Intracerebral hemorrhage [431], Reason for Study: ^Reason: aneurysm History: hx aneurysm There is about 8 mm sized lesion on the left posterior superior aspect of gyrus rectus. The lesion shows low signal intensity rim with the speckled internal low signal intensity on gradient echo indicating hemosiderin deposition. There is no surrounding edema. Small focal high signal intensity in side of the lesion may indicate subacute hemorrhage. Above described findings are indicating cavernous malformation on the left posterior superior gyrus rectus.There are no other lesion is seen on the scan. However, dedicated gradient echo MR imaging could be necessary to clarify additional parenchymal lesions if clinically indicated.There is no evidence of acute ischemic lesion on the scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.3D 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. Focal hemorrhagic lesion on the left posterior superior aspect of gyrus rectus, most likely represent cavernous malformation.2. Otherwise unremarkable brain MRI and MRA.
