RESUMO
Symptomatic venous malformations are uncommon at any age. They are extremely rare in the first decade of life. We describe a 3.5-year-old child with a cerebellar venous malformation presenting with a subacute course mimicking the more common posterior fossa tumors. The child's symptoms were due to a posterior fossa hemorrhage; she subsequently did well. The clinical, CT, angiographic, and pathologic features are described. Venous malformations should be included in the differential diagnosis of young children with evidence of posterior fossa disease.

Iohexol and iopamidol, two new nonionic contrast media, have been extensively studied in comparison with metrizamide for lumbar myelography. Review of the literature with statistical analysis indicates both agents are superior to metrizamide in terms of number of patients with adverse reactions (p less than 0.001). Preliminary data suggest, but do not prove, that use of iohexol may result in fewer side effects than iopamidol.
