Letter to the Editor


Pontine hemorrhage (PH), comprises less than 10% of all intracerebral hemorrhages, and causes vestibular dysfunction (dizziness or vertigo), abnormality of eye movements, ataxia, and dysarthria [1, 2, 3]. Among neurological deficits, vestibular dysfunction is mainly associated with lesions on the tegmentum of pons, and 44% of patients with tegmentum of pons lesion report dizziness or vertigo, because this region includes the vestibular nuclei (VN) [4].

The ipsilateral vestibulothalamic tract (VTT), which originates from the VN and runs to the tegmentum of pons, is involved in the conscious perception of movement and spatial orientation. Hence, injury of the VTT can be accompanied by dizziness or vertigo [5, 6, 7]. However, little is known about this area in the live human brain because of anatomical features (deep location and ambiguous identification) in conventional brain magnetic resonance imaging [6, 8]. In brain imaging tools, recent diffusion tensor tractography...
