“…Her left visual field was recovered, but exhibited right homonymous hemianopsia when she was discharged. Ko et al ( 2001 ) reported a case of a 54-year-old female whose main manifestations were sudden severe headaches and progressive bilateral loss of vision within 1 day. She was conscious when admitted, and there was no abnormality on a neurological examination.…”

Cerebral venous thrombosis (CVT), also called cerebral venous sinus thrombosis (CVST), is a cerebrovascular disease with diverse clinical manifestations that often affects young adults, women of childbearing age, and children. It's most common clinical manifestations are headache, seizures, altered consciousness, and neurological focal signs on physical examination. CVT can manifest as a single symptom, or it can present as a syndrome consisting of multiple symptoms. This non-specific clinical picture makes diagnosing CVT difficult. Although the mortality rate of CVT has been significantly reduced by improvements in treatment and diagnostic techniques, the mortality rate of severe CVT remains as high as 34.2%. Survivors of this type of CVT have varying degrees of residual symptoms and are not able to return to their previous work. Hence, we performed a comprehensive literature search in the PubMed, EMBASE, and Medline databases to review the diagnosis and treatment of CVT.

“…Cortical blindness associated with CVST is very unusual and literature review has further revealed only a handful of case reports. 5–7 Here, we describe a rare case of reversible cortical blindness due to bilateral occipital infarction resulting from CVST.…”

Cerebral venous sinus thrombosis (CVST) is not an uncommon cause of stroke but very often unrecognized at initial presentation due to lack of clinical suspicion and thus frequently left untreated. CVST is a potentially serious condition which manifests with diverse clinical manifestations, from isolated headache to focal neurological signs and even coma. CVST usually takes place either an inherited thrombophilia or any acquired hyperviscosity state and thus prompting anticoagulation was regimen as is the cornerstone of successful treatment. We describe a 47-year-old woman who presented with recurrent bouts of vomiting in the post-operative period and later developed cortical blindness and asymmetric limb weakness. Magnetic resonance imaging (MRI) showed hyperintensity involving bilateral parieto-occipital corticomedullary junction. MR venography showed signal void in the superior sagittal sinus. She was diagnosed as CVST and achieved complete recovery with anticoagulation therapy. Bilateral occipital infarction as a consequence of cerebral venous thrombosis is a rare cause of visual loss. Thrombosis in the superior sagittal sinus was related to her cortical blindness and weakness. This case illustrates that cerebral venous thrombosis should be considered in cases of occipital vascular lesions leading to acute painless loss of vision prompting anticoagulation therapy which can improve the outcome significantly. Dehydration could be considered as a risk factor for development of CVST in appropriate situations.
