Other malformations of cerebral vessels [Q28.3] / Other nontraumatic intracerebral hemorrhage [I61.8], Reason for Study: ^Reason: CCM brain with recent hemorrhage, 6 month follow up to eval for changes History: hemorrhage CCM Previously seen 3rd ventricular hemorrhagic lesion has been continuously evolving in its shape and MR characteristics. In terms of its size, the maximum diameter appears to be stable around 9mm but the configuration has been slightly elongated toward craniocaudal direction since prior scan.In addition, the superior aspect of the lesion is now showing typical multi compartmentalized appearance with fluid fluid level within those compartments (arrows). There is no evidence of Gad enhancement of the lesion. There is no other susceptibility lesion seen on this scan.Constellation of above findings suggest the diagnosis of cavernous malformation. The ventricles, sulci and cisterns are unremarkable. 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 on bilateral maxillary sinuses and ethmoid sinuses.
1. Continuously evolving 3rd ventricle hemorrhagic mass lesion with more conspicuous multi compartmentalization with intra compartmental fluid-fluid level indicating the diagnosis of cavernous malformation.2. No significant interval change of the size of the lesion since prior scan. No new susceptibility lesion is seen.
