Twelve were female (57%). All were immunocompetent. The median age at symptom onset was 40\u2009years [IQR: 31\u201344]. All patients experienced sensory symptoms, 19 (90%) reported neuropathic pain, nine (43%) developed motor weakness, and seven (33%) had cranial nerve involvement. The most frequently involved nerves were the median (14 patients, 67%), fibular (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200913; 62%), and ulnar (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200910; 48%) nerves.

Nerve biopsy showed necrotizing small\u2010vessel vasculitis in one patient (17%), perivascular lymphocytic and macrophagic infiltrates in five (83%), and B19V DNA was detected by PCR in all four tested nerves.
