| The majority of participants had tetraplegia, whereas 21 percent had diplegia, 16 percent had hemiplegia, and 2 percent had monoplegia. |
| Our case was unusual in that the patient only had monoplegia in her right upper limb, with no preceding symptoms. |
| We report the unusual case of a 77-year-old female who presented to our emergency department with sudden onset isolated hypoaesthesia and right upper limb monoplegia. |
| A generalized asymmetric tetraplegia or quadriplegia was the most common weakness pattern, followed by monoplegia. |
| There can also be hemiplegia, affecting one half of the body, or monoplegia, affecting one limb. |
| Such conditions as transient hemiplegia, monoplegia or aphasia may occur. |
