Aggressive fibromatosis in childhood. Computed tomographic findings in three patients.

Three children with aggressive fibromatosis are presented and the value of computed tomography in defining the extent of the lesions and for follow-up and treatment planning is discussed. Aggressive fibromatosis is a nonmetastasizing fibrous lesion with a propensity for local invasion and recurrence after surgery. The lesions usually have a poorly defined margin on computed tomography and the attenuation coefficient is less than that of muscle with poor enhancement following intravenous administration of contrast material.
