| Summary: | Background: Intracranial calcification is a common finding on brain imaging which can be non-specific. The calcification can be physiological or pathological. Likewise, subcortical calcification is a non-specific finding on non-contrast-enhanced computed tomography. This could be secondary to multiple underlying diseases such as Sturge-Weber syndrome, tuberous sclerosis, Fahr disease, post-chemoradiotherapy change, and metabolic disorders secondary to parathyroid or thyroid gland abnormalities. On the other hand, subcortical calcification secondary to arteriovenous malformation and dural venous fistula are uncommon findings. We report two cases with subcortical calcification secondary to these vascular malformations. We aim to highlight the importance of recognising subcortical calcification as one of the possible imaging appearances of dural venous fistula and arteriovenous malformation.
