RESUMO
A 43-year-old female is referred to our clinic for evaluation of an incidentally discovered unilateral papilledema in her right eye of unknown cause. She had no past ocular or medical history. Examination revealed a corrected-distance visual acuity of 20/20 in both eyes. Posterior segment examination showed an elevated right optic nerve head with blurred edges. Ultrasonography failed to reveal optic disc drusen. Visual field testing showed enlargement of the blind spot in the right eye. Magnetic resonance imaging of the brain and orbit was done and revealed enlargement of the intracanalicular and prechiasmatic part of the right optic nerve and a diagnosis of a presumed right intracanalicular optic nerve sheath meningioma was made. She was managed conservatively and several years later remains asymptomatic.
RESUMO
Pseudotumor cerebri is a relatively common pathology that is characterized by intracranial hypertension in the absence of mass lesions. It commonly affects young and obese women, and its presentation with visual loss and bilateral papilledema is well-described in the literature. We present a case of a 44-year-old, non-obese, female patient presenting with unilateral papilledema and iron-deficiency anemia. This case emphasizes this unusual presentation and the rare association with iron deficiency.
O pseudotumor cerebral é uma patologia relativamente comum, caracterizada pela hipertensão intracraniana na ausência de lesões causando efeito de massa. Frequentemente afeta mulheres jovens e obesas, e sua apresentação, com perda do campo visual e papiledema bilateral, é bem descrita na literatura. Nós apresentamos um caso de uma paciente de 44 anos, não obesa, com papiledema unilateral e anemia ferropriva. Esse caso destaca essa apresentação incomum e a rara associação com a deficiência de ferro.
