This report presents the results of 10 years of observation and testing of a female child with a congenital agenesis of the corpus callosum. The agenesis was diagnosed from CT scans completed to rule out neurological causes for developmental delays. Results of this longitudinal observation and testing revealed that language and speech evolved over time. Despite extensive speech and language treatment, a persistent language impairment continued to exist. Each year there was a widening gap between the child's language skills and those expected for her age. A prominent feature of the language impairment was a pragmatic deficit. A moderate oral apraxia was also present throughout the 10-year period during which this child was observed.
