intracranial abscess [324.0], Reason for Study: ^Reason: hx intracranial abscess. Evaluate change/ resolution History: surveillance Redemonstration of the right thalamic lesion with susceptibility artifacts with focal tissue loss. The lesion shows ill defined punctate subtle enhancement on gadolinium infusion, there is possibility of associated enlarged parenchymal venous structure on the right lateral ventricle. Above described findings constitute possible diagnosis of cavernous malformation associated with developmental venous anomaly.These findings do not show any interval change since prior study imaging scan. Right frontal burr hole, no significant interval change.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.
1. Right thalamic lesion with susceptibility artifacts suggest cavernous malformation with associated DVA, no interval change since prior scan.2. No acute ischemic lesion.3. Otherwise no remarkable finding since prior scan.
