Hb-SS disease with crisis, unspecified [D57.00], Reason for Study: ^Reason: SCD History: eval for Moya Moya/stenosis Brain MRINo evidence of acute ischemic or hemorrhagic lesion. The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. Mucosal thickenings are seen on bilateral maxillary sinuses. The left sphenoid bony lesion is again seen, unchanged since prior scan.Considering the patient clinical circumstances of moyamoya disease with acute crisis, post gadolinium enhanced the scan could be indicated to evaluate perivascular inflammatory changes. Therefore, if clinically indicated brain MRI with and without contrast enhancement can be considered.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Unchanged left sphenoid benign looking bony lesion.3. No evidence of intracranial arterial stenosis or occlusion. Rec: With clinical circumstances of sickle cell disease with crisis, Gad enhanced MRI can be considered to evaluate vascular enhancement.
