Sonographic findings of cerebral arteriovenous malformations in the fetus are uncommon and usually regard aneurysm of the Galen vein. Outcome of arteriovenous malformations is usually severe. We report a case of a fetus at 21 weeks’ gestation with a rarer arteriovenous malformation, referred to us for echocardiography on account of a suspicious cardiomegaly at obstetrical scan. Upon examination, we found cardiomegaly, together with an associated moderate tricuspid regurgitation, however, there were no clear features of tricuspid dysplasia. Considering an unusually dilated superior vena cava, we found via color Doppler imaging a systodiastolic flow at Color Doppler progressing. Subsequent MRI of the central nervous system determined the localization in the sinus dura mater. Due to an already evident hemodynamic impact, the parents opted for the termination of the pregnancy. Autopsy confirmed a voluminous arteriovenous malformation of the transverse sinus of the dura mater, severe cardiomegaly, mainly of the ventricles, and hypoplasia of the lungs.

Abstract 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. Case presentation We report two cases, whom were a 45-year-old lady and a 20-year-old man, with subcortical calcification on non-contrast-enhanced computed tomography, which were later confirmed to be secondary to chronic venous congestion as the results of dural venous fistula and arteriovenous malformation, respectively. Both patients underwent magnetic resonance imaging of the brain and digital substraction angiography to confirm the diagnosis. Subsequently, both patients were offered embolisation with the 45-year-old lady opting for conservative management and the 20-year-old man waiting for the procedure, at the time of writing. Conclusion Venous congestion secondary to intracranial vascular malformation is an important differential diagnosis for extensive subcortical and basal ganglia calcification. Knowledge on the possibility of vascular malformation to present with subcortical calcification is crucial to avoid misdiagnosis and mismanagement of the patients.
