History of concussions with migraines without aura. There is a small nodular thickening at the right ventricular atrium which follows the signal of cortex with an associated radial migration line extending peripherally. There is no evidence of intracranial hemorrhage, mass effect, or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
Small cortical heterotopia suspected at the right ventricular atrium. The relevance of this finding to patient's complaint is uncertain. No other findings to account for her symptoms.
