Eosinophilic granulomatous polyangiitis (EGPA) like other antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis has multisystemic involvement. It commonly manifests with prodromal pulmonary involvement as asthma, chronic sinusitis followed by systemic vasculitic complications associated with blood and tissue eosinophilia. Central nervous system manifestations at presentation are uncommon compared with peripheral nervous system involvement. Vasculitic neuropathy in EGPA commonly presents as mononeuritis multiplex but rarely as polyradiculopathy. Late onset EGPA often presents with systemic involvement, and early diagnosis is a key to prevent further complications. The neuropathy in late onset EGPA is often refractory to immunosuppression and corticosteroids treatment. We report a case of EGPA with late onset asthma presenting with acute infarct and demyelinating polyradiculoneuropathy that progressed with bulbar paralysis and profound dysautonomia. This illustrates simultaneous involvement of central and peripheral nervous system with EGPA. Autonomic dysfunction can occur in patients of EGPA with multisystem involvement, which may predict severe complications.

Review
For cauda equina syndrome (CES), current clinical assessment in the emergency department usually involves perianal sensation (PAS) and anal tone (AT). Neither reliably predict magnetic resonance imaging (MRI) demonstrating a large central disc prolapse (MRI+). Other clinical examination findings increase the probability of MRI+. Other tests of sacral nerve root function include anal squeeze (AS) and the bulbocavernosus reflex (BCR). If BCR, PAS and AT, and AS are combined and they are all normal, CES can be excluded in almost all cases. Portable bladder ultrasonography is now commonly used to assess bladder function, particularly in measuring the post-void residual urinary volume (PVR). PVR is deemed normal at <50ml. If the PVR is <200ml and there are no objective signs, MRI+ is rare. If the PVR is >200ml, MRI+ is found in 43% of cases. The combined assessment of PAS, AT and AS (and BCR in selected cases) and PVR increases the specificity and sensitivity of a clinical diagnosis of CES (i.e. maximising MRI+ and minimising MRI-). Recommendations for when to perform MRI are made.
