Diagnosis: Sickle-cell disease without crisisDiagnosis Edits: Clinical question: sickle cell ds Signs and Symptoms: eval for moya moya/stenosis MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.There is no evidence for intracranial cerebrovascular occlusion. The anterior communicating artery is identified. The posterior communicating arteries are asymmetric. The right posterior communicating artery is almost is large in diameter as the right P1 segment the left posterior communicating artery is small. The right posterior communicating artery is larger than the left posterior communicating artery. The vertebral arteries are similar in size.Low marrow signal is a nonspecific finding but expected in a patient with sickle cell disease.
1.No evidence for cerebrovascular occlusive disease. There is no evidence for moyamoya.2.No evidence for cerebral infarction.
