A rare neurological condition, akinetopsia (visual motion blindness), is presented in a patient with brain metastases from breast cancer. This case highlights a novel association between akinetopsia and metastatic brain disease.
Area of Science:
- Neurology
- Neuro-oncology
- Ophthalmology
Background:
- Akinetopsia, or visual motion blindness, is a rare neurological disorder characterized by the inability to perceive motion.
- It typically results from brain damage caused by ischemia, epilepsy, or medication.
Observation:
- This report details a unique case of akinetopsia in a patient experiencing a late breast cancer relapse with multiple brain metastases.
- The patient also presented with impaired perception of object movement, visual hallucinations, night terrors, and anterograde memory difficulties.
Findings:
- Neuroimaging (MRI) revealed significant brain damage, particularly in the middle temporal area of the visual cortex.
- This is the first documented instance of akinetopsia associated with brain metastases.
Implications:
- This case expands the known etiologies of akinetopsia, suggesting brain metastases as a potential cause.
- It underscores the importance of considering complex neurological syndromes in cancer patients with brain metastases.
