Brain heterotopia.
We present a case with intractable partial complex seizures in a 14-year-old girl who was found to have brain heterotopia on MRI and PET-CT. The patient presented with intractable partial complex seizures and a normal electroencephalogram. Her brain magnetic resonance imaging showed heterotopic gray matter lining the ventricular margin of the right occipital horn. Subsequent PET-CT demonstrated moderate tracer localization in the heterotopic gray matter surrounding the ventricular margin of the right occipital horn. Heterotopia may demonstrate normal or increased FDG uptake on PET, therefore its appearance may be deceiving when other pathologies are being considered.
