RESUMO

Despite the lipomas are the tumors that more commonly occur in the corpus callosum (CC), its incidence in the population is not common. We report on a 5-year old boy, with history of retardation in the psychomotor development and disturbs in the gait, secondary to generalized hypotony. Magnetic resonance imaging showed a curvilinear lipoma of the CC related to its hypertrophy. In the literature patients with CC lipoma usually have agenesis or hypotrophy of the CC, but in the reported case we have seen, by the first time, a hypertrophy of the CC. We made embryologic, genetic, clinical, radiographic and therapeutic considerations about the patients that have CC lipoma comparing to findings in the case we report.
