title: Vincristine-induced megacolon.
abstract: Three cases of vincristine-induced megacolon are described with radiographic correlation. Vincristine is a widely used chemotherapeutic agent with neuropathic side effects causing colonic dilatation and constipation. The radiologist should be aware of this entity to prevent unnecessary procedures and, possibly, surgery.
