16-month-old female with first time seizures: eyes rolling back, bilateral extremity shaking. Evaluate for structural abnormalities. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears within normal limits. No findings to suggest seizure focus are appreciated. Specifically, there is no evidence of gray matter heterotopia or cortical dysplasia. The bilateral hippocampi are symmetric in size, signal characteristics, and with preserved internal architecture. There is no abnormal intracranial enhancement. A 10 mm cystic focus is evident within the right occipital lobe, in line with the expected location of the occipital horn of the lateral ventricle. This collection follows CSF signal on all sequences with no surrounding parenchymal abnormality. The ventricles and basal cisterns are otherwise normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. Please note that artifact of uncertain etiology obscures the left aspect of the posterior fossa on certain sequences.
No specific findings are seen to account for the patient's seizures. A cystic focus within the right occipital lobe likely reflects a normal variant partial sequestration of the occipital horn, or perhaps a neuroglial cyst.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
