Although transverse myelitis classically presents with bilateral and symmetric symptoms, it may be “partial” - symptoms would be asymmetric, or specific only to particular anatomic tracts.
In patients with risk factors (e.g. recent infection, history of autoimmune disease or cancer) and subacute ascending weakness/sensory symptoms, perform a thorough neurological exam, and obtain a gadolinium-enhanced MRI of the entire spine and/or lumbar puncture if you suspect transverse myelitis.
