Axial section of brain.Figure 1 was found to have a focal irregular area of nodular non-enhancing soft tissue thickening in relation to the retina just adjacent to the optic nerve insertion, which appears hyperdense in the unenhanced study. This is suggestive of a retinal lesion (inflammatory, non-benign or haemorrhage) or artefactual. No calcifications are present. Intraocular and extracoronal spaces are intact bilaterally.Computed tomography (CT) image of patient’s brain.
