BACKGROUND: Cerebellar hemangioblastomas are unusual benign neoplasms
that may go undetected for years. When associated with pregnancy, howe
ver, these tumors may undergo rapid expansion and promote progression
of symptomatology. CASE: A 28-year-old woman with ataxia and left-side
d weakness was diagnosed with cerebellar hemangioblastoma in the secon
d trimester of pregnancy following repeated hospital admissions for na
usea and vomiting. Surgical removal was uneventful, and she delivered
vaginally at term. CONCLUSION: Cerebellar hemangioblastomas, although
rare, should be considered in the differential diagnosis of persistent
nausea and vomiting when accompanied by an abnormal neurologic examin
ation.
