Abstract
Developmental venous anomaly (DVA)/ Cerebral Venous Angioma is the most common type of cerebral vascular malformations, mostly an incidental benign finding. But there are documented associated complications like parenchymal signal abnormalities, thrombosis, cavernous malformations and parenchymal atrophy.
In this report, we present a unique case of cerebral DVA with cortical changes mimicking the Glioma. Altered haemodynamics in DVA is the underlying pathophysiology for these changes. Correct MRI interpretation, by an expert neuroradiologist, can establish the diagnosis of DVA and its related changes. Therefore, it can reduce the morbidity and mortality by preventing the unnecessary invasive procedures like biopsy for diagnosis.
