after performing neuroimaging scans and a stereotactic biopsy. He was treated with chemotherapy and radiotherapy, showing a complete pathological response. The Parinaud's syndrome persists one year after diagnosis and the patient has refused to have strabismus surgery. DISCUSSION: Parinaud's syndrome consists of a supranuclear vertical gaze palsy resulting from damage to the midbrain tectum. The involvement of adjacent structures leads to the «Parinaud-plus¼ syndrome. When a Parinaud's syndrome is accompanied by diplopia («Parinaud-plus¼ syndrome), extension of the injury into adjacent areas must be considered.
