“…Some of the bilateral thalamic infarcts, as established on imaging might have been isolated right thalamic afflictions initially 6. The presence of smaller collateral venous channels draining the right thalamus is found more often on the right side in the setting of bilateral internal CVT 7 8. This may mirror the well-known asymmetry where the superior sagittal sinus drains preferentially into the right transverse sinus 9.…”

Isolated deep cerebral venous thrombosis (CVT), especially involving only the right thalamus, is one of the rarest forms of intracranial venous thrombosis in a child. The anatomy and flow patterns of the deep cerebral venous system are complex and usually, the thrombosis of the internal cerebral veins (ICV) results in thalamic infarction bilaterally. The focal infections, thalamic tumours and vascular malformations may have overlapping clinicoradiological patterns. The treating team should be able to recognise the atypical phenotypes of the deep CVT at the earliest, which can facilitate apt treatment and obviate the need for unnecessary investigations and interventions. We present a rare case of an isolated right thalamic acute venous infarct secondary to bilateral ICV thrombosis in a toddler who was successfully managed by timely diagnosis and with only conservative therapy.

“…The vein of Galen and straight sinus thrombosis typically show bilateral thalamic lesions [ 3 ]. However, very rarely, the vein of Galen and straight sinus thrombosis shows a unilateral deep cerebral lesion, especially on the left side [ 6 , 7 ]. Although the asymmetry of the venous outflow tract may be speculated as one possible mechanism [ 7 ], imaging has not confirmed its mechanism.…”

“…However, very rarely, the vein of Galen and straight sinus thrombosis present unilateral deep cerebral lesions [ 4 , 5 ]. Although unilateral deep cerebral lesions by straight sinus thrombosis have been reported to be more common on the left [ 6 , 7 ], their mechanism has not been fully investigated. We report a case of the vein of Galen and straight sinus thrombosis with unilateral deep cerebral lesions which would be derived from the anatomic asymmetrical deep cerebral venous outflow.…”

A 60-year-old man was admitted to our hospital due to progressive aphasia and right hemiparesis. Brain magnetic resonance imaging showed the left thalamus and basal ganglia lesion. Digital subtraction angiography showed the vein of Galen and straight sinus occlusion, suggesting cerebral venous thrombosis. Since his left transverse sinus was hypoplastic, his left deep cerebral lesion was due to the left deep cerebral vein congestion by the asymmetrical venous outflow. After anticoagulant therapy, his symptom and unilateral lesion improved. Clinicians should consider the vein of Galen and straight sinus thrombosis even in unilateral deep cerebral lesions.

Background: Cerebral venous thrombosis (CVT) is a rare form of stroke in infants and young children, with multifactorial causation and a poor prognosis. Bilateral haemorrhagic thalamic infarction secondary to deep CVT is an extremely rare presentation. Case report: We report the case of a 12-month-old infant with bilateral haemorrhagic thalamic infarction secondary to deep CVT, presenting with fever and seizures. The infant was initially diagnosed with acute meningoencephalitis of viral aetiology and treated accordingly. However, the patient had a sudden clinical deterioration. Neuroimaging revealed deep CVT with bilateral haemorrhagic thalamic infarction. Anticoagulant therapy in conjunction with physiotherapy was initiated and the infant gradually improved and was discharged. Conclusion: CVT is a rare form of stroke in infants and young children, with multifactorial causation and poor prognosis. Our case highlights the importance of careful evaluation of cerebral venous drainage on routine neuroimaging in infants with fever and seizures, especially in those who do not respond to standard treatment for meningoencephalitis. Synopsis: Here we report a unique and challenging case of deep cerebral venous thrombosis with haemorrhagic infarction of bilateral thalami mimicking viral encephalitis in an infant with acute febrile encephalopathy.
