Background: Low-grade arteriovenous malformations (AVMs) associated with multiple flow-related distal anterior cerebral artery (DACA) aneurysms are rare occurrences. Here, we present a case of a frontal AVM with three associated DACA aneurysms arising from a single feeder.
Case description: A 36-year-old male presented to us in the ER with acute-onset dysphasia and altered mental status. Head computed tomography and angiogram showed a spontaneous intracerebral hemorrhage with intraventricular extension and revealed a Spetzler Martin Grade II AVM, being fed by two feeders, with the major feeder from the DACA bearing three flow-related aneurysms. As the patient awaited digital subtraction angiography, his Glasgow Coma Scale dropped and he underwent emergency embolization with Onyx. This was followed by external ventricular drainage. The patient's neurological status did not improve, and he died following a complicated clinical course.
Conclusion: Multiple DACA aneurysms are a case of both clinical and anatomical rarity and to avoid complications in the clinical course, one must be judicious about the time spent between symptom onset and embolization.
