Effect of pregnancy on hemangioblastoma development and progression in von Hippel-Lindau disease
2012
Object Prior cases suggest that pregnancy increases the development and progression of CNS hemangioblastomas and/or peritumoral cysts. To determine the effect of pregnancy on CNS hemangioblastomas and peritumoral cysts, the authors prospectively evaluated serial clinical and imaging findings in patients with von Hippel-Lindau (VHL) disease who became pregnant and compared findings during pregnancy to findings in the same patients when they were not pregnant as well as to findings from a cohort of VHL patients who did not become pregnant. Methods Female VHL disease patients enrolled in a prospective natural history study who were of reproductive age (16–35 years at study entrance) were included. Analysis of serial clinical and imaging findings was performed. Results Thirty-six consecutive female VHL disease patients harboring 177 hemangioblastomas were included (mean follow-up [± SD] 7.5 ± 2.3 years). Nine patients (25%) became pregnant (pregnancy cohort). The mean rates of development of new hemangioblast...
