orbital lymphoma follow up Brain MRILeft temporal small craniotomy site and skull base area shows minimal smooth dural enhancement which is likely represent postoperative in nature. Comparing to prior study, there is no significant interval change in terms of enhancement pattern and characteristics.Scalp, left temporalis muscle as well as left masticator space also show no evidence of abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. Bilateral mastoid air cells show fluid collections. There is fluid collection on the left frontal sinus indicating possible localized sinusitis. No change of partial empty sellar.Orbit MRI:There is no evidence of abnormal thickening or enhancement on extra ocular muscles.In particular, the right superior rectus muscle appears to be normal in size without showing evidence of abnormal enhancement.Other orbital contents appear to be unremarkable.
1. Stable minimal smooth enhancement of left temporal lobe and skull base dura indicating postoperative change since prior exam.2. No evidence of abnormal enhancement on scalp, temporalis muscle, left masticator space and right superior rectus muscle.3. Bilateral mastoid fluid collections and left frontal sinusitis.
