“…The mesodiencephalon has been implicated both in hemi-seesaw and convergenceretraction nystagmus 6,7,9 . Simultaneous occurrence however is rare and has only been reported with extensive subcortical lesions 9,19 , limiting precise neuroanatomical conclusions. Here, MRI revealed a solitary focal midbrain lesion adjacent to the posterior commissure, hinting at a circumscribed neuroanatomical origin for both oscillations.…”

“…From 2010 and 2017, several authors [21][22][23][24][25][26] also reported a case series of ischemic stroke on the thalamus and different clinical manifestations. Other clinical presentations of TMS include see-saw nystagmus that shows intorsion and elevation of one eye, with synchronous extorsion and depression on the contralateral one, convergence-retraction nystagmus and contraversive ocular tilt reaction probable due to ischemic involvement of the interstitial nucleus of Cajal 27 , anisocoria. Another author found vertical ocular motor disturbances in the vertical plane and eye movement synkinesis, hypersomnia, and coma as a clinical manifestation of TMS 28 .…”

Case Report: Thalamomesencephalic stroke due to vasculitis in a patient with HIV

We present a 41-year-old HIV-positive female patient complaining of complete right palpebral ptosis, diplopia, and inability to balance herself. On examination, the right eye was able to move laterally and downwards. The motor exam showed left hemiparesis (4/5) on upper and lower limbs, bilateral Babinski sign with left hemiataxia without the sensory disorder. A computed tomography (CT) angiogram confirmed a diffuse vasculitis with parenchymal changes in the right thalamus and midbrain. CT scan and magnetic resonance imaging angiography demonstrated an ischemic infarct on the right paramedian branch of the posterior cerebral artery territory. This patient did not present clinical manifestations of the thalamic lesion. To our knowledge, this is the first reported case of a young patient presenting a unilateral thalamomesencephalic ischemic stroke secondary to HIV vasculitis with bilateral Babinski signs and without thalamic signs in the medical literature.
