May 31, 2014 · Cerebrovascular accidents involving azygos ACA present with bilateral ACA territory involvement, which can sometimes mimic an underlying space-occupying lesion. The associations of azygos ACA types with the presence of aneurysm or ACA A1 MR scan of brain showed high signal intensities in both anterior cerebral artery territories, suggesting acute bifrontal infarction (figure 2). The presence of this rare anatomical variant and its potential associated anomalies proved a major consideration in the administration of routine deep vein thrombosis (DVT) prophylaxis. A follow-up inpatient MRI revealed a single anterior cerebral artery, known as an azygous anterior cerebral artery.

Discussion/Differential Diagnosis: The azygous ACA A2 segment is an uncommon anatomic variant seen in less than 1% of the population. The azygos vein (from Ancient Greek ἄζυγος (ázugos), meaning 'unwedded' or 'unpaired') is a vein running up the right side of the thoracic vertebral column draining itself towards the superior vena cava.
