Background The unilateral fetal variant of the posterior cerebral artery (FPCA) is characterized by the congenital absence of the P1 arterial segment. The artery of Percheron (AOP) is an uncommon vascular variant, in which a single dominant thalamoperforating arterial trunk arises from one P1 segment, bifurcates, and provides bilateral supply to the paramedian thalami and rostral midbrain. Case Presentation This is a retrospective case study of a 37-year-old man with multiple lifestyle risk factors (chronic marijuana and tobacco abuse), who suffered a thalamomesencephalic stroke, rapidly worsening to comatose state. After restoration of consciousness, he clinically manifested with left paramedian midbrain syndrome. Imaging demonstrated an asymmetric paramedian thalamic infarction with mesencephalon extension, patency of the basilar, vertebral arteries, and left PCA and right-sided FPCA, respectively. Left-sided thalamoperforating arterioles were not differentiated; AOP was inferred. Neither evident clinical source of embolus nor prothrombotic states were found. Mobile cardiac telemetry and transesophageal echocardiography were not available. The diagnosis was established too late for thrombolytic treatment. Anticoagulation was indicated during the acute and subacute stages, followed by low dose of antiplatelet. Discussion This uncommon cerebrovascular configuration (FPCA+AOP) might be the fourth case described in the literature. Sustained rehabilitation and abstinence from tobacco and cannabis led to favorable outcomes.

“…An investigation done on human cadaveric brains have been demonstrated four major thalamic arterial territories, with notable blood variations. These areas receive blood supply by the polar, paramedian/thalamoperforating arteries, thalamogeniculate, and posterior choroidal arteries [9][10][11][12][13][14][15][16][17] . The perforating arteries supply the medial the walls of the third ventricle, hypothalamus, and subthalamic-mesencephalic junctions.…”

“…The perforating arteries supply the medial the walls of the third ventricle, hypothalamus, and subthalamic-mesencephalic junctions. These areas include the oculomotor nucleus, red nucleus, subthalamic nucleus, substantia nigra, pretectum, trochlear nucleus, reticular formation of the midbrain, posterior part of the internal capsule, the rhomboid fossa, and the rear part of the thalamus [9][10][11][12][13][14][15][16][17][18][19][20] . Because the artery of Percheron occlusion can affect the thalamus and midbrain at the same time, here we have to mention that artery of Percheron is an uncommon vascular variant of the paramedian branches of the posterior cerebral artery, arising from one P1 segment, bifurcates, and bilateral supply to the bilateral paramedian thalami and the rostral midbrain 10,11 but not unilaterally.…”

Case Report: Thalamomesencephalic stroke 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. 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.

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.
