Compressive optic neuropathy with acute or chronic vision loss has been associated with various skull base tumors, aneurysms, Graves disease, trauma, and, less commonly, fibrous dysplasia and osteopetrosis. The authors present a case of acute visual deterioration in a 25-year-old woman who had massive calvarial hypertrophy with optic canal stenosis secondary to renal osteodystrophy (uremic leon...

Warburg syndrome is a recently defined autosomal recessive oculocerebral syndrome. It was previously given the acronym HARD +/- E, indicating what were regarded as the pathognomonic features, namely hydrocephalus, agyria, and retinal dysplasia with or without encephalocele. We report the case of a male infant with the typical cerebral features of hydrocephalus, agyria, and pseudoencephalocele, ...

BACKGROUND Fibrous dysplasia (FD) is a benign bone tumor which most commonly involves the craniofacial skeleton. The most devastating consequence of craniofacial FD (CFD) is loss of vision due to optic nerve compression (ONC). Radiological evidence of ONC is common, however the management of this condition is not well established. Our objective was to compare the long-term outcome of patients w...

BACKGROUND AND PURPOSE Midbrain-hindbrain involvement in septo-optic dysplasia has not been well described, despite reported mutations of genes regulating brain stem patterning. We aimed to describe midbrain-hindbrain involvement in patients with septo-optic dysplasia and to identify possible clinical-neuroimaging correlations. MATERIALS AND METHODS Using MR imaging, we categorized 38 patient...
