Background
Parsonage Turner syndrome (PTS), also known as neuralgic amyotrophy or
idiopathic brachial plexopathy, is a rare peripheral multifocal
inflammatory neuropathy that usually affects the upper limbs(1).
However, it is widely misdiagnosed because of its heterogeneous clinical
appearance(2). The classic presentation is a patient with subacute onset
of asymmetric shoulder pain, followed several days later by weakness and
amyotrophy(3). Although its exact cause is still unknown, multiple
factors have been identified such as immunological (infection,
vaccination, surgery, pregnancy, physical or mental stress), mechanical
(trauma, sports or heavy labor) and genetic factors(4). In the last
years PTS has been associated with severe covid-19 infection as well as
its vaccination(5). Therefore, we report a rare case of a sub acute
onset of PTS as a result of Covid-19 vaccine.
