Abstract
Introduction
To examine the clinical and radiologic findings of patients with developmental venous anomaly (DVA) associated with intracranial haemorrhage but unrelated to cavernoma.
Methods
Computed tomography (CT) was used to obtain intracranial images from seven patients ranging in age from 6 to 51 years. Magnetic resonance imaging (MRI) was then performed on six patients, and two patients were further examined via CT angiography. Finally, digital subtraction angiography (DSA) was performed to confirm the initial diagnosis.
Results
CT showed intraparenchymal supratentorial haemorrhage in all patients. The combined imaging modalities eventually confirmed a diagnosis of arterialised DVA in four patients and arterialised DVA associated with arteriovenus malformation (AVM) in three. Two patients were managed symptomatically, two underwent radiosurgery, one underwent surgery, one underwent combined embolisation plus radiosurgery and the remaining patient underwent combined embolisation plus surgery. Two patients died, one as a result of re-bleeding, and the other due to radiation necrosis. The mean follow-up period was 33 months (6 months to 6 years) for the remaining five patients with favourable outcome.
Conclusion
DVA associated with intraparenchymal haemorrhage, but not related to cavernoma, was confirmed. Though very rare, DVA may present with non-cavernoma-related haemorrhage in the form of arterialised DVA or DVA with AVM.
