Abstract Objective Heterotopia is a rare condition typically identified in the context of seizures. This case study presents a cognitive profile in a child with a history of heterotopia and hearing problems but without any known seizure history. Method An 8-year-old referred for evaluation by her neurologist due to concerns about persistent academic and social difficulties. Medical history was remarkable for small size, hearing problems, multiple pressure equalization tube placements, food allergies, and a left lateral ventricle gray matter heterotopia found on brain MRI. EEG was normal. Genetic testing found no dysmorphia. Developmental history was remarkable for delayed speech and early intervention, as well as social delays. She began receiving special education for learning disability and speech/language impairment in first grade. Results WISC-V IQ was Low Average and significantly lower than GAI. WMI was Below Average and PSI was Low. Language performance was variable. Visual scanning was Below Average. Verbal memory ranged from Below Average to Impaired, with worse performance on WRAML-2 Story Memory subtests. Attention and hyperactivity deficits were found on a continuous performance task. Executive function was Average to Above Average on phonemic fluency, category switching and Stroop tasks. BASC-3 parent ratings indicated greatest concerns in areas of atypicality, withdrawal, and adaptive skills. ABAS-3 indicated Low conceptual skills and Average to Low Average skills on other composites. Conclusions Aside from language deficits likely related to hearing problems, these findings indicated deficits in visual scanning, attention/hyperactivity, visually-based processing speed, and memory in the context of heterotopia without seizures. Social delays may be multifactorial.
