Male, 18 years old, with history of hemoglobin SS undergoing pre-stem cell transplant evaluation. No significant parenchymal signal abnormality is seen. There is no evidence of edema or mass effect. Diffusion-weighted images are within normal limits. No intracranial hemorrhage or abnormal extra-axial fluid is detected. The ventricular system is normal in size and morphology. A normal variant subcentimeter hippocampal sulcus remnant cyst is seen along the left medial temporal lobe. A subcentimeter focus of T1/T2 hyperintense signal is seen along the inner table of the left parietal bone, likely benign and of doubtful significance.On angiographic imaging, no significant intracranial vascular stenosis or occlusion is seen. The vessels of the anterior and posterior circulation demonstrate normal flow related signal. No aneurysm or vascular malformation is detected.
1.No significant brain parenchymal abnormalities are seen.2.Unremarkable evaluation of the intracranial vasculature.
