Presentation
Seizure
Patient Data
A 15 x 8 x 10 mm nodule projects into the trigone of the left lateral ventricle. It has a signal characteristics which match those of cortex on all sequences and demonstrates no abnormal contrast enhancement. There is no convincing abnormality of the overlying cortex. Incidental note is made of a small pineal cyst which measures 10 mm in maximal diameter. No abnormal contrast enhancement.
The remainder of the brain appears normal.
Conclusion:
Left sided abnormality is consistent with a focus of grey matter heterotopia.
Case Discussion
Grey matter heterotopia is an important finding in a patient with epilepsy as it can, if solitary, be amenable to resection. It also can prevent inappropriate surgery on the hippocampus.
