 MRI Brain:There is no evidence of acute infarct, hemorrhage, mass, or mass effect. There are patchy foci of susceptibility involving the bilateral basal ganglia which may represent mineralization/calcification. Small focus of mineralization involving the left midbrain also noted. There is also focus of susceptibility involving the right frontal centrum semiovale with faint T2 hyperintensity, which is nonspecific and may be related to mineralization or a capillary telangiectasia. There is no abnormal parenchymal or meningeal enhancement. No extra-axial collections. Ventricles are normal in size. There is a 3 mm focus of nonenhancement within the pituitary gland which may represent a tiny pars intermedia or Rathke's cleft cyst. Orbits and sella are otherwise grossly unremarkable. There is minimal scattered paranasal sinus opacification including small maxillary sinus mucus retention cysts. Bone marrow signal and extracranial soft tissues are grossly unremarkable.MRA Brain: The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. The vertebral arteries, basilar artery, and posterior cerebral arteries also are patent with no significant stenosis. Left posterior cerebral artery is fetal in origin which is a normal variant. Left vertebral artery is dominant. No evidence of aneurysms or vascular malformations.
1. There is no intracranial mass, mass effect, parenchymal edema, or abnormal enhancement.2. Scattered foci of susceptibility of what likely represents mineralization in the basal ganglia. The nodular pattern and extent however appears somewhat unusual for physiologic mineralization in this age group. CT may be helpful for further assessment of extent of mineralization or calcification. This finding is nonspecific but can be seen with metabolic conditions such as disorders of calcium metabolism, for example. The right frontal lobe focus of susceptibility may represent capillary telangiectasia which is a normal variant.3.. Unremarkable brain MRA without evidence of aneurysm.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
