 An enhancing mass within the right occipital lobe has increased over the interval, now measuring 30 x 32 mm transaxial dimension (previously 25 x 21-mm). Additionally, it now appears more centrally necrotic, with enhancement abutting the lateral aspect of the resection cavity, with new extensive edema extending anteriorly.Redemonstrated are post-surgical changes related to a right parieto-occipital craniotomy for prior tumor resection with new nodular enhancement along its medial aspect with worsening edema also along its lateral aspect. Normal flow-voids are demonstrated in the major intracranial vascular structures.
