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.

There were no periventricular plaques, calcifications, infarcts, or pathological enhancements (Figures 1-3).

Figure 5 depicts the left eye with tractional bands and shows a 'double-walled sign' suggestive of echinococcal cystic cavity, causing traction on the retina.  
Optical coherence tomography (OCT) scan pre- and post-injection of right eye with orbital floor steroids. Significant decrease in inflammation was noted after injection of the right eye 2 months after steroid injection in 2020.

Optical coherence tomography (OCT) revealed a central pre-injection macula thickness of 445 microm on the right and 446 microm on the left with intraretinal and subretinal fluid (Figure 6).
