Tension-type headache, unspecified, not intractable [G44.209], Reason for Study: ^Reason: Assess response to radiation and chemotherapy. Pt experiencing muscle contraction sensation along left skull History: Previously seen left frontal extra dural enhancing lesion appears to be slightly thinner than prior (4.2mm, 6.3mm in maximum thickness previously).Overlying sclerotic left frontal skull metastatic lesion does not show any interval change.There is no evidence of new abnormal enhancement on the scan.There is no evidence of acute ischemic or hemorrhagic 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. Interval decrease in thickness of left frontal lobe extra dural enhancing lesion since prior scan.2. Stable left frontal skull sclerotic metastatic lesion since prior scan.
