A 32-year-old obese female presents to the acute medical unit with a 4-day history of headaches, nausea and vomiting. She was also found to be disorientated. She denied any changes in her vision. On examination, power along her right upper and lower limbs was 3/5. Sensory examination was normal. Ophthalmoscopy revealed bilateral papillary oedema. No nystagmus or ocular palsies were noted. A CT head was performed, and this did not show any abnormalities.

Given the likely diagnosis, which structures may have been affected?
