Malignant neoplasm of connective and soft tissue, unspecified [C49.9], Reason for Study: ^Reason: aphasia History: metastatic sarcoma There is a 41.7mm (AP) x 39.1mm (RL) x 33.4mm (CC) sized relatively well circumscribed multi-stage hemorrhagic lesion with eccentric enhancing portion on the left frontal lobe with surrounding edema and mass effects. The lesion abuts overlying dura and there is a very short segment of dural enhancement (series 1401, image 130).There is focal susceptibility artifact at the right lateral ventricle frontal horn just above the foramen of Monroe. Diagnostic possibility of the lesion include focal hemorrhagic metastasis, calcification of choroid plexus, or confluence of caudate vein and anterior thalamic vein.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no evidence of acute ischemic lesion.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. 41.7mm (AP) x 39.1mm (RL) x 33.4mm (CC) sized left frontal metastatic lesion with mass effects.2. Susceptibility artifacts on the right lateral ventricle frontal horn as described above.3. No evidence of acute ischemic lesion.
