Quadrantanopia as the only symptom of post-COVID stroke in the occipital pole: Case report

RATIONALE: This is a case report describing delayed complications of COVID-19 pneumonia, which evolved into the vascular-ischemic complications leading to quadrantanopia and MRI findings consistent with recent ischemic event in the occipital pole of the brain. PATIENT CONCERNS: We report a case of a 46-year-old woman with quadrantanopia due to stroke confirmed with brain MRI, secondary to COVID-19 infection with chronically elevated D-dimers and treated with anticoagulation/antithrombotic modalities. Quadrantanopia was the only symptom recognized by the patient of a stroke localized in the occipital pole of the brain. DIAGNOSIS: The patient was diagnosed with quadrantanopia due to stroke confirmed with brain MRI, secondary to COVID-19 infection. INTERVENTION: Patient underwent ophthalmological examination and MRI. OUTCOMES: A thrombotic or ischemic risks in the chronic recovery from COVID-19 should be considered in patients with elevated D-dimers. LESSONS: An MRI should be considered as a long term follow up for post-COVID-19 patients reporting ophthalmic or neurologic complains.
