Osteopetrosis, pre-transplant workup recommended to detect narrowing of nerve channels, neuropathic changes, and hydrocephalus. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The degree of myelination appears to be appropriate for age. The ventricles and basal cisterns are normal in size and configuration. However, there is prominence of the bilateral anterior frontal and temporal convexity subarachnoid spaces. There is a mega cisterna magna. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, paranasal sinuses, and scalp soft tissues are grossly unremarkable. Osseous findings related to osteopetrosis are better depicted on CT.
1. No evidence of acute intracranial hemorrhage, mass, cerebral infarction, or ventriculomegaly.2. Prominence of the bilateral anterior frontal and temporal convexity subarachnoid spaces, which represents external hydrocephalus.3. Refer to the concurrent CT regarding findings related to osteopetrosis.
