Hypotonia and progressive hearing loss. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is faint linear enhancement in the left middle frontal gyrus, which likely represents a developmental venous anomaly. Otherwise, there is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The inner ear structures are unremarkable. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
No evidence of infarct or other lesions to suggest an underlying mitochondrial disorder.
