Spontaneous nystagmus (of central type in 2 cases) was recorded in all patients. The Head Impulse Test was clearly negative in 9 cases. The duration of vertigo lasted more than 72 hours in 7 patients. In 4 patients, delayed neurological signs followed acute vertigo 2 to 3\u00a0days after the onset. Magnetic resonance imaging showed 8 cases of infarction in the posterior\u2010inferior cerebellar artery territory; in 1 patient, an involvement of the anterior\u2010inferior cerebellar artery territory was recorded; 2 patients showed a hemispheric ischemic cerebellar involvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pseudo\u2010APV is not an uncommon diagnosis in otoneurological practice. The presence of moderate\u2010severe imbalance and the persistence of vertigo for more than 72 h from the onset, together with the results of bedside examination tests (spontaneous nystagmus and Head Impulse Test), are useful indicators for recognizing a cerebellar ischemic origin in cases of acute vertigo.<\/jats:p>\n
