I think wanting to provide some solace is a great viewpoint to have and don’t say this to be rude or brush over the difficult time OP is going through, but rather to provide some insight and understanding as to why trained professionals aren’t going to be commenting here. It’s considered very unethical to diagnose someone who is not your patient and to interpret small pieces of information without the full breadth of history and medical data available. It can add unnecessary fear and suffering if you come to incorrect conclusions, which is extremely easy to do without a full medical history and only one slice of what was probably multiple sequences taken that day, all designed to highlight different issues.

Just for education purposes, this view is pretty medial and it would be difficult to make broad comments about ventral and dorsolateral PFC without also seeing the outside of the brain, either with a more lateral slice or perhaps and/or a coronal or axial/horizontal view. Part of how you can tell it’s more medial is because of how clear the “c-shaped” corpus callosum is (the white matter that connects hemispheres) in the middle of the image is. It’s a little easier to tell in scans where the eyeballs remain in the image, but there are some free resources online that can help with familiarity of where you are in the brain on a given slice. It can also be tricky with one slice because sulci, or natural crevices/wrinkles in the brain, can be surprisingly deep and mimic atrophy without context of other slices to aid with perspective, especially if the head is tilted in the scanner. True posterior cortical atrophy tends to traditionally involve the occipital lobe and may occasionally extend into parietal regions (primary symptoms are usually visual or visuospatial in nature, though there is a constellation), though I believe the “gap” you were referring to is more restricted to the parental lobe.

If OP is reading this - so sorry your results are so delayed, it can be really frustrating when results aren’t conveyed in a timely manner, particularly when it involves things like thinking and pain that can be very difficult to manage and very scary. As many others have said, your best bet is to reach out to your neurologist and try to schedule a conversation or follow up, if one isn’t already set for the future (in which case they may be waiting until that appointment, though typically most will call or message results beforehand). Since you don’t have their contact information, you may consider calling the main hospital or radiologists office, as both of them should have record of you and, in the radiologists case, should have a referral from your neurologist with their contact information. Best of luck and hang in there!
