[Show abstract][Hide abstract] ABSTRACT: A visual field defect is the most important neurologic defect in occipital lobe infarcts. There are only sporadic case reports of altitudinal hemianopia in the published data. We report a patient with bilateral superior altitudinal hemianopia.
A 40-year-old man developed bilateral superior altitudinal hemianopia secondary to bilateral parahippocampal and fusiform gyrus lesions. Vision loss was acute, and onset bilateral and simultaneous. Complete neuro-ophthalmologic examinations were performed. His best corrected visual acuity was 20/20 in each eye. Macula and retina examinations were normal. Visual fields were characterized by bilateral upper hemianopia. Cerebral magnetic resonance imaging (MRI) confirmed the presence of symmetrical lesions confined within both bilateral parahippocampal and fusiform gyri. Blood tests, transesophageal echocardiographic examination, and Doppler ultrasonography of the vertebrobasilar arterial system and carotids were normal.
We conclude that embolic events may induce a bilateral superior altitudinal hemianopia.

CNS tuberculosis has high mortality and morbidity, and it is divided into diffuse (meningitis) and localized (tuberculoma and abscess) forms. The other common site of extrapulmonary tuberculosis is the spine. Modern imaging is a cornerstone in the early diagnosis of CNS tuberculosis and Pott's disease may prevent unnecessary morbidity and mortality. In this case report we describe a case of a 25-year-old man suffering from CNS tuberculoma and Pott's Disease.
