A 70-year-old woman with systemic lupus erythematosus developed a painful pupil-involving right third nerve palsy, ipsilateral fourth nerve palsy, and periorbital paraesthesia. Magnetic resonance imaging demonstrated enhancement and thickening of the right third nerve, and she was diagnosed with presumed Tolosa-Hunt syndrome. Repeated imaging seven months later showed resolution of the enhancing thickened oculomotor nerve, but the patient developed signs of oculomotor synkinesis.

Article Synopsis
- A 45-year-old woman experienced intermittent left eye pain and double vision over 12 years, always linked to a sixth cranial nerve palsy.
- Postcontrast brain MRIs showed enhancement of the left sixth cranial nerve during an episode, which normalised five months later when symptoms improved.
- This case supports the diagnosis of "ophthalmoplegic migraine" and is notable for being the first report of cisternal enhancement specifically affecting the sixth cranial nerve.
Article Synopsis
- Posterior cortical atrophy starts with visual symptoms before progressing to more complex issues like visual agnosia and spatial disorientation.
- Over time, patients may exhibit symptoms of Balint's syndrome and Gerstmann's syndrome, which affect reading, writing, and basic cognitive functions.
- The condition can be linked to various underlying neuropathological disorders and may also include hallucinations and signs associated with Parkinson's disease or Lewy body dementia.
Article Synopsis
- Four patients experienced a reversible type of vision loss called homonymous hemianopia due to non-ketotic hyperglycemia.
- Two of these patients were first diagnosed with type 2 diabetes mellitus as a result of this vision loss.
- MRI scans showed abnormal results in all four patients, but follow-up scans indicated that these abnormalities completely resolved in three of them.
